我想在我的电脑上安装PyMOL。我昨天卸载它因为我之前通过Python（x，y）安装了python 2.7.9，而我的PyMOL安装（我几个月前安装所以我担心我忘了我是怎么做的）使用的是python 2.7.8和结果是PyMOL不再正常工作，例如，看看我拍摄的截图，GUI分子查看器不可见，只是控制台。

我试过使用轮子文件（即 http://www.lfd.uci.edu/~gohlke/pythonlibs/#pymol amd64版本）但我遇到了pip问题。请参阅我的64位Python 2.7.9安装附带的pip，pip的exe文件名为pip2.exe。所以我改变了系统环境变量 PYTHONPATH 至 C:\Python27 （python安装的地方）和 PATH 至 C:\Python27\Scripts 这是哪里 pip2.exe 是（以及pip2.7.exe，easy_install.exe和easy_install-2.7.exe，如果相关）。然后我跑了：

pip2 install pymol-1.7.2.1-cp27-none-win_amd64.whl

从命令提示符，但这给出了错误：

Traceback (most recent call last):
  File "C:\Python27\lib\runpy.py", line 162, in _run_module_as_main
    "__main__", fname, loader, pkg_name)
  File "C:\Python27\lib\runpy.py", line 72, in _run_code
    exec code in run_globals
  File "C:\Python27\Scripts\pip2.exe\__main__.py", line 5, in <module>
ImportError: No module named pip

编辑：＃1

我卸载了python并重新安装了它（64位再次）因为我怀疑在我之前的安装中发生了一些错误（这次它附带的pip包含一个名为pip.exe的文件在Scripts文件夹中），然后我运行了pymol安装再次命令（运行后 pip install wheel-0.24.0-py2.py3-none-any.whl，从这个下载的文件下载 https://pypi.python.org/packages/py2.py3/w/wheel/wheel-0.24.0-py2.py3-none-any.whl#md5=4c24453cda2177fd42c5d62d6434679a ）并收到一个不同的错误，pip.log文件可以在这里找到： http://goo.gl/ORVNPB 。

进一步的尝试

然后我下载了 https://codeload.github.com/evonove/pymol/zip/1.7.4 ，提取其内容并运行

python setup.py构建安装

这给出了输出：
