IndentationError：创建python3 virtualenv时出现意外缩进

Question

以前我的virtualenv 命令完全适用于python3。但是现在当我尝试创建一个虚拟环境时：

$ virtualenv -p python3 .

它给了我以下错误：

Running virtualenv with interpreter /home/user/anaconda3/bin/python3
Already using interpreter /home/user/anaconda3/bin/python3
Using base prefix '/home/user/anaconda3'
New python executable in /home/user/Documents/cynical/sitemap/bin/python3

我也尝试过更新 pip3、python3 和 virtualenv。

$ apt install python3
$ apt install python3-pip
$ apt install virtualenv

我找到了解决办法！我做到了：

$ pip install --upgrade pip
$ pip install --upgrade virtualenv

希望这也适用于您！
