我安装了RVM，然后用它安装了ruby-1.9.2，然后用rubygems安装了rails 3.0。它允许我创建一个新的应用程序，但是当我更改为应用程序的根目录并尝试生成脚手架时，我收到此错误:
Could not find gem 'sqlite3-ruby (>= 0, runtime)' in any of the gem sources.
Try running `bundle install`.
然后我运行了“bundle install”，一切看起来都安装得很好，直到它到达 sqlite3-ruby 并给了我这个巨大的错误消息:

有人知道是什么原因导致这些错误吗？ RVM？
最佳答案
不，这不是 RVM 的错。这意味着您没有安装 SQLite3 库。
/home/connor/.rvm/rubies/ruby-1.9.2-p0/bin/ruby extconf.rb
checking for sqlite3.h... no
sqlite3.h is missing. Try 'port install sqlite3 +universal' or 'yum install sqlite3-devel'
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
您需要安装 SQLite3 库和开发头文件才能编译和安装 SQLite gem。
