ruby - Rails 3 不会用 rvm 安装 sqlite3-ruby gem？

Question

我正在试用 rvm，并用它安装了 ruby​​ 1.9.2 和 rails 3。我需要重新安装 sqlite3-ruby gem(因为 rvm 为不同版本的 ruby​​ 将所有 gem 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

我真的不太清楚该怎么做...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)它没有也不要安装在 ruby​​ 1.8.7 环境中。

rvm 破坏了 gem 吗？新 gem 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，我得到了同样的错误，但随后看到我的 gem 列表中列出的 sqlite3-ruby(不确定它是否以某种方式恢复从备份，或安装尽管有错误)

我会投票赞成或评论布伦南的回答，但我还没有足够的分数来做这件事。我想我会留下这个答案，以防它对其他人有帮助:我在这个上面花了一段时间......我安装了 Ruby 1.9.1 和 Rails 3.0.3 并且可以正常工作，但决定转向 RVM。根据说明安装了 RVM，然后再次安装 rails，所有肉汁......然后尝试捆绑安装并使用 sqlite3 遇到此错误:

sqlite3 is missing. Try 'port install sqlite3 +universal'
or 'yum install sqlite3-devel' and check your shared library search path (the
location where your sqlite3 shared library is located).
*** 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.

我知道我之前的配置中使用过 SQLite3，所以我去找了原来的目录。这是 usr/local/sqlite3

我尝试将其用作 --with-sqlite3-dir= 路径，但没有奏效。然后我只是为了好玩:

gem install sqlite3-ruby -- --with-sqlite3-dir=/usr/local/lib

无论出于何种原因，这都有效。所以，以防万一有人
