python ----Linux上安裝scrapy

在安裝scrapy之前首先得確保你已經安裝了python 以及pip

1，安裝scrapy

pip install scrapy

如果報錯：Could not find a version that satisfies the requirement Twisted>=13.1.0 (from Scrapy) (from versions: )
No matching distribution found for Twisted>=13.1.0 (from Scrapy)

原因是沒有安裝Twisted

2，安裝Twisted。

wget https://pypi.python.org/packages/source/T/Twisted/Twisted-15.2.1.tar.bz2 --no-check-certificate
tar -xjvf Twisted-15.2.1.tar.bz2
cd Twisted-15.2.1
python setup.py install

　　成功。
