Question

所以我现在正试图在Windows子系统上的ubuntu上的bash中升级python版本。但是根据我的理解，从命令行更新python并不容易。最后，＆＃34;其中＆＃34;究竟是我的unix子系统？例如，我的文件系统上有类似unix部分的东西，我可以将文件拖入其中吗？感谢

这是一个比较老的问题，但是我今天必须做同样的事情（在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计算机上运行了最新的bash / ubuntu环境（可能是ubuntu 14.04，而当前版本是16.04）。

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自定义存储库（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.

Answer 2

您可以搜索“开始”菜单＆＃39;为了＆＃39; Bash＆＃39;并获得将在Ubuntu Linux（而不是Unix）中打开命令提示符的应用程序。

AFAIK你不能从Explorer.exe拖放到这个，但你可能能够运行一个Linux文件应用程序，可以安装X11。

最后，从Uashntu命令行应用程序上的Bash，您可以运行＆＃39; sudo apt-get install python3＆＃39;获取最新的Ubuntu。

在Windows上的Ubuntu上升级Bash上的python版本？
