【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 usepython3
instead ofpython
.
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:
- Check the installation location:
Make sure Python is installed in a directory that is in your PATH. - Add the directory to your PATH:
If necessary, add the directory to your.zshrc
or.bash_profile
file. - Restart your terminal:
Restart your terminal for the changes to take effect. - Try using a different shell:
If you're using a different shell, try using the appropriate command to start Python. - Reinstall Python:
If all else fails, try reinstalling Python.
