Question

所以我设置了一个virtualenv，其中包含system-site-packages，名为vrmlmol。在vrmlmol env中，我使用yolk安装了pip 这是输出 -

(vrmlmol)debanjan@thinkpad:~/vrmlmol$ yolk -V PyOpenGL
PyOpenGL 3.1.0b1
PyOpenGL 3.0.2
PyOpenGL 3.0.1
(vrmlmol)debanjan@thinkpad:~/vrmlmol$ yolk -V PyVRML97
PyVRML97 2.3.0a4

如您所见，PyPI中不存在2.x版本的PyOpenGL。当我尝试安装PyOpenGL和PyVRML时，我得到以下依赖失败：

(vrmlmol)debanjan@thinkpad:~/vrmlmol$ pip install -I PyOpenGL PyVRML97

由于这些软件包不存在，我没有看到使用pip安装更新的PyVRML或更旧的PyOpenGL的任何选项。有帮助吗？我试图让一些同事轻松开始他们自己的设置..所以pip对他们来说会很好。

这是PIP最近更改的副作用，默认情况下不允许安装alpha / beta版本。 PyVRML97的最后一个“最终”版本是如此之久以至于它依赖于PyOpenGL 2.x（它已经过时，而且不再可以通过自动化工具从SourceForge中检索）。

不幸的是，我已经失去了最终版本的PyVRML97和OpenGLContext，因为我经常将它们视为PyOpenGL的个人测试环境。在我解决之前，你需要明确指定alpha版本。

要解决特定问题，您需要明确指定PyVRML97版本：

$ pip install "PyVRML97==2.3.0a4"

要安装一个完整的，有效的PyVRML97 / OpenGLContext环境，其中包含Python 2.7（Linux上）所有软件包的最新发布版本，您的命令行将如下所示：

$ virtualenv oglc-env
$ source oglc-env/bin/activate
(oglc-env)$ pip install PyOpenGL PyOpenGL_accelerate "PyVRML97==2.3.0a4" simpleparse numpy "OpenGLContext==2.2.0a3" pydispatcher pillow

您可能会发现枕头需要在系统级别安装额外的依赖项才能安装它（我的机器上已有这些依赖项）。我刚刚在Kubuntu 13.10机器上测试了安装过程，并使用生成的virtualenv运行OpenGLContext演示脚本。

PyVRML97需要较旧版本的PyOpenGL
