尝试在Ubuntu上安装Rails，但我在安装sqlite3-ruby时遇到了麻烦-显然找不到sqlite3.h。我可以找到的所有对该错误的引用都表明问题是:未安装sqlite3 header ，还是make找不到它们。在我看来，我已经解决了这两个问题，但仍然遇到同样的问题。
不知道这是怎么回事。版本不匹配，也许吗？这是Ubuntu 1.0.04.1上的ruby 1.8.7，sqlite 3.6.22-1，gem 1.3.5和sqlite3-ruby 1.3.1。

请注意，
/usr/include在参数列表中。david@li88-188:~$ ls -l /usr/include/sqlite3.h
-rw-r--r-- 1 root root 268351 2010-02-08 03:59 /usr/include/sqlite3.h
并注意该文件在那里。
最佳答案
就我而言，我必须安装libsqlite3-dev
sudo apt-get install libsqlite3-dev
