破碎PIP3和easy_install3：DistributionNotFound

Question

我pip3似乎被打破：

$ 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 

我試圖通過重新安裝pip3與easy_install3修復它，但easy_install3也斷了：

$ 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 

從重新安裝PIP3也沒有幫助。

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

我正在運行Debian 7（stable）。我從測試庫安裝了Python 3.4.2。

Answer 1

我必須下載並運行兩個腳本，get-pip.py和ez_setup.py

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

那些固定兩個PIP 3和easy_install3。

Answer 2

可能得到一切再次合作的最簡單的方法是下載get-pip.py，然後運行

sudo python3 get-pip.py 

這將升級pip到最新版本（6.1.1目前）和更新setuptools爲好。
