在“pip install cryptography"期间缺少 pyconfig.h [英] pyconfig.h missing during "pip install cryptography"

问题描述

我想按照这个链接设置scrapy集群 scrapy-cluster，在我运行这个命令之前一切正常:

I wanna set up scrapy cluster follow this link scrapy-cluster,Everything is ok before I run this command:

pip install -r requirements.txt

requirements.txt 看起来像:

The requirements.txt looks like:

cffi==1.2.1
characteristic==14.3.0
ConcurrentLogHandler>=0.9.1
cryptography==0.9.1
...

我猜上面的命令意思是在requirements.txt中安装包.但是我不想让它指定版本，所以我把它改成这样:

I guess the above command means to install packages in requirements.txt.But I don't want it to specify the version,So I change it to this:

cat requirements.txt | while read line; do pip install ${line%%[>=]*} --user;done

安装密码学时，它给了我错误:

When install cryptography,it gives me the error:

build/temp.linux-x86_64-2.7/_openssl.c:12:24:fatal error:pyconfig.h:No such file or directory 
#include <pyconfig.h>

我不知道如何解决这个问题，我尝试了很多方法，但都失败了.我的系统是centos 7，python的版本是2.7.5(默认).此外，是否还有其他适用于大量 url 的 scrapy 框架.提前致谢

I don't know how to solved this , I have tried a lot of methods ,but failed. my system is centos 7, and the version of python is 2.7.5(default). Besides, Is there any other scrapy frame which is appliable for a large number of urls . Thanks in advance
