I'm on Mac OSX, and am running on Mountain Lion. A year or so ago, I installed PyGame so I could program in Eclipse. I was pretty satified, although the lack of code completion threw me off a bit. I plowed through it, and have managed to put up with everything so far. Then, today, I decided to try some PyOpenGL. I installed it using pip, and I copied and pasted he following code into my windows (I'm going to continue here as the actual code isnt the problem). Almost everything gives a warning. Almost everything. The sidebar is a solid wall of yellow.

Lines of code like 

glBegin(GL_TRIANGLES)

give me errors like

undefined variable: GL_TRIANGLES
undefined variable: glBegin

Even going into Eclipse>Preferences>Pydev>Editor>Code Analysis and telling Eclipse to ignore undefined variables doesnt help. Other modules like Pygame do this for me too.

This bothers me. A lot. And I really don't want to be forced back into LWJGL and java.

Is there any way I can fix this problem once and for all?

我在 Eclipse 和 PyOpenGL 中使用 PyDev 没有任何问题。我安装了 OpenGL pip install pyopengl，然后进入 Window > Preferences > PyDev > Interpreter - Python。在不更改任何内容的情况下点击应用。出现提示时，选择适当的解释器进行刷新。完成后，关闭首选项，然后关闭文件 > 重新启动。这立即起作用：

from OpenGL.GL import GL_TRIANGLES
