用于烧瓶应用程序的数字海洋ubuntu 16.0中的ssl安装问题

Question

当我安装ssl的letsencrypt获取问题时，我在数字海洋和ubuntu16.4上使用apache作为烧瓶应用程序。我使用python3安装了virtualenv。我也尝试过一些代码

第1347和1357行: pip_version = StrictVersion(check_output(python，'-m'，'pip'，‘-version’)，pip_version = StrictVersion(check_output('pip'，‘-version’)，命令= python，'-m'，'pip'，'install'，‘-no-index’，‘-no-index’，‘-no-deps’，'-U‘by命令= 'pip'，'install'，’-no-index‘，“-没有-”，-

但没有任何可能的结果。我的问题是：‘

我找到了两种修复此错误的方法：

1. 运行以下命令来升级pip，然后重新安装

pip install --upgrade pip
pip uninstall virtualenv
pip install virtualenv

1. 检查virtualenv的位置-它可能在/usr/bin/virtualenv中。如果它不存在，但那里有一个虚拟文件，其后面有一个数字，如虚拟one 2或virtualenv-2.7，则创建一个符号链接，将其从virtualenv到其中一个现有文件。
