FileExistsError：[Errno 17] 文件存在：'/root/analytics/venv-nerapi/lib/python3.6/lib-dynload' 同时创建虚拟环境

Question

$virtualenv -p python3.6m  ../venv-nerapi

上面的命令给出以下错误。

Running virtualenv with interpreter /usr/local/bin/python3.6m
Using base prefix '/usr/local'
Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/virtualenv.py", line 352, in copyfile
    os.symlink(srcpath, dest)
FileExistsError: [Errno 17] File exists: '/usr/local/lib/python3.6/lib-dynload' -> '/root/analytics/venv-nerapi/lib/python3.6/lib-dynload'

During handling of the above exception, another exception occurred:

  File "/usr/local/lib/python3.6/site-packages/virtualenv.py", line 2343, in <module>
    main()

    mkdir(name, mode)
FileExistsError: [Errno 17] File exists: '/root/analytics/venv-nerapi/lib/python3.6/lib-dynload'

我关注了Github 问题线程，但没有找到任何运气。 任何人都可以告诉我出了什么问题吗？ 谢谢

原来存在 venv-nerapi 。删除现有的虚拟环境并重新创建它工作正常。
