我可以生成迁移，但无法运行它.我不断收到以下错误消息
I can generate a migration but I cannot run it. I keep getting the following error message

It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.

我安装了 libyaml
I installed libyaml
rvm pkg install libyaml
然后重新安装ruby
rvm reinstall ruby-1.9.3-p286
但这没有帮助.
为什么我不断收到此错误消息的任何其他想法?
Any other ideas why I keep getting this error message?
谢谢.
推荐答案
您需要在您的系统上安装 libtool 包，否则 libyaml 将无法编译.对于 Ubuntu 尝试:
You need the libtool package installed on your system, otherwise libyaml won't compile. For Ubuntu try:
<代码>sudo apt-get 安装 libtool
rvm pkg 安装 libyaml
rvm pkg 安装 libyaml-dev
rvm 重新安装 1.9.3
您也可以简单地使用发行版的包管理器来安装库而不是 rvm.对于 Ubuntu:
Also you can simply use your distro's package manager to install the library instead of rvm. For Ubuntu:
<代码>sudo apt-get install libyaml libyaml-dev
