CentOS 7上安装Scrapy报错,提示说Twist构建失败,另外找不到python.h头文件目录。
#pip install scrapy

----------------------------------------
Command "/usr/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-install-ci6F35/twisted/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-record-I2xt6r/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-install-ci6F35/twisted/
看到“fatal error: Python.h: No such file or directory #include "Python.h"”这句话,我猜就是缺少python开发包了。但却有不知道python开发包在yum中叫什么名字
一番google之后,记在这里吧:
Ubuntu上可以执行
apt=get install python3.6-dev
Centos7上可以执行
yum install python3.6-devel
完成之后再次执行pip install scrapy,成功。
All Done!!!
