Python 在Linux上启动新安装的web2py时出现异常

在Linux Redhat 64位（Python 2.7.3）上解压缩web2py最新源代码后，我启动服务器，第一个调用生成以下堆栈跟踪：

Anyone can help please?

这个问题与Python安装中缺少sqlite3有关

---

使用该库重新编译Python修复了问题。

在此学习如何格式化代码（将异常格式化为代码）。我们可能还需要一些代码。是的，在第三次尝试时这样做了：）我没有代码要显示，这是web2py开箱即用。可能重复：。我似乎觉得它找不到安装的任何数据库驱动程序包。您计划使用哪个数据库后端？SQLite至少应该是可用的（Python标准库附带）。另请参阅：。我知道这个问题，但它没有回答我的问题。。。现在我正在调查，因为在我的python安装中（我没有这样做），sqlite3似乎丢失了（导入sqlite3会给出一个异常）。python安装没有

sqlite3

包的事实确实是异常的，这可以解释错误。在我的Ubuntu安装中，它肯定是基本

python-2.7

包的一部分。
