python - python virtualenv 实例已损坏

问题描述

我使用的是 python3.6.5 virtualenv，但是当我尝试运行任何 pip 和 python 方法时，它开始显示以下错误消息。我知道我可以查看站点包以捕获已安装的包并重建 virtualenv，但是想知道是否有更好的方法来挽救这个：

pip freeze > /tmp/requirements.txt
Failed to import the site module
Traceback (most recent call last):
  File "/home/user/.virtualenvs/venv36/lib/python3.6/site.py", line 703, in <module>
    main()
  File "/home/user/.virtualenvs/venv36/lib/python3.6/site.py", line 683, in main
    paths_in_sys = addsitepackages(paths_in_sys)
  File "/home/user/.virtualenvs/venv36/lib/python3.6/site.py", line 282, in addsitepackages
    addsitedir(sitedir, known_paths)
  File "/home/user/.virtualenvs/venv36/lib/python3.6/site.py", line 204, in addsitedir
    addpackage(sitedir, name, known_paths)
  File "/home/user/.virtualenvs/venv36/lib/python3.6/site.py", line 173, in addpackage
    exec(line)
