python无法识别

Question

我正在尝试安装pylint，因为我正在使用VS代码，但我不断收到此错误代码：

PS C:\Users\Alex> python -m pip install pylint
python : The term 'python' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the
spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ python -m pip install pylint
+ ~~~~~~
+ CategoryInfo          : ObjectNotFound: (python:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException

我正在运行Windows 10 64位。

编辑：

我尝试使用'py'代替'python'而且它有效。

PS C：\ Users \ Alex＆gt; py -m pip install pylint
