Question

我正在尝试在Ubuntu上安装虚拟环境，而我的python是3.5。我的命令是：

python3 -m venv my-env/

这提醒我先安装python3-venv，但随后出现以下错误。

apt-get install python3-venv
Reading package lists... Done
Building dependency tree       
Reading state information... Done
python3-venv is already the newest version (3.5.1-3).

这是因为Python3.5不适用于python3 -m venv吗？如果我无法升级python3.5，该怎么办？

在没有root / sudo的情况下，您不能使用apt-get install。是的，您可以jump through hoops，但可以忽略它。
您可以使用不带root用户的anaconda-python。那将是与系统版本不同的独立python。这是另一个问题的主题
您的语言环境混乱
是的，错误消息可能会更好

为什么内置python中不存在venv？应该是to be there 3.3 onwards

Pip是apt的替代选择，默认情况下对用户有效—不需要sudo。您可以手动get pip，但是这很奇怪而且不明智

但是即使 command 不可用，pip module 也应该可以工作，即使用 python3 -m pip仅在pip使用的地方
