 【macOS】【zsh Error】zsh: command not found: python

本地已经安装了Python，且能在Pycharm中编译Python程序并运行。

但是，在macOS终端，运行Python，报错。

首先要确认你在macOS系统下，是否安装了Python。

如果安装了，还要确认Python名称。

例如，我在终端输入python，报错：zsh: command not found: python。

而实际上，我的Python，安装在路径：/usr/local/bin

且文件名为：Python3.

所以，需要在终端输入：python3，才能正确运行。

下面是配置环境变量的步骤：

There are a few possible reasons why you might be getting this error:

1. Python is not in your PATH:

• Check the installation location: 
  Make sure you installed Python to a directory that is in your system's PATH.
  Common locations include /usr/local/bin or /opt/anaconda3/bin.

• Add the directory to your PATH: 
  If the directory is not in your PATH,
   you can add it by editing your .zshrc or .bash_profile file. 
  For example,
   if Python is installed in /usr/local/bin,
   you would add the following line to your .zshrc file:

  Bash

  export PATH="/usr/local/bin:$PATH"
  

  【Note】:
  Goodmao has successfully completed the Python installation and configured the PATH environment variable.

  vi ~/.bash_profile
  /usr/local/bin 

• Restart your terminal: 
  After making changes to your .zshrc or .bash_profile file,
   you need to restart your terminal for the changes to take effect.

2. You're using the wrong shell:

• Make sure you're using the correct shell. 
  If you're using a different shell, such as bash,
   you might need to use a different command to start Python. 
  For example, in bash, you would use python3 instead of python.

3. Python is not installed correctly:

• If you're still having trouble, it's possible that Python is not installed correctly. 
  Try reinstalling Python or checking the installation logs for any errors.

Here's a summary of the steps you can take to resolve the issue:

1. Check the installation location: 
   Make sure Python is installed in a directory that is in your PATH.
2. Add the directory to your PATH: 
   If necessary, add the directory to your .zshrc or .bash_profile file.
3. Restart your terminal: 
   Restart your terminal for the changes to take effect.
4. Try using a different shell: 
   If you're using a different shell, try using the appropriate command to start Python.
5. Reinstall Python: 
   If all else fails, try reinstalling Python.
