通过pip install pysqlite，

运行程序报错：

ImportError: /usr/local/python2.7/site-packages/pysqlite2/_sqlite.so: undefined symbol: sqlite3_stmt_readonly

于是nm/usr/local/python2.7/site-packages/pysqlite2/_sqlite.so | grepsqlite3_stmt_readonly

显示：

U sqlite3_stmt_readonly

说明_sqlite.so中的sqlite3_stmt_readonly函数要依赖其他的库。

于是ldd/usr/local/python2.7/site-packages/pysqlite2/_sqlite.so，

显示：

linux-vdso.so.1 => (0x00007fff467f1000)
libpython2.7.so.1.0 => /usr/local/python/lib/libpython2.7.so.1.0 (0x00007f9f8f621000)

其中与sqlite相关的只有libsqlite3.so.0 库，执行nm/usr/lib64/libsqlite3.so.0 | grepsqlite3_stmt_readonly，没有结果，说明问题出在sqlite版本上，可能当前的sqlite版本太老，没有提供sqlite3_stmt_readonly这个函数，并且查询到有文章中提到：

• The2.8.0version requires a "recent" sqlite version,at least 3.7.4,which is the first version to introduce the functionsqlite3_stmt_readonly,which is now required.
