如何让“python”在 WSL bash 中运行 Python 3？

当我打字时python进入 Windows 10 Home 中的 bash shell（适用于 Linux 的 Windows 子系统）时，我收到以下错误消息：

The program 'python' can be found in the following packages:
 * python-minimal
 * python3
Try: sudo apt install <selected package>

我尝试过安装python3但我被告知它已经安装并且是最新的。

我尝试过卸载python-minimal但我被告知它没有安装（！）

为什么我会看到两个“竞争”的 Python 包？如何修复冲突并配置 WSL bash 以运行 Python 3python?

如果您在 WSL 下运行 Ubuntu 20，则有一个名为python-is-python3:

cameron@Nook:/mnt/c/Users/camer$ sudo apt install python-is-python3

或者，您可以使用update-alternatives:

sudo update-alternatives --install /usr/bin/python python $(readlink -f $(which python3)) 3
