pyconfig.h 在“pip 安装加密"期间丢失; [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
...
我猜上面的命令是在requirements.txt中安装packages.但是我不想它指定版本,所以我改成这样:
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
安装加密时,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).另外,有没有其他scrapy框架适用于大量url.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
