Virtual environment already activated: /home/harshagoli/.cache/pypoetry/virtualenvs/my-project-0wt3KWFj-py3.7

我怎样才能克服这个错误？为什么这个命令不起作用

Answer 1

poetry shell是一个真正有缺陷的命令，维护人员经常讨论这个问题。此特定问题的解决方法是手动激活shell。下面的代码可能值得使用别名

source "$( poetry env list  full-path )/bin/activate"

Answer 2

这类似于激活正常的虚拟环境。但我们需要找到诗歌虚拟环境的路径

我们可以通过poetry env info path找到路径

source $(poetry env info  path)/bin/activate

在this poetry demo中解释

Answer 3

我必须做以下几件事

source "$( poetry env list  full-path | grep Activated | cut -d' ' -f1 )/bin/activate"
