zsh command cannot found pip

问题

How can I use pip in oh-my-zsh? I was trying to install nltk through pip, but it told me zsh: command not found: pip. When I check plugins under .oh-my-zsh/custom/plugins, there is a folder named pip. I don't know what the problem is.

Edit:

$ echo $PATH
/home/xxx/bin:/usr/local/bin:/home/xxx/bin:/home/xxx/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

$ type pip
pip is an alias for noglob pip

Maybe you have installed both python2 and python3. python3 may have been installed later.

You may try to use pip3 instead of pip.

First, input the command:

pip3 -V

If you see the version, the pip3 can be used.

Then you can input command line to install nltk:

pip3 install nltk

I got a way to help you use pip in zsh. We can use nano to edit files. In nano, ctrl+X to save and exit

In the ~ directory, input the command:

nano .bash_profile

You may see some codes like:

# Setting PATH for Python 3.5
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.5/bin:${PATH}"
export PATH

Copy them and paste them to the end of .zshrc file by using command:

nano .zshrc

Then input the command:

pip -V

If you see the version, pip can be used.

Edit your rc file:

vim ~/.zshrc

Find the config plugins and delete the pip entry.

In a new terminal:

which pip

This will show you the real path of pip

For me it's working to do

python -m pip install [package_name]

instead of

pip install [package_name]

I'm on MacOS and use ZSH. It seems pip 2.7 can't be found, although it is installed. I believe my paths to "pip" are linked wrong (I also have python3 and pip3 installed via brew).

To get around the issue I created an alias. If you don't have an .aliases file, create one in your homedir. Then open the file:

nano ~/.aliases

and add:

## PIP for python2.7 ##
alias pip="python -m pip "

You need to tell ZSH to pick up the alias file (assuming you don't have this setup already). Open your .zshrc:

nano ~/.zshrc

The add the following near the bottom of the file:

[ -f "$HOME/.aliases" ] && source "$HOME/.aliases"

From the terminal, run:

source ~/.zshrc

Or quit your terminal and reopen it.

Now you can run:

pip install <command>
