Python3 : Trying to upgrade pip3 in Ubuntu 16. 04 但它不更新

Question

基本上，标题。我想升级 pip，因为我无法在 python 中获取新包，因为它已过时。

当我尝试从 Ubuntu 终端运行 pip3 install --upgrade pip 时，发生了这种情况:

    Collecting pip
  Using cached pip-9.0.3-py2.py3-none-any.whl
Installing collected packages: pip
  Found existing installation: pip 9.0.1
    Uninstalling pip-9.0.1:
      Successfully uninstalled pip-9.0.1
  Rolling back uninstall of pip
Exception:

You are using pip version 9.0.1, however version 9.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

我该如何解决这个问题？我试图清除 pip 并重新安装它，但无济于事。

编辑:另外，也用 pip 尝试了升级命令，但它似乎没有用。

我有两种方法可以解决你的问题

1. 按照上面的回答尝试使用 sudo。

   sudo pip3 install --upgrade pip

2. 尝试重新安装 pip

   apt-get 删除 python3-pip

   pip3 安装-U pip

注意:这可以通过用 pip2 替换 pip3 来为 python2x 完成
