docker - 我的 docker-compose 无法工作并显示“pkg_resources.VersionConflict ...”

问题描述

我的 docker-compose 是由 pip 安装的pip install docker-compose，我的操作系统是 Ubuntu 18.04.3 LTS。

我的 python 版本是 3.6.9，pip 版本是最持久的，docker 版本是 19.03.5 。

然后当我尝试时docker-compose version，我只是得到......

Traceback (most recent call last):
  File "/home/blackcat/.local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 584, in _build_master
    ws.require(__requires__)
  File "/home/blackcat/.local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 901, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/home/blackcat/.local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 792, in resolve
    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.VersionConflict: (docker-compose 1.25.3 (/home/blackcat/.local/lib/python3.6/site-packages), Requirement.parse('docker-compose==1.17.1'))

During handling of the above exception, another exception occurred:

  File "/usr/bin/docker-compose", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/home/blackcat/.local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 3252, in <module>

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'docker-compose==1.17.1' distribution was not found and is required by the application

我用谷歌搜索了很多解决方案，但没有这样的。

解决方案

我使用 apt-get（版本 1.17.1）安装了 docker-compose，并出现“pkg_resources.DistributionNotFound”错误。

我删除了该版本并安装了另一个版本：

sudo curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

它现在确实有效。希望有帮助！
