Answer 1

检查您的 python 最近是否更新。 venv 可能指向旧的，重新创建 venv 为我们修复它。

运行 mkvirtualenv venv 或 virtualenv venv（取决于您最初是如何创建它的）也应该在保留已安装的软件包的同时工作。

Answer 2

！介意的真是热修复！

此问题出现在新版本 python - 3.6.3.

降级到 3.6.2 对我有帮助

这是旧版 PPA：https://launchpad.net/~fkrull/+archive/ubuntu/deadsnakes/+index?batch=75&direction=backwards&start=75

降级进一步操作的命令python:

sudo apt install libpython3.6-minimal=3.6.2-1+xenial1 sudo apt install python3.6-minimal=3.6.2-1+xenial1 sudo apt install python3.6-stdlib=3.6.2-1+xenial1 sudo apt install python3.6=3.6.2-1+xenial1

Answer 3

这发生在我升级到 3.6.3 后尝试使用 Python 3.6.3 或更新版本创建新的 virtualenv。这解决了我的问题。

Answer 4

这解决了我的问题：

cd /usr/bin
sudo cp python3.6 python3

之前我有3.6.2，做了之后apt-upgrade系统坏了
