我是 Rails 新手。在 Linux mint 16 上使用 RoR。捆绑安装似乎给我带来了一些问题。产生此错误的命令列表： gem install bundler、bundle install --without production、bundle update、gem install pg或任何gem install <insert_gem_here> （已删除下面的超链接）

调用 Psych 可能是因为在您的项目中您使用环境变量或YAML文件，并且其中一个存在语法错误。

检查这些文件：

~/.bashrc 
~/.profile
~/.bash_profile

config/dababase.yml

如果其中一个有语法错误，则它正在捕获输出。我有类似的问题并修复了~/.profile错误，一切都很好！
