Question

我正在使用Ionic 2尝试让Firebase基于this tutorial工作，但使用Ionic rc4。任何帮助表示赞赏。

require 'optparse'

options = {}
OptionParser.new do |opts|
  opts.on("-t T", "arg t") do |t|
    options[:t] = t
  end

  opts.on("-y Y", "arg y") do |y|
    options[:y] = y
  end
end.parse!

p options

###

ruby temp.rb -t 1 -y 2
{:t=>"1", :y=>"2"}

没有编译错误，但我收到以下运行时错误：

Answer 1

转换为答案：您的模板中有一个标记，该标记无法通过解析器，该标记为

<h7>

将其更改为

<h3>

例如，它应该工作（或者将它放在div中并根据需要使用CSS类设置它）。

Answer 2

h7标记只是在HTML 5中存在。这是您的错误。这不是离子或火基误差。只需为h6或其他标签更改h7，此错误将消失
