centos7 

python2.7

安裝完pip後

執行命令建立專案：

scrapy startproject todayMovie

結果報錯了，如下：

[[email protected] scrapycrawler]# scrapy startproject todayMovie
Traceback (most recent call last):

後面搜尋問題，網上提供了各種各樣的解決方案。比如我近照網上說的安裝瞭如下：

 yum install python-devel

<span style="color:#3f3f3f">pip install pyopenssl –upgrade</span>

也沒有用，後面升級更新系統和pip也沒用

後面就安裝了這個版本，

twisted，網上說不能安裝太高的版本，可以先檢視scrapy需要怎麼樣的版本再安裝怎麼樣的版本。如：

[[email protected] scrapycrawler]# pip install scrapy
Requirement already satisfied: scrapy in /usr/lib64/python2.7/site-packages
Requirement already satisfied: pyOpenSSL in /usr/lib64/python2.7/site-packages (from scrapy)

Requirement already satisfied: setuptools in /usr/lib/python2.7/site-packages (from zope.interface>=3.6.0->Twisted>=13.1.0->scrapy)
 

後面執行命令：

sudo pip install twisted==13.1.0

成功了。

如果上面這安裝不成功，可試下如下方式下載編譯：

wget https://twistedmatrix.com/Releases/Twisted/17.1/Twisted-17.1.0.tar.bz2
tar -jxvf Twisted-17.1.0.tar.bz2
cd Twisted-17.1.0
python setup.py install
