gensim安装http://blog.csdn.net/helihongzhizhuo/article/details/47038575

1、windows下的python和pip安装

2、pip install gensim 安装gensim，理论上这样就能安装成功了，结果抛出错误如下：



 numpy.distutils.system_info.NotFoundError: no lapack/blas resources found

  

  ----------------------------------------

  Failed building wheel for scipy



 numpy.distutils.system_info.NotFoundError: no lapack/blas resources found

    

    ----------------------------------------

Command "/usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip-build-ZcDX4a/scipy/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-trjXT2-record/install-record.txt
--single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-ZcDX4a/scipy

接下来开始了解决错误的漫漫长路

3、看错误scipy出错，以及各种查后说依赖 numpy，于是下载了numpy-1.9.2-win32-superpack-python2.7.exe 和 scipy-0.16.0b2-win32-superpack-python2.7.exe安装，结果一安装，扔出错，

python
version 2.7 required,which was not found in the registry

4、解决注册表找不到python2.7的问题

 方法：新建一个register.py 文件，把一下代码贴进去，保存

# script to register Python 2.0 or later for use with win32all
# and other extensions that require Python registry settings

import sys

from _winreg import *

# tweak as necessary
version = sys.version[:3]
installpath = sys.prefix

regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (
installpath, installpath, installpath
)

def RegisterPy():
try:
reg = OpenKey(HKEY_CURRENT_USER, regpath)
except EnvironmentError as e:
try:
reg = CreateKey(HKEY_CURRENT_USER, regpath)
SetValue(reg, installkey, REG_SZ, installpath)
SetValue(reg, pythonkey, REG_SZ, pythonpath)
CloseKey(reg)
except:
print "*** Unable to register!"
return
print "--- Python", version, "is now registered!"
return
if (QueryValue(reg, installkey) == installpath and
QueryValue(reg, pythonkey) == pythonpath):
CloseKey(reg)
print "=== Python", version, "is already registered!"
return
CloseKey(reg)
print "*** Unable to register!"
print "*** You probably have another Python installation!"

if __name__ == "__main__":
RegisterPy()

然后，命令窗口运行脚本文件：

加入注册表成功
5、分别安装 numpy-1.9.2-win32-superpack-python2.7.exe 和 scipy-0.16.0b2-win32-superpack-python2.7.exe 程序，均安装成功；
6、再次执行 pip install gensim 也成功，终于安装完成了
