Pip安裝錯誤-命令python setup.py egg_info失敗，錯誤代碼為1

Question

我剛剛在Windows 7（32位）機器上安裝了Python 2.7.5 。

嘗試通過Windows控制台安裝Scrapy模塊時，出現以下錯誤：

Command python setup.py egg_info failed with error code 1 in c:\users\compaq\app
data\local\temp\pip_build_COMPAQ\pyOpenSSL
Storing debug log for failure in C:\Users\COMPAQ\pip\pip.log

我已經閱讀了其他主題，建議重新安裝或更新安裝工具。 我已經嘗試過此操作（存在最新的安裝工具），但仍然存在刮擦安裝錯誤。

以下是完整的安裝腳本和失敗信息：

pip嘗試從源代碼構建軟件包。 因此，您將需要庫和VS2008編譯器的開發標頭，而這些標頭的設置都非常麻煩。

從以下位置下載失敗軟件包的預構建二進制文件更加容易： http : //www.lfd.uci.edu/~gohlke/pythonlibs/

然后重試安裝scrapy 。
