让我们加密Python客户端失败（Certbot自动）

我在下面看到这个错误消息。客户端以前在完全相同的环境中工作。我对Python一无所知

我怎样才能解决这个问题？我目前的证书几小时后到期

发行版或安装版中的python virtualenv版本比Certbot Auto所需的版本旧

通过安装或升级到适用于Python 3的兼容virtualenv版本

pip3 install virtualenv>=15.1.0

看起来您找到了virtualenv 15.0.3，但需要15.1.0。。。回购协议改变了吗？你说的回购协议是什么意思@AIGI不知道原因，您可以尝试使用pip卸载并重新安装virtualenv:pip卸载virtualenv/pip安装virtualenv==15.1.0您正在运行的任何脚本都无法创建虚拟环境。。。上面提到的错误。感觉就像@chrki提到的那样发生了变化。我会从那里开始追逐它。。。以前安装失败了吗？有人更新了吗？等等。@nxrd您可以尝试python-m pip install virtualenv==15.1.0如果安装了pip，但不在您的路径中，则可能会起作用，否则您必须安装它：sudo apt get install python3 pip-或者由于您使用的是python3，它实际上可能被称为pip3
