Python PyVRML97需要PyOpenGL的旧版本

所以我设置了一个virtualenv，打开系统站点包，名为

vrmlmol

。在

vrmlmol

env内部，我安装了

yelk

和

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

正如您所见，PyPI中不存在PyOpenGL的2.x版本。当我尝试安装PyOpenGL和PyVRML时，出现以下依赖项故障：

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

由于这些软件包不存在，我看不到使用pip安装较新的PyVRML或较旧的PyOpenGL的任何选项。有人帮忙吗？我试图让一些同事更容易开始自己的设置。。所以皮普会很高兴有他们

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”版本非常陈旧，它依赖于PyOpenGL 2.x（该版本早已过时，不再可以通过自动化工具从SourceForge中检索）

不幸的是，我在发布PyVRML97和OpenGLContext的最终版本时失职了，因为我经常把它们当作我个人的PyOpenGL测试环境。在我着手修复之前，您需要明确指定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"

要使用Python 2.7（Linux上）上所有软件包的最新发布版本安装完整、可工作的PyVRML97/OpenGLContext环境，您的命令行如下所示：

$ 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，pillow需要在系统级别安装额外的依赖项才能安装（我的机器上已经安装了这些依赖项）。我刚刚在Kubuntu 13.10机器上测试了安装过程，并使用生成的virtualenv运行了OpenGLContext演示脚本
