所以我目前正在尝试升级 Windows 子系统上 ubuntu 上的 bash 中的 python 版本。但是据我了解，从命令行更新 python 并不容易。最后，我的 unix 子系统到底“在哪里”？例如，我的文件系统上是否有类似 unix 的部分，我可以将文件拖入其中？谢谢

最佳答案

这是一个较老的问题，但是我今天不得不做同样的事情(在我的 Windows 10 笔记本电脑上使用 python3.6)。

按Windows + R(打开运行命令对话框)
输入:bash + 按 Enter

您将获得一个新的 windows bash 提示窗口。

首先键入 lsb_release -a 以检查您是否在 Windows 机器上运行最新的 bash/ubuntu 环境(可能是 ubuntu 14.04，而 16.04 是当前版本)。

raz@HOSTNAME:~/myPlayground$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.4 LTS
Release:        16.04
Codename:       xenial

如果您通过运行 do-release-upgrade 运行旧版本升级

raz@HOSTNAME:~/myPlayground$ sudo do-release-upgrade
[sudo] password for raz:
Checking for a new Ubuntu release
No new release found.

添加PPA自定义仓库(标准apt仓库目前只有3.5个)

raz@HOSTNAME:~/myPlayground$ sudo add-apt-repository ppa:jonathonf/python-3.6
 A plain backport of *just* Python 3.6. System extensions/Python libraries may or may not work.

Don't remove Python 3.5 from your system - it will break.
