使用 Windows 10。
首先,我卸载所有现有的 Python 3 或 Python 2.0 版本
https://www.python.org/ftp/python/3.6.0/python-3.6.0-amd64.exe
然后我运行上面的程序,Windows 似乎安装成功了(我选择“将 Python 3.6 添加到路径”)。我点击“立即安装”。
我运行 Windows Powershell。
我输入 python3 但什么也没发生。
PS C:\Users\d> python

有人能建议我该怎么做才能安装 Python 3.6 吗?
答案1
对于那些关注的人来说,为了让 Python 在 Windows 上运行,在安装过程中选择默认选项是不够的。
您必须选择自定义 - 我不知道我在自定义中选择了哪个选项,但我安装到 c:\python36 并为所有用户安装并告诉它设置路径,之后它就起作用了。
