这个 Cucumber 错误信息是什么意思? [英] What does this Cucumber error message mean?

问题描述

我运行 cucumber features 并得到:

Using the default profile...

can't activate builder (~> 2.1.2, runtime) for 
    ["activemodel-3.0.5", "actionpack-3.0.5", "railties-3.0.5"],
already activated builder-3.0.0 for
    ["cucumber-0.10.2"] (Gem::LoadError)

这里出了什么问题，我该如何解决?谢谢.

What is wrong here and how can I fix it? Thanks.

推荐答案

这意味着你已经安装并加载了builder 3.0.0，而rails需要2.1.x.

It means you have builder 3.0.0 installed and loaded while rails needs 2.1.x.

试试

$ gem 卸载构建器

紧随其后

$ 包

(假设您使用的是捆绑程序).

(assuming you're using bundler).

如果你不是，做

$ gem install builder --version "<2.2"

HTH.
