cap deploy抛出“ Ruby版本是2.2.5，但您的Gemfile指定了2.5.3”，但我的Ruby版本是2.5.3

Question

一无所获（毫不夸张：我在此异常开始发生前两个小时就部署了），cap production deploy停止工作并抛出此错误：

Your Ruby version is 2.2.5, but your Gemfile specified 2.5.3
bundle stderr: Nothing written

除了我正在使用gemfile和.ruby-version中指定的2.5.3。

这是我的gemfile中的内容：

source 'https://rubygems.org'

ruby '2.5.3'

我正在使用rvm。 ruby -v返回ruby 2.5.3p105 (2018-10-18 revision 65156) [x86_64-darwin18]，并将ruby设置为global。我尝试先运行gem update bundler，gem install bundler，然后运行bundle install，bundle，然后删除gemfile.lock。

$ bundle env

编辑：$ gem env的输出：

我正在使用AWS。 bundle exec cap production deploy会引发相同的错误。
