损坏的 pip3 和 easy_install3：DistributionNotFound

Question

我的pip3好像坏了：

$ pip3 --version
Traceback (most recent call last):
  File "/usr/bin/pip3", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python3/dist-packages/pkg_resources.py", line 2708, in <module>
    working_set.require(__requires__)
  File "/usr/lib/python3/dist-packages/pkg_resources.py", line 686, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3/dist-packages/pkg_resources.py", line 584, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: pip==1.5.6

我试图通过用 easy_install3 重新安装 pip3 来修复它，但是 easy_install3 也坏了：

$ sudo easy_install3 --upgrade pip3
Traceback (most recent call last):
  File "/usr/bin/easy_install3", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python3/dist-packages/pkg_resources.py", line 2708, in <module>
    working_set.require(__requires__)
  File "/usr/lib/python3/dist-packages/pkg_resources.py", line 686, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3/dist-packages/pkg_resources.py", line 584, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: distribute==0.6.24dev-r0

从 apt 重新安装 pip3 也没有帮助。

$ sudo apt-get remove python3-pip
$ sudo apt-get install --fix-missing -t testing python3-pip

我是运行 Debian 7（稳定版）。我从测试库安装了 Python 3.4.2。

Answer 1

让一切恢复正常的最简单方法可能是下载 get-pip.py，然后运行

sudo python3 get-pip.py

这会将 pip 升级到最新版本（当前为 6.1.1）并同时更新 setuptools。

Answer 2

我必须下载运行两个脚本，get-pip.py and ez_setup.py

sudo python3 get-pip.py
sudo python3 ez_setup.py

修复了 pip3 和 easy_install3。
