#2 编辑-解决方案：

所以我找到了一些可以修复它的方法：https://stackoverflow.com/a/63207387/12291295

如果你之后得到

ModuleNotFoundError：没有名为“zlib”的模块

错误，尝试这个：https://stackoverflow.com/a/62831268/12291295

python3 -m venv env我正在尝试使用或创建一个 venvpython3.8 -m venv venv但出现错误：

Error: Command '['<some_prior_path>/env/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.

与 python3.8 相同<some_prior_path>/env/bin/python**3.8**

但如果我尝试，python3.6 -m venv env它就会按计划执行，然后我就可以激活 venv。

Ubuntu 版本

Release:    18.04

Python版本：

python3 -V 

Python 3.8.0

我尝试过的事情：

取自 ：https://stackoverflow.com/a/62815398/12291295

sudo apt install python3.8 python3.8-venv

&

apt install python3.8 python3.8-venv python3-venv

返回所有内容已安装并更新。

pip install --user virtualenv

返回：

我认为问题就在这里，我不知道如何使它适用于每个 python3 版本，我的意思是为什么它不位于/usr/bin/python3？

编辑

pip 似乎默认安装的是 python3.6 版本，当我尝试

python3.8 -m pip install pip

我得到：

/usr/local/bin/python3.8: No module named pip
