Question

最初，我无法通过此安装宝石。

$ gem install jekyll 
ERROR:  Error installing jekyll:
invalid gem: package metadata is missing in /usr/local/rvm/gems/ruby-1.9.3-p392/cache/fast-stemmer-1.0.2.gem

然后一些指南建议使用sudo，所以我使用了

$ sudo gem install jekyll

表示已安装，但随后......

Successfully installed jekyll-2.5.3
Parsing documentation for jekyll-2.5.3
Done installing documentation for jekyll after 1 seconds
1 gem installed

$ jekyll -v

from /Users/vincentchin/.rbenv/versions/2.2.2/bin/jekyll:22:in `<main>'

我猜测通过运行sudo安装版本，我需要一个不同的命令或路径才能访问gem？或者它安装的位置可能无法被尝试执行的任何内容识别？

我已经查找过其他人在安装Jekyll时遇到问题的其他案例，并且遇到了一些我无法理解的研究。所以如果需要这些信息来调查我的问题......

Answer 1

你有两个ruby版本，试试看：

bundle exec jekyll -v

Answer 2

我卸载了所有内容（rvm和rbenv）并清理了卸载时没有获得的任何剩余文件，并使用ruby重新安装了rvm stable。

从那里我可以使用

安装

gem install jekyll

从那里一切顺利。

我想在我开始时的某个时刻，我安装了一堆东西而不知道它们的用途（rbenv和rvm，应该只有两个中的一个）。

在sudo gem install之后无法访问Jekyll
