我把诗歌和pyenv结合起来做一些爱好项目。我用pyenv在一些诗歌爱好项目中创建了一些虚拟的env。出于某种原因，我删除了一些python安装，这些安装破坏了这些项目中的虚拟环境，现在诗歌不再工作了。当我开始写诗的时候，我得到了这样的信息。我使用的是Linux Mint 20.1:
/home/milkman/.poetry/lib/poetry/_vendor/py2.7/subprocess32.py:149: RuntimeWarning: The _posixsubprocess module is not being used. Child process reliability may suffer if your program uses threads.
"program uses threads.", RuntimeWarning)

我不知道从哪里开始解决这个问题。每当我尝试使用诗歌命令时，我都会得到相同的消息。有人能给我指个方向吗?
谢谢!
可能是您删除了一些库文件。你可以尝试删除诗歌和你的应用程序正在使用的所有库。开始新的诗歌装置。您可以使用pip来安装和卸载
否则，从头开始一个新项目。
似乎您不小心删除了库的一些函数。试着把它删除然后重新安装。
