Question

pip告诉我，我应该更新。我启动命令后

pip install --upgrade pip

当我使用

pip3 --version

我收到以下错误：

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 635, in _build_master
    ws.require(__requires__)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 943, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 834, in resolve
    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.VersionConflict: (pip 8.1.1 (/usr/lib/python3/dist-packages), Requirement.parse('pip==10.0.1'))

During handling of the above exception, another exception occurred:

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'pip==10.0.1' distribution was not found and is required by the application

我尝试再次安装pip：

sudo apt install python3-pip

但它告诉我

python3-pip is already the newest version (8.1.1-2ubuntu0.4).

我该如何解决此问题？谢谢。

Answer 1

尝试重新安装它。

apt install --reinstall python3-pip

Answer 2

由于仍然没有真正的答案... 我在Linux（CentOS 7）上也遇到了这个问题，并设法解决了这个问题。转到主文件夹。

$ cd ~

如果您需要最新版本：

$ pip3 install --user --upgrade pip

如果您需要特定版本（例如问题中的内容）

$ pip3 install --user pip==10.0.1

Ubuntu：pip版本冲突
