问题:
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.

Check your .bash_profile 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

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

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.
回答4:
source ~/.nvm/nvm.sh Add this line to ~/.bashrc, ~/.profile, or ~/.zshrc
回答5:
This worked for me:
Before installing nvm, run this in terminal: touch ~/.bash_profile
After, run this in terminal:
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.1/install.sh | bash
Important... - Don't forget to Restart your terminal OR use command source ~/.nvm/nvm.sh (this will refresh the available commands in your system path).
In terminal, use command nvm --version and you should see the version

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.

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
回答8:
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.

Quick answer
Figure out the following:
- Which shell is your terminal using, type in:
echo $0 to find out (normally works) - 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!)
- Add
source ~/.nvm/nvm.sh to that file (assuming that file exists at that location, it is the default install location) - Logout/login
- Profit?
Example
As you can see below 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.

I had fixed this problem.
- touch ~/.bash_profile
- open ~/.bash_profile
- paste
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

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.

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" ] && . "$NVM_DIR/nvm.sh" # This loads nvm
Edit: For those on Mac be aware that macOS doesn't read .bashrc on Terminal start, so using .bash_profile is preferable. See Here.
回答13:
For my case, it because I use fish. if I not start fish, just type nvm will no error now.
回答14:
For me this worked. First check that the file .bashrc has following line
[ -s "$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.

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.

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