Question

我在网络上搜索过，但无法找到解决此错误的方法。每当我尝试启动rails服务器，甚至是rails console时，我都会得到crack/xml (LoadError)。任何人都有任何他们认为可以帮助我正常运行的建议吗？

我试图安装crack gem然后运行bundler但是即使重启终端后我仍然会遇到同样的错误。所以我不确定如何解决这个问题。

Answer 1

我得到了@apneadiving解决方案。

我也试过替换

gem 'ap'

与

gem 'awesome_print'

Gemfile中的

。

这似乎也有效。

更新：似乎ap可能是awesome_print gem的html / xml版本。

Answer 2

可以肯定的是：错误源于ap gem，this line。

它使用crack / xml作为依赖，但是它没有被声明为gemfile中的依赖关系。子捆绑器无法知道它应该被添加。

如何解决？

在宝石文件中添加宝石crack，在ap宝石
或更改ap gem源代码

无法启动Rails服务器或控制台 - （crack / xml）LoadError
