今天把本地运行OK的scrapy爬虫程序捣鼓到服务器上运行，结果报了以下错误
2018-10-11 19:00:19 [twisted] CRITICAL: Unhandled error in Deferred:
2018-10-11 19:00:19 [twisted] CRITICAL:

ModuleNotFoundError: No module named '_sqlite3'
网上搜说sqlite3模块没有，需要安装并重新编译，然而网上各种方式都无效，好坑，最后在stackoverflow上找到个有效的方式
第一步安装 sqlite-devel
第二步 cd到python3源码目录 运行./configure --enable-loadable-sqlite-extensions && make && sudo make install
