传递头文件/库后,没有构建Python 2.7.3 _sqlite3模块

2019年8月4日 179次阅读

我们需要启动一个Django项目,不能为持久性存储构建sqlite.

默认情况下,系统中未安装sqlite3-dev headers / libs
我在这个盒子上没有root权限(我们希望安装我们需要的所有权限)
我在/ opt / python / current2中编译/安装了Python-2.7.3
我在/ home / olib / sqlite-autoconf-307150中下载并编译了sqlite3源代码
我下载了pysqlite-2.6.3
我修改了pysqlite-2.6.3 / setup.py来指向我的sqlite3源头文件和库文件

include_dirs = ['/home/olib/sqlite-autoconf-3071501']  
library_dirs = ['/home/olib/sqlite-autoconf-3071501/.libs']

出于某种原因“_sqlite.so”已构建但不是“_sqlite3.so”当然这会导致Django导入失败

File "/opt/python/current2/lib/python2.7/site-packages/django/db/backends/sqlite3/base.py", line 31, in <module>
raise ImproperlyConfigured("Error loading either pysqlite2 or sqlite3 modules (tried in that order): %s" % exc)
django.core.exceptions.ImproperlyConfigured: Error loading either pysqlite2 or sqlite3 modules (tried in that order): No module named _sqlite3

最佳答案 重建Python

./configure --prefix=/opt/python/ LDFLAGS='-L/home/olib/sqlite-autoconf-3071501/.libs'     CPPFLAGS="-I/home/olib/sqlite-autoconf-3071501/'

./build/lib.linux-x86_64-2.7/_sqlite3.so现在已创建！
复制到lib-dynload目录

olib:~/Python-2.7.3> cp ./build/lib.linux-x86_64-2.7/_sqlite3.so /opt/python/current2/lib/python2.7/lib-dynload/

一切看起来都很好..
