pip3和python3 -m pip之间的区别 [英] Difference between pip3 and python3 -m pip

问题描述

我正在尝试使用pip和python3安装一些软件包.我使用的是MacOS，因此默认情况下，当我运行pip时，它将使用我的Python 2版本.

I am trying to install some packages using pip and python3. I am using MacOS, so by default when I run pip, it uses my version of Python 2.

我已经能够通过使用以下命令在python 3中安装软件包:

I have been able to install a package in python 3 by using:

$ pip3 install package_name

但是，我能够做到(至少看起来如此):

However, I am able to do the same by (at least it seems):

$ python3 -m pip install package_name

我想知道pip3和python3 -m pip是否具有相同的效果.

I wonder whether or not pip3 and python3 -m pip have the same effect.

推荐答案

它们是相同的.如果您查看bin文件夹中的pip3文件，它将从pip模块调用main函数.

They are the same. If you look at the pip3 file in the bin folder it calls the main function from the pip module.

pip3 install package_name在bin文件夹中运行pip3文件:

pip3 install package_name runs pip3 file in the bin folder:

# bin/pip3 
# or bin/pip if using pip install package_name

import re
import sys

from pip import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

python3 -m pip install package_name运行 pip

python3 -m pip install package_name runs the __init__.py file of the pip module.

# pip/__init__.py
if __name__ == '__main__':
    sys.exit(main())

它们都运行相同的main()函数
