Question

我所做的只是按照Jekyll网站上的说明进行操作。我收到一个错误，我不知道如何修复。

~ $ gem install jekyll
~ $ jekyll new my-awesome-site
~ $ cd my-awesome-site

当我收到错误时：

error: undefined method `gsub' for nil:NilClass. Use --trace to view backtrace

跟踪结果：

/Users/rruiz/.rvm/gems/ruby-1.9.3-p392/gems/jekyll-1.1.2/lib/jekyll/stevenson.rb:77:in `message': undefined method `gsub' for nil:NilClass (NoMethodError)

如何解决这个问题让Jekyll工作？

Answer 1

给Jekyll一个无效命令时，我得到了同样的错误。

> jekyll foo
/.rvm/gems/ruby-2.0.0-p247/gems/jekyll-1.1.2/lib/jekyll/stevenson.rb:77:in `message': undefined method `gsub' for nil:NilClass (NoMethodError)


> jekyll build
Configuration file: .../projects/my-awesome-site/_config.yml
            Source: .../projects/my-awesome-site
       Destination: .../projects/my-awesome-site/_site
      Generating... done.

你想要运行什么命令？

jekyll build构建项目（-w以观察更改）

jekyll serve启动服务器

错误：未定义的方法`gsub'代表nil：NilClass
