【问题描述】:
当我尝试启动我的 Rails 服务器时,我收到以下错误:
$ bundle exec rails s
Your Ruby version is 2.3.7, but your Gemfile specified ~> 2.3.8
我不明白为什么会这样,因为我使用 Homebrew 和 rbenv 都将 Ruby 设置为 2.3.8。 2.3.7是系统的ruby版本。我使用的是 Mac OS 10.14.4。
$ ruby -v

我在这里看不到任何让我认为它应该使用 2.3.7 的东西。
我不确定还可以尝试什么。
Bundler 如何决定使用哪个版本的 Ruby,以及如何将其配置为使用 rbenv 或我的自制 Ruby 安装?
【问题讨论】:
-
可能是你的shell缓存了旧的
bundle命令,尝试运行hash -r。 -
不幸的是,我设法解决了我的问题,但没有确定真正解决了什么问题。如果有人开始获得多数赞成票,我会留下这个问题并接受答案。
-
我尝试了@matt 建议的方法,它有效! geeksforgeeks.org/hash-command-in-linux-with-examples
-
@matt 请添加它作为答案 - 它对我有用,我想投票。
