Zsh 命令找不到 pip

如何在 oh-my-zsh 中使用 pip？我试图通过 pip 安装 nltk，但它告诉我 zsh: command not found: pip。当我在 .oh-my-zsh/custom/plugins下检查插件时，有一个名为 pip的文件夹。我不知道有什么问题。

编辑 :

$ 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 ABC0 to edit files. In nano, ABC1+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>

If you're running into this issue, it probably is due to versioning complications. Python 2 versus Python 3 on your OS may be resolving unexpectedly. Below is a quick workaround to get you to functioning behavior.

Try using the below for Python 2: python -m pip install <command>

Try using the below for Python 3: pip3 install <command>

In case you do

which pip

and it doesn't show the path, just do

which pip3

This will print the path which is /usr/local/bin/pip3 Then do open ~/.zshrc or nano ~/.bash_profile.

Make alias for pip like:

alias pip=/usr/local/bin/pip3

N.B: You copy that line above and paste in your .zshrc file.

After do source ~/.zshrc and close .zshrc

My pip script is missing for some reason, so I have to install it.

$ python -m ensurepip --upgrade

More methods can be found here:pip installation

小开

You should consider upgrading.

Enter this in your terminal

/Library/Frameworks/Python.framework/Versions/3.10/bin/python3.10 -m pip install --upgrade pip

and then...

Type: pip -V

小开

If you installed python3.x, you should run with pip3(not pip)

小开

In my case my OS was Ubuntu 20.04 and the pip doesn't come with python.

So, i've installed pip through the command

sudo apt install python3-pip

and I'm done.

To ensure run pip -V or pip3 -V

小开

So you are using oh-my-zsh framework for zsh or Z shell. First, try the command:

pip3 -V

If you get something like this below, that means you have the pip3 package already and must be having python3 as well.

pip 22.0.4 from /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/pip (python 3.10)

Then edit your .zprofile instead of .bashprofile as you are using zsh. This is the command.

nano ~/.zprofile

Then it should have the two alias like this.

# Setting PATH for Python 3.10
# The original version is saved in .zprofile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.10/bin:${PATH}"
export PATH


alias python=python3
alias pip=pip3

Make sure you save it. Exit and Re-open you terminal. Type the command:

pip -V

It should have the same result as the pip3 -V like this:

❯ pip -V
pip 22.0.4 from /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/pip (python 3.10)

Then you can use pip or pip3 interchangeably for installing your nltk package like this.

pip install nltk
