我正在尝试rvm,并安装了
ruby 1.9.2和rails 3.我需要重新安装sqlite3-ruby gem(因为rvm保留所有gem为不同版本的ruby分开).
问题是,当我尝试时,我得到：
gem install sqlite3-ruby /home/jenny/.rvm/rubies/ruby-1.9.2-p0/bin/gem:4: warning: Insecure world writable dir /home/jenny/.rvm/gems/ruby-1.9.2-p0/bin in PATH,mode 040777 Building native extensions. This could take a while...

我真的不太清楚要做什么…我之前已经在这台机器上安装了sqlite3-ruby(使用rails 2.3.5)当我尝试重新安装这个gem(使用rvm系统设置)时,它没有安装在ruby1.8.7环境中,EITHER.
rvm打破了宝石吗？新宝石是否与我的操作系统不兼容(我正在运行opensuse linux)
编辑：当我尝试在我的常规ruby环境中重新安装(卸载而不是再次安装)sqlite3-ruby时,我得到了相同的错误,但是后来看到我的gem列表中列出的sqlite3-ruby(不确定它是否以某种方式从备份恢复,或安装尽管有错误)
你可以试试
原文链接：https://www.f2er.com/sqlite/197608.htmlgem install sqlite3-ruby -- --with-sqlite3-dir=/path/to/your/sqlite3
如果这不起作用,你可能会尝试update your sqlite3,3.6.4相当陈旧,我认为较新版本的Ruby sqlite存在旧问题.
(最可能的原因是你得到两个不同的答案是版本2和3之间是一个重大变化 – 我相信大多数处理Unicode,而且有些程序仍使用2,而不是3).
