python-virtualenv is already the newest version.
virtualenv is already the newest version.

Creating virtual environment...
Traceback (most recent call last):
  File "/usr/local/bin/virtualenv", line 7, in <module>
    from virtualenv import main
ImportError: No module named virtualenv

到这里就停止了，造成 Let ’ s Encrypt 证书续期无法完成，求解？

Answer 1

pip install virtualenv

Answer 2

如果你是用centos，请尝试：

yum install python-virtualenv

Answer 3

我也碰到这个问题了！目前一直没有解决呢！不过，我建议你使用acme.sh快速部署生成Let’s Encrypt免费证书，这个不会依赖系统库的！

Answer 4

我个人用 webmin 里面的内置模块申请证书
