我安装了正确版本的 Bundler：

docker@f5990915a8ae:/usr/src/app$ bundler version
Bundler version 2.2.17 (2021-05-05 commit 69cbd6e10e)

但是当我运行 db:migrate 时，它似乎正在使用另一个：

Warning: the running version of Bundler (2.1.4) is older than the version that created the lockfile (2.2.17). We suggest you to upgrade to the version that created the lockfile by running gem install bundler:2.2.17.

这是我的应用程序 gem 环境：

RubyGems Environment:
  - RUBYGEMS VERSION: 3.1.2
  - RUBY VERSION: 2.7.1 (2020-03-31 patchlevel 83) [x86_64-linux-gnu]

这是安装的两个捆绑器版本：

home/docker/.gem/specifications/bundler-2.2.17.gemspec
usr/lib/ruby/gems/2.7.0/specifications/default/bundler-2.1.4.gemspec

如何让 db:migrate 使用正确的？

【问题讨论】：

标签： ruby-on-rails ruby bundler

【解决方案1】：

改成

bundle exec rake db:migrate

或在 Gemfile.lock 中更改捆绑器版本
