我试图在服务器上使用rbenv来设置ruby，而不是安装了ruby和bundler的apt-get版本。

我遵循数字海洋指南，只在ruby版本(我需要2.7.1)和ruby安装路径(PREFIX=~/local ./ruby-build/install.sh)上偏离，因为我不是根用户，所以所有东西都保存在我的主文件夹中。

什么起作用了

安装rbenv
安装ruby构建
rbenv install 2.7.1
rbenv shell 2.7.1
rbenv global 2.7.1
bundle install
sudo apt-get purge ruby

但是，bundle exec rake没有运行，并返回以下错误：

/usr/bin/env: ‘ruby2.7’: No such file or directory

$ rbenv exec bundle exec ruby -v
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-linux]

$ rbenv exec bundle exec rake
Your Ruby version is 2.7.0, but your Gemfile specified 2.7.1

当我简单地在我的应用程序文件夹中运行rake时(没有经过bundle exec)，我会得到以下错误：

$ rake
rake aborted!

它看起来像是运行rbenv exec bundle exec rake [command] actually调用 /usr/local/bin/bundle而不是rbenv的shim，尽管.rbenv/shims和.rbenv/bin在PATH中是第一位的。

知道为什么吗，以及如何解决这个问题？

我已经尝试过了，

gem update --system
rbenv rehash
完全拆卸和重新安装rbenv
通过rbenv安装ruby 2.7.0

这是我的环境：

$ echo $PATH
/home/gchampenois/.rbenv/shims:/home/gchampenois/.rbenv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

$ lsb_release -a | grep 'Description'
Description:    Ubuntu 20.04.2 LTS

$ rbenv versions
* 2.7.1 (set by RBENV_VERSION environment variable)

$ which -a bundle
/home/gchampenois/.rbenv/shims/bundle
/usr/local/bin/bundle
/usr/bin/bundle
/bin/bundle

$ which -a gem
/home/gchampenois/.rbenv/shims/gem

$ which -a ruby
/home/gchampenois/.rbenv/shims/ruby

$ ruby -v
