从 matplotlib 导入 *

我收到未找到的响应。我将带有模块的文件夹添加到 PythonPath，但不断收到相同的消息。我做错了什么？

来自 pydev tutorial (根据我的经验，与您的问题相关的两种最常见的情况):

1)

The most common error is having a problem in the environment variables used from the shell that spawned Eclipse, in a way that for some reason when getting the variables of one interpreter, it gathers the info from another interpreter (thus mixing the interpreter and the actual libraries).

2)

If you add something to your python installation, you need to either add it manually as a 'new folder' in the System PYTHONPATH (if it's still not under a folder in the PYTHONPATH) or (recommended) remove your interpreter and add it again, then, press apply.
