"rails server"不起作用，找不到sqlite3_native符号

Question

当我尝试"rails server"命令时，我收到了这个错误消息。。。不确定发生了什么？

/Library/Ruby/Gems/1.8/gems/sqlite3-1.3.5/lib/sqlite3/sqlite3_native.bundle: dlsym(0x1010621e0, Init_sqlite3_native): symbol not found - /Library/Ruby/Gems/1.8/gems/sqlite3-1.3.5/lib/sqlite3/sqlite3_native.bundle (LoadError)

Answer 1

您是否尝试过重新安装'sqlite3-ruby'gem？

正如SO的回答所指出的那样，您的系统中可能存在一些sqlite-ruby接口问题，即Rails 3（beta 4）安装后的Sqlite3错误。

此外，如果对ruby 1.8没有任何特定要求，您应该使用rvm/rbevn和ruby 1.9。
