rbenv - Ruby - 如何在多个项目之间切换 ruby​​ 版本

Question

我使用 rbenv 安装了 Ruby。我正在使用 Mac。对于我的一个项目，我使用的是 ruby​​ 2.6.3。对于我的另一个项目，我需要 ruby​​ 2.7.4。所以我安装了这两个版本。

在我的第一个项目中，如果我使用 rbenv 版本，它会正确显示

   system
   * 2.6.3 (set by /Users/suganyas/academics/project1/.ruby-version)
    2.7.4

对于我的第二个项目，我使用命令设置 ruby​​ 版本 2.7.4

rbenv local 2.7.4

因此，如果我从第二个项目中执行 rbenv 版本，它会再次显示，

  system
  2.6.3
  * 2.7.4 (set by /Users/suganyas/project2/ceep/.ruby-version)

但是当我进行捆绑安装时，我收到以下错误

  Your Ruby version is 2.6.3, but your Gemfile specified 2.7.4

运行以下命令帮助我选择了正确的 rbenv 本地版本

echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
source ~/.bash_profile
