To augment PYTHONPATH, run regedit and navigate to KEY_LOCAL_MACHINE \SOFTWARE\Python\PythonCore and then select the folder for the python version you wish to use. Inside this is a folder labelled PythonPath, with one entry that specifies the paths where the default install stores modules. Right-click on PythonPath and choose to create a new key. You may want to name the key after the project whose module locations it will specify; this way, you can easily compartmentalize and track your path modifications.

谢谢

蟒蛇。X路径可以从上面的几个指令中设置。 Python 3默认安装在 Python C:\Users\当地\ AppData \ \程序\ \ Python35-32 \ 所以这个路径必须添加到windows环境中的path变量中。

在windows上的Python 3.4中，当我将它添加到PATH环境变量而不是PYTHONPATH时，它工作了。就像如果你在D:\Programming\Python34中安装了Python 3.4，那么在PATH环境变量的末尾添加这个

;D:\Programming\Python34

关闭并重新打开命令提示符并执行“python”。它将打开python shell。这也修正了我Sublime 3的“python不被识别为内部或外部命令”的问题。

这些解决方案可以工作，但它们只适用于您的机器上的代码。我会在代码中添加几行如下所示的代码:

import sys
if "C:\\My_Python_Lib" not in sys.path:
    sys.path.append("C:\\My_Python_Lib")

这样你的问题就解决了

只需将您的安装路径(例如C:\Python27\)附加到系统变量中的path变量。然后关闭并打开你的命令行，输入'python'。
