Node Version Manager install - nvm command not found

Question

I am trying to install NVM as per these instructions

I typed in this command in terminal:

$ curl https://raw.github.com/creationix/nvm/master/install.sh | sh

After running the install, I restart the terminal and attempt to install Node.js with this command:

$ nvm install 0.8

but I get the response:

-bash: nvm: command not found

I'm not sure what I am doing wrong here.

Additional Info--

I've been looking around for solutions from other posts and forums. I found another solution using

$ git clone git://github.com/creationix/nvm.git ~/.nvm

but this times out every time I attempt that. Any help would be appreciated. Thanks.

Answer 1

Check your .bash_profile, .zshrc, or .profile file. You most likely had a problem during the installation.

You should have the following at the end of one of those files.

[[ -s $HOME/.nvm/nvm.sh ]] && . $HOME/.nvm/nvm.sh  # This loads NVM

The . $HOME/.nvm/nvm.sh is the same as source $HOME/.nvm/nvm.sh

See: Sourcing a File

You can also check to see if you have a .nvm folder.

ls -a | grep .nvm

If you're missing that folder then the installation failed to run the git command. This could be due to being behind a proxy. Try running the following instead.

git clone http://github.com/creationix/nvm.git .nvm

Answer 2

I think you missed this step:

source ~/.nvm/nvm.sh

You can run this command on the bash OR you can put it in the file /.bashrc or ~/.profile to automatically load it

Answer 3

This works for me:

1. Before installing nvm, run this in terminal: touch ~/.bash_profile

2. After, run this in terminal:
   curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.1/install.sh | bash

3. Important... - DO NOT forget to Restart your terminal OR use command source ~/.nvm/nvm.sh (this will refresh the available commands in your system path).

4. In terminal, use command nvm --version and you should see the version

Answer 4

source ~/.nvm/nvm.sh Add this line to ~/.bashrc, ~/.profile, or ~/.zshrc

Answer 5

Quick answer

Figure out the following:

1. Which shell is your terminal using, type in: echo $0 to find out (normally works)
2. Which start-up file does that shell load when starting up (NOT login shell starting file, the normal shell starting file, there is a difference!)
3. Add source ~/.nvm/nvm.sh to that file (assuming that file exists at that location, it is the default install location)
4. Start a new terminal session
5. Profit?

Example

As you can see it states zsh and not bash.

To fix this I needed to add source ~/.nvm/nvm.sh to the ~/.zshrc file as when starting a new terminal my Deepin Terminal zsh reads ~/.zshrc and not bashs ~/.bashrc.

Why does this happen

This happens because when installing NVM it adds code to ~/.bashrc, as my terminal Deepin Terminal uses zsh and not bash it never reads ~/.bashrc and therefor never loads NVM.

In other words: this is NVMs fault.

More on zsh can be read on one of the answers here.

Answer 6

In macOS, i had to source it using source ~/.nvm/nvm.sh command to fix this problem.

After that, add these lines

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm

onto ~/.bash_profile so that nvm will be sourced automatically upon login.

Answer 7

First add following lines in ~/.bashrc file

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

then open terminal and source the nvm.sh script

source ~/.nvm/nvm.sh

Answer 8

Not directly connected to the question, but there is a similar problem that may happen, take a look at this question: Can't execute nvm from new bash

---

Here's my answer on that post, just for the reference:

If you are running from a new bash instance, and you HAVE the initialization code at your ~/.bashrc, ~/.bash_profile, etc, then you need to check this initialization file for conditionals.

On Ubuntu 14, there is a:

case $- in
    *i*) ;;
      *) return;;
esac

At line 6, that will halt it's execution if bash is not being ran with the "-i" (interactive) flag. So you would need to run:

bash -i

Also, at the end of the file, there is a

[ -z "$PS1" ] && return

That will halt it's execution if not being ran with $PS1 set (like on a remote ssh session).

If you do not wish to add any env vars or flags, you will need to remove those conditionals from your initialization file.

Hope that's helpful.

Answer 9

All answers to this questions are useful. Especially the answer given by Travis helped me. For Mac OS X users I would like to provide some steps which will help them to work with the fresh installation of Node Version Manager a.k.a. nvm.

Installing & using nvm on Mac OS X

Here are the steps for fresh installation of nvm and using it without any issue:

• Install homebrew from here.

• Using homebrew install nvm

  brew update brew install nvm

• Create .nvm directory at ~/.nvm location.

  mkdir ~/.nvm

• Now if you don't have .bash_profile file setup for OS X terminal then please create a .bash_profile at the root level:

  nano ~/.bash_profile

• Paste below code in the .bash_profile and press CTRL + O and press enter to save .bash_profile file. Press CTRL + X to exit from editor:

  export NVM_DIR=~/.nvm source $(brew --prefix nvm)/nvm.sh

• Now either quite (CMD + Q) the terminal or run below command to load .bash_profile settings:

  source ~/.bash_profile

• Now run nvm ls command to get the list of all installed nodejs versions.

Answer 10

If you are using OS X, you might have to create your .bash_profile file before running the installation command. That did it for me.

Create the profile file

touch ~/.bash_profile

Re-run the install and you'll see a relevant line in the output this time.

=> Appending source string to /Users/{username}/.bash_profile

Reload your profile (or close/re-open the Terminal window).

.  ~/.bash_profile

Answer 11

Add the following lines to the files ~/.bashrc and ~/.bash_profile :

# NVM changes
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"

and restart the terminal or do source ~/.bashrc or source ~/.bash_profile. If you need command completion for nvm then also add the line:

[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"

Along with the above lines to ~/.bashrc and ~/.bash_profile.

Answer 12

The nvm install script by default adds initialization code to your $HOME/.profile, which is only loaded by a login shell (in a desktop environment you may never see a login shell).

The nvm command in your login shell is not propagated to sub-shells (like console windows and IDE terminals after you log in). This snippet in your $HOME/.bashrc will only load nvm if it is an interactive shell and has not been loaded already

# if nvm dir is not set and the standard nvm directory exists
if [ -z "$NVM_DIR" -a -d "$HOME/.nvm" ] ; then
# set nvm dir
  export NVM_DIR="$HOME/.nvm"
fi

# if nvm dir is set and this shell is interactive
if [ -d "$NVM_DIR" -a -n "$PS1" ] ; then
  # if nvm command is not defined
  if ! type -t nvm >/dev/null ; then
    # set it
    source "$NVM_DIR/nvm.sh"
  fi
fi

Putting this in your $HOME/.bashrc file will fix the missing nvm problem in interactive bash shells, even from a gui, and even if nvm is installed in a non-standard location.

Answer 13

I had fixed this problem.

1. touch ~/.bash_profile
2. open ~/.bash_profile
3. pasteexport NVM_DIR="$HOME/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion

Answer 14

For the issue was fixed when I moved

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

to the end of .zshrc

Answer 15

On Debian, as well as adding the below lines to my .bash_profile as one of the above answers said. I also had to open up my terminal preferences (Edit -> Profile Preferences -> Command) and enable 'Run command as a login shell' to get it to work.

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm

Edit: For those on Mac be aware that macOS doesn't read .bashrc on Terminal start, so using .bash_profile is preferable. See Here.

Answer 16

For my case, it because I use fish. if I not start fish, just type nvm will no error now.

Answer 17

For me this worked. First check that the file .bashrc has following line

[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm

Now bashrc is loaded for each terminal session. Thus restart the terminal so that it is loaded again and you should be good to go.

Answer 18

In Windows 8.1 x64 same happened with me, and received the following message.

nvm install 8.3.0 bash: nvm: command not found windows

So, follow or verify below following steps-

first install coreybutler/nvm-windows from github.com. Currently available latest release 1.1.5 nvm-setup.zip, later extracted the setup nvm-setup.exe and install as following locations:

NVM_HOME    : C:\Users\Administrator\nvm
NVM_SYMLINK : C:\Program Files\nodejs

and meanwhile setup will manage the environment variable to Path as above said for you.

Now run Git Bash as Administrator and then.

$ nvm install 8.3.0 all

Downloading node.js version 8.3.0 (64-bit)...
Complete
Creating C:\Users\Administrator\nvm\temp

Downloading npm version 5.3.0... Complete
Installing npm v5.3.0...

Installation complete. If you want to use this version, type

nvm use 8.3.0

$ nvm use 8.3.0
Now using node v8.3.0 (64-bit)

here run your command without using prefix $, it is just shown here to determine it as a command line and now we will verify the nvm version.

$ nvm --version
Running version 1.1.5.

Usage:
-----------------------

if you have problem using nvm to install node, you can see this list of available nodejs releases here https://nodejs.org/download/release/ and choose the correct installer as per your requirement version equal or higher than v6.3.0 directly.

Answer 19

I also faced the same problem recently and sourcing nvm bash script by using source ~/.nvm/nvm.sh resolved this issue.

Answer 20

Use following codes

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash`
source ~/.nvm/nvm.sh`
nvm install 0.8

Answer 21

After trying multiple steps, not sure what was the problem in my case but running this helped:

touch ~/.bash_profile
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.32.1/install.sh | bash

Verified by nvm --version
