This should normally fix it but python is still not recognized. I need help. 回答1: Make sure the path is in your System PATH variable and not in a User PATH variable.

问题 I'm unit testing some Java code that must parse an input String as a path-name. I'm using Java 7, so the parsed value is a Path object. The Paths.get method will throw an InvalidPathException if the path string cannot be converted to a Path So, to check my parsing code is robust I need a test value that will cause Paths.get to throw that exception. That is, a String value that is not a valid path. What constitutes a valid path is system (even file-system) dependent, so I am specifically
