【已解决】安装Scrapy过程中出错：error: Could not find ‘openssl.exe’

【问题】

安装scrapy过程中出错：

E:\Dev_Tools\python\Scrapy>pip install Scrapy

【解决过程】

1.参考之前在

【已解决】安装Scrapy过程中出错：ERROR: ‘xslt-config’ 不是内部或外部命令，也不是可运行的程序 或批处理文件。

所遇到的，试了试去打开

http://pypi.python.org/simple/openssl

但是url无效。

2. 又参考:

Trying to install Scrapy – error: Could not find ‘openssl.exe’

去http://pypi.python.org/pypi/pyOpenSSL/0.13下载

pyOpenSSL-0.13.winxp32-py2.7.msi

安装完毕，再去重新安装scrapy，结果还是同样的错误：

Downloading/unpacking pyOpenSSL (from Scrapy)
  Running setup.py egg_info for package pyOpenSSL

    error: Could not find 'openssl.exe'
    Complete output from command python setup.py egg_info:

3. 很奇怪。感觉也许是，刚才安装openssl的时候，默认选择的是从registry中找python路径的，估计没找到正确的。

所以现在去安装路径：

E:\dev_install_root\Python27\Lib\site-packages

也没有找到openssl。

4. 重新运行pyOpenSSL-0.13.winxp32-py2.7.msi

删除掉刚安装的，再重新安装，然后选择路径是选择成自己设置的路径：

然后安装完毕后。

再去重新试试scrapy是否可以识别了。

结果，貌似的确解决了这个openssl的问题了。

【总结】

pyOpenssl安装文件，貌似无法正确检测到pyhon 2.7的安装路径，需要在安装时，手动选择才可以。
