run bundle install 时出错

新建 rails 应用时，报错，（ruby 1.9.3p0，Rails 4.0.0）

Gem::RemoteFetcher::FetchError: SocketError: getaddrinfo: Name or service not known (https://rubygems.org/gems/sqlite3-1.3.9.gem) An error occurred while installing sqlite3 (1.3.9), and Bundler cannot continue. Make sure that gem install sqlite3 -v '1.3.9' succeeds before bundling. fengwei@fengwei-Aspire-4745G:~/rubyprojects$ gem install sqlite3 ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions into the /var/lib/gems/1.9.1 directory.

看到“Make sure that gem install sqlite3 -v '1.3.9' succeeds before bundling.”这一句时我以为是 sqlite3 木有安装好，结果我敲了：sqlite3 --version 发现是有安装的，版本信息为：3.7.15.2

木有其他用户的啊，怎么会没有权限勒，有遇到相同问题的吗，求解？？

Can't mass-assign protected attributes: phone

提交数据的时候报错：Can't mass-assign protected attributes: phone

之前的数据没有问题，用 scaffold 生成的，后来插入一个 phone:string

然后：rake db:migrate

在网页表单里提交 phone 的数据时就报这种错误了，请教各位错误出在哪里？怎么修改？

附上我的版本：Rails 3.2.13 ruby 1.9.3
