我有一个Ubuntu 18.04操作系统，安装了两个版本的python； 3.6和2.7。我尝试为python 3.6安装Flask-Enterprise，但得到了：
zeinab@ZiZi:~/PycharmProjects/My_Service$ sudo pip3 install Flask-Enterprise

我发现this answer，并安装了suds-jurko作为suds的替代品，然后尝试再次安装Flask-Enterprise；我遇到了同样的错误。
编辑1：
我尝试将其安装在虚拟环境中，但是得到了相同的结果：
zeinab@Snapp:~$ virtualenv -p python3 testenv
