这是问题所在.添加Guard gem时,我打电话时一切都很好Guard.当我添加时Spork,我得到以下错误,这不会影响测试我的测试,但每次我尝试重新启动Guard时它都会启动它.

我有以下哈希:

hash = {'name' => { 'Mike' => { 'age' => 10, 'gender' => 'm' } } }

我可以通过以下方式访问年龄:

hash['name']['Mike']['age']

如果我使用Hash#fetch方法怎么办？如何从嵌套哈希中检索密钥？

正如塞尔吉奥所说,做到这一点的方式(不为自己创造一些东西)将是一系列fetch方法:

hash.fetch('name').fetch('Mike').fetch('age')

我通常会为不同的代码段创建分支,但偶尔会忘记创建一个新的分支,并且所有内容都发生在主分支上.

我怎么能说git虽然我在主分支上,但这个提交是针对xyz分支的？

你可能猜到,类img-circle会创建一个圆形图像.现在,当您尝试向该类添加边框时,它表现得很奇怪:它使图像成为带有截断边缘的正方形.它适用于Firefox和Chrome btw.
