安装Scrapy和pyOpenSSL时出现Cmd退出状态1错误

Question

我正在尝试安装scrapy，目前已经安装了依赖项Twisted Matrix、OpenSSL，还有可能其他一两个。我使用的是easy install，当我输入这个命令时

easy_install Scrapy 

我收到了这个错误。

另外，我也尝试重新安装这些依赖项，当我尝试用这个命令安装pyOpenSSL时

easy_install pyOpenSSL

也出现了同样的错误。

有没有人能帮我解决这个问题？

以下是我在多台Windows电脑上安装Scrapy的步骤，希望对你有帮助。

安装Python 2.7.x

• 把C:\python27和C:\python27\scripts添加到你的系统路径中

下载并安装pip：

• 下载get-pip.py文件（可以在这个链接找到：http://pip.readthedocs.org/en/latest/installing.html）

• 运行命令：python get-pip.py

安装Scrapy

• 运行命令：pip install scrapy

下载并安装2008版Visual C++ Redistributable（编译器）

• http://www.microsoft.com/en-us/download/details.aspx?id=29

下载pywin32可执行文件并安装

• http://sourceforge.net/projects/pywin32/files/pywin32/
