用于烧瓶应用程序的 digitalocean ubuntu 16.0 中的 Letsencrypt ssl 安装问题

Question

当我安装letsencrypt的ssl时出现问题；我在 digitalocean 和 ubuntu 16.4 上将 apache 用于烧瓶应用程序。我已经使用 python3 安装了 virtualenv。我也尝试了一些代码

第 1347 和 1357 行： pip_version = StrictVersion(check_output([python, '-m', 'pip', '--version']) 经过 pip_version = StrictVersion(check_output(['pip', '--version']) 和命令 = [python, '-m', 'pip', 'install', '--no-index', '--no-deps', '-U'] 经过 command = ['pip', 'install', '--no-index', '--no-deps', '-U']

但没有任何积极的结果。我遇到的问题如下： '''

我找到了两种修复此错误的方法：

1. 运行这些命令来升级 pip 然后重新安装 virtualenv：

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，但有一个 virtualenv，后面有一个数字，如 virtualenv-2 或 virtualenv-2.7，则创建一个从 virtualenv 到这些现有文件之一的符号链接。
