当我安装letsencrypt get问题的ssl 时;我在DigitalOcean和Ubuntu 16.4上使用Apache for Flask应用程序。我已经使用 python3 安装了 virtualenv。我也尝试了一些代码
1347和1357行： pip_version = StrictVersion(check_output([python， '-m'， 'pip'， '--version']( 由 pip_version = StrictVersion(check_output(['pip'， '--version']( 和命令 = [python， '-m'， 'pip'， 'install'， '--no-index'， '--no-deps'， '-U'] 由 命令 = ['pip
'， 'install'， '--no-index'， '--no-deps'， '-U']但不是任何可能的结果。我遇到这样的问题： '''

我找到了两种修复此错误的方法：
- 运行以下命令以升级 pip，然后重新安装 virtualenv：
pip install --upgrade pip
pip uninstall virtualenv
pip install virtualenv
- 检查 virtualenv
- 的位置 - 它可能在/usr/bin/virtualenv 中。如果它不存在，但有一个 virtualenv 后面有一个数字，如 virtualenv-2 或 virtualenv-2.7，那么从 virtualenv 到这些现有文件之一的符号链接。
