在 dockerfile 中使用 apt get 安裝適當版本的 ruby​​-bundler

Question

如何安裝與我嘗試將我的應用程序更新到的 Ruby 版本配套的適當捆綁程序版本？

dockerfile 中的上一個命令apt-get install -y ruby3.5 ruby3.5-dev ruby-bundler

修改 dockerfile apt-get install -y ruby3.6 ruby3.6-dev ruby-bundler

當我運行 dockerfile 並嘗試運行bundle install時，我收到此錯誤。 我也不確定sprockets錯誤是否是由於捆綁器已過時。

Warning: the running version of Bundler is older than the version that created the lockfile. We suggest you upgrade to the latest version of Bundler by running `gem install bundler`.

You have requested:
  sprockets = 3.0
The bundle currently has sprockets locked at 2.0
Try running `bundle update sprockets`
If you are updating multiple gems in your Gemfile at once,
try passing them all to `bundle update`

如果您需要更多控制，我建議您不要從 deb package 安裝它，而是通過gem install 。 就像是：

FROM <whatever>

ENV RUBYGEMS_VERSION=3.1.2 \
    BUNDLER_VERSION=2.3.9

RUN apt-get update && \
    apt-get -y install <prerequisites, ruby, ...> && \
    gem update --system ${RUBYGEMS_VERSION} && \
    gem install bundler --version ${BUNDLER_VERSION} \
...
