使用第三方ruby库在我的葫芦测试，但得到错误

Question

我的葫芦安卓测试项目有以下结构:

-- myApp.apk
-- features (directory)
          |-- my-feature-1-file-name.feature
          |-- step_definitions (directory)
          |      calabash_steps.rb
          |-- support (directory)
          |      thirdPartyLib.rb

我的葫芦测试步骤需要使用第三方库thirdPartyLib.rb。正如你上面看到的，在features/目录下，我有一个support/目录，在那里，我有一个thirdPartyLib。 ruby file.

内的 thirdPartyLib。rb，第一行代码如下:

require 'jmespath'
...

当我去到我的项目根，并运行calabash-android run myApp.apk DEBUG=1命令测试，我得到以下错误:

DEBUG: Setting Android SDK location to $ANDROID_HOME
DEBUG: Android SDK location set to '/Users/John/Library/Android/sdk'

/Users/John/my-calabash-test/features/support/thirdPartyLib.rb:1:in `<top (required)>'
...

所以，这是一个加载错误，它看起来像葫芦-android不能加载文件jmespath (LoadError)声明在thirdPartLib。rb 。怎样才能消除这个错误呢?

Answer 1

您需要安装jmespath gem才能使用它。要安装它，你需要将它添加到你的gemfile中。你可以像下面这样指定gem的本地副本

gem "foo", :path => "/path/to/foo"

取自这个问题/答案的例子-我如何在我的Gemfile中指定一个本地gem ?
