在 Mac 上安装 pip

Question

我想在 Mac 上安装 pip。 这是我在终端输入的内容：

sudo easy_install pip 

但是，当我想检查 pip 的版本时，会出现以下消息：

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 11, in <module>
    load_entry_point('pip==21.1.3', 'console_scripts', 'pip')()
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources/__init__.py", line 489, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources/__init__.py", line 2843, in load_entry_point
    return ep.load()
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources/__init__.py", line 2434, in load
    return self.resolve()
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources/__init__.py", line 2440, in resolve
    module = __import__(self.module_name, fromlist=['__name__'], level=0)
  File "/Library/Python/2.7/site-packages/pip-21.1.3-py2.7.egg/pip/__init__.py", line 1, in <module>
    from typing import List, Optional
ImportError: No module named typing

我应该如何解决这个问题？

如果您使用的是 Python3，您应该输入“pip3”而不是“pip”。

pip3 --version
