python - pip 安装失败：命令 python setup.py egg_info 失败，错误代码 1

Question

可能重复：
pip install PyQt IOError

我的环境是安装了 python 2.7.2 的 windows 7。

我正在尝试通过 PIP 安装一些软件包，由于找不到 setup.py 而失败，见下文：

C:\MyInstall\Python27\Scripts>pip install PyQt
Downloading/unpacking PyQt
  Downloading PyQt-x11-gpl-4.9.1.tar.gz (9.7Mb): 9.7Mb downloaded
  Running setup.py egg_info for package PyQt
    Traceback (most recent call last):
          File "<string>", line 14, in <module>
    IOError: [Errno 2] No such file or directory: 'C:\\MyInstall\\Python27\\Scripts\\build\\PyQt\\setup.py'
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

  File "<string>", line 14, in <module>

IOError: [Errno 2] No such file or directory: 'C:\\MyInstall\\Python27\\Scripts\\build\\PyQt\\setup.py'

----------------------------------------
Command python setup.py egg_info failed with error code 1 in C:\MyInstall\Python27\Scripts\build\PyQt
Storing complete log in C:\Users\Administrator\AppData\Roaming\pip\pip.log

任何人都可以为这个错误提供一些指导吗？我是 Python 新手
