在homebrew中更新pip和setuptools不起作用

Question

在brew install python之后，会出现以下内容：

Pip and setuptools have been installed. To update them
  pip2 install --upgrade pip setuptools

正在运行pip2安装

pip2 install --upgrade pip setuptools
Traceback (most recent call last):
  File "/usr/local/bin/pip2", line 11, in <module>
    load_entry_point('pip==9.0.1', 'console_scripts', 'pip2')()
  File "/Users/user1/Library/Python/2.7/lib/python/site-packages/pkg_resources/__init__.py", line 564, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/Users/user1/Library/Python/2.7/lib/python/site-packages/pkg_resources/__init__.py", line 2661, in load_entry_point
    raise ImportError("Entry point %r not found" % ((group, name),))
ImportError: Entry point ('console_scripts', 'pip2') not found

Answer 1

在使用Homebrew从Python 2.7.13升级到2.7.14之后，我遇到了这个问题。我在GitHub：https://github.com/pyenv/pyenv/issues/739上使用了这期杂志中的建议，它对我很有效。我实际运行的命令是：

/usr/local/Cellar/python/2.7.14/bin/python2 -m pip install --upgrade --force-reinstall pip

祝好运。
