docker - 我的docker-compose无法正常工作，并向我显示 “pkg_resources.VersionConflict…”

Question

我的docker-compose由pip安装为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，而docker版本是19.03.5。

然后当我尝试docker-compose version时，我得到...

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:

    from pkg_resources import load_entry_point

    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Google搜索了许多解决方案，但是却并非如此。

Answer 1

我使用apt-get(版本1.17.1)安装了docker-compose，并且出现“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

它确实可以正常工作。
希望是有帮助的!
