我试图卸载 rvm 以便在我的 Mac 上使用 rbenv。一切正常，直到红宝石发挥作用..

使用时

rbenv install 1.9.3-p194

它可以正确编译，但之后我想安装捆绑器..这会产生以下错误

computer:~ computer$ gem install bundler
/Users/computer/.rbenv/versions/1.9.3-p194/lib/ruby/1.9.1/psych.rb:203:in `parse': (<unknown>): mapping values are not allowed in this context at line 1 column 34 (Psych::SyntaxError)

    from /Users/computer/.rbenv/versions/1.9.3-p194/bin/gem:21:in `<main>'

然后我尝试安装旧版本的 ruby​​ 1.9.3-p125 .. 但即使构建也无法完成同样依赖于这个心理解释器的类似错误...... :(

我在网上找不到有相同问题的东西，所以我问..

我尝试了这两个对我没有帮助的资源，好像 rbenv 安装程序正在自动执行此操作

在 mac osX (Lion) 上为 ruby​​ 安装 libyaml

修复“ruby 安装缺少心理”错误？

有人有建议吗？提前致谢..

当我的 .gemrc 或 .irbrc 中出现 YAML 语法错误时，我看到过类似的错误。

检查/删除它们，然后重试。

我们在.gemrc中遇到了同样的问题。删除.gemrc解决了这个问题。--文件开头有2 个破折号。将它们更改为---（3 个破折号）并将.gemrc留在原处。然后重新安装1.9.3p392没有任何问题。基本上是 YAML 解析器问题。

完整的.gemrc：

---
gem: --no-ri --no-rdoc

更改 gem.rc 文件从

install: --no-rdoc --no-ri
update: --no-rdoc --no-rigem: --no-document

至

install: --no-rdoc --no-ri
update: --no-rdoc --no-ri

install: --no-rdoc --no-ri
update: --no-rdoc --no-rigem: --no-document

改成：

install: --no-rdoc --no-ri
update: --no-rdoc --no-ri
gem: --no-document

为了保留更快的 Gem 安装选项
