我正在通过Ruby on Rails教程(Michael Hartl)学习RoR。
当我添加到.gemrc
时sublime ~/.gemrc
(已安装Sublime Text),我只是检查,例如
gem -v
我得到了
Failed to load /home/gvyntyk/.gemrc because it doesn't contain valid YAML hash
顺便说一句:
gvyntyk@gvyntyk-r60:~$ ldconfig -p | grep libyaml
libyaml-0.so.2 (libc6) => /usr/lib/i386-linux-gnu/libyaml-0.so.2
当我添加.gemrc行时:
install: --no-rdoc --no-ri
update: --no-rdoc --no-ri
(当然,我不想安装文档)
我收到错误:
gvyntyk@gvyntyk-r60:~$ gem install rails --version 4.0.2

当我删除.gemrc
时,我没有那些麻烦,我可以安装Rails。
怎么了?

总结前面的所有评论,我也遇到了这个问题,它是.yml的语法问题,因此我建议您在任何yaml检查网页中检查您的代码,或尝试使用它并看看有什么解决您的问题。
就我而言,我的错误出在我的sidekiq.yml中:
:verbose: true
:concurrency: 25
:queues:
- [mailers, 7]
- [default, 5]
解决方案:
:concurrency: 25
:queues:
- [mailers, 7]
- [default, 5]
通过免费的heroku计划,您应该使用:
:concurrency: 1
:queues:
- [mailers, 7]
- [default, 5]
发现Heroku发出许多警报后,无论如何都会度过美好的一天!
