python - 在 macOS Sierra 上安装 pip

Question

我一直在尝试通过 brew 在 macOS sierra 上安装 pip，但每次它完成时都没有在 /usr/local/Cellar/python/2.7.13/bin 中安装二进制文件。

我试过了:

MacBook-Pro ➜ brew reinstall python

然后:

MacBook-Pro ➜  ~ which pip
pip not found

我找到了 python 的路径，即 /usr/local/Cellar/python/2.7.13/bin 但那里没有 pip 的二进制文件。

我也尝试了 easy_install 方法:

MacBook-Pro ➜ sudo easy_install pip
Traceback (most recent call last):
  File "/usr/bin/easy_install-2.7", line 11, in <module>
    load_entry_point('setuptools==18.5', 'console_scripts', 'easy_install')()
  File "/Library/Python/2.7/site-packages/pkg_resources.py", line 352, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/Library/Python/2.7/site-packages/pkg_resources.py", line 2307, in load_entry_point
    return ep.load()
  File "/Library/Python/2.7/site-packages/pkg_resources.py", line 2021, in load
    entry = __import__(self.module_name, globals(),globals(), ['__name__'])
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/setuptools/__init__.py", line 12, in <module>
    from setuptools.extension import Extension
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/setuptools/extension.py", line 8, in <module>
    from .dist import _get_unpatched
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/setuptools/dist.py", line 21, in <module>
    packaging = pkg_resources.packaging
AttributeError: 'module' object has no attribute 'packaging'

更新:

当我运行 brew postinstall python 我收到以下错误:

MacBook-Pro ➜  ~ brew postinstall python

您只需要安装 macOS Sierra 中不会自动安装的 pip。

运行 sudo easy_install pip
