Question

我试图安装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

它正确编译它，但之后我想安装bundler ..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/lib/ruby/1.9.1/psych.rb:203:in `parse_stream'

    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 ..但是，即使是构建也不会完成类似的错误，也依赖于这个心理翻译...... :(

我无法在网上找到有相同问题的内容，所以我问......

我尝试了那两个没有帮助我的资源，好像rbenv安装程序正在自动执行此操作

Installing libyaml for ruby on a mac osX (Lion)

Fixing the "ruby installation is missing psych" error?

有人有建议吗？提前谢谢..

Answer 1

当我的.gemrc或.irbrc中出现YAML语法错误时，我看到过这样的错误。

检查/删除它们，然后重试。

Answer 2

我们的 .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 保留在原位。然后重新安装1.9.3p392没有任何问题。基本上是一个YAML解析器问题。

完整的 .gemrc ：

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

Answer 3

从

更改gem.rc文件

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

到

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

Answer 4

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

更改为：

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