python3安装后没有pip_python-3.x – pip3安装无法正常工作 – 没有名为’pip._vendor.pkg_resources’的模块...
当尝试使用pip3 install packageName(或sudo pip3 install packageName)安装
Python 3的包(在Ubuntu中)时,我收到以下错误消息：
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 33, in vendored
__import__(vendored_name, globals(), locals(), level=0)
ImportError: No module named 'pip._vendor.pkg_resources'
我已经阅读了几天,并尝试了以下没有任何成功：
>使用以下代码卸载并重新安装pip3：sudo apt-get remove python3-pip,然后是sudo apt-get install python3-pip.有几个帖子表示有时pip3无法正确安装Ubuntu.但是,它没有用.
>其他帖子暗示这是一个ssl包问题,如果ssl包没有加载到Python3上,那就是问题所在.但是,以下命令不会引发任何错误：python3 -c“import ssl”.
>其他一些帖子建议问题在于请求包.然后我尝试了sudo apt-get删除python3-requests后跟sudo apt-get install python3-requests也无济于事.
您可能需要的其他信息：
> pip3 –version给出了我上面报告的相同错误.
> dpkg -L python3-pip给出了以下信息：

我怎样才能让pip3工作？
注意：Python2的pip工作得很好.
