ruby-on-rails - cap deploy:migrations: 错误:第 1 行第 1 列不允许使用控制字符(Psych::SyntaxError)

Question

请看下面的错误(control characters are not allowed at line 1 column 1 (Psych::SyntaxError))并帮助我解决它。当我尝试在Ubuntu 12.10 ruby 1.9.3 Rails 3.2.0。有用于部署的本地 Apache 服务器。

我在 stackoverflow 上尝试了不同的解决方案，但没有人解决问题。

提前致谢

我上周遇到了同样的问题，我用这个解决了

“这是你的钩子(Hook)/home/rails/.rvm/hooks/after_use_textmate - 禁用它 (chmod -x) 并且 rvm 将不再为它生成包装器。”
