How to use bundler 2.x with Docker

You would get an error if there is bundler's version difference between BUNDLED WITH in Gemfile.lock and the installed bundler.

https://dev.to/tanakaworld/how-to-resolve-you-must-use-bundler-2-or-greater-with-this-lockfile-2pf7

You can resolve the issue by followings.

Update the gem in image gem update --system
Install any version bundler gem install bundler -v <version>

Example:

FROM ruby:2.6.2

ENV APP_HOME /app
WORKDIR $APP_HOME

COPY Gemfile $APP_HOME/Gemfile
COPY Gemfile.lock $APP_HOME/Gemfile.lock

ENV BUNDLER_VERSION 2.1.0
RUN gem update --system \
    && gem install bundler -v $BUNDLER_VERSION \
    && bundle install -j 4

COPY . $APP_HOME

How to resolve "You must use Bundler 2 or greater with this lockfile"

I've written the same article in Japanese.

bundler 2.x has been released on Jan 4th 2019.

BUNDLED WITH in Gemfile.lock is rewritten when you run bundle update with bundler 2.x in your machine.



$ bundle update
•••

$ git diff
•••
 BUNDLED WITH
-   1.17.3
+   2.0.1

This change would make some problems on CircleCI and production environment etc.

You must use Bundler 2 or greater with this lockfile.

Solution A: Downgrade the bundler

Check the current version



$ cat Gemfile.lock | grep "BUNDLED WITH" -A 1

BUNDLED WITH

2.0.1

Recreate Gemfile.lock with the older version



$ gem install bundler -v 1.17.3

$ rm Gemfile.lock

$ bundle 1.17.3 install

Confirm



$ cat Gemfile.lock | grep "BUNDLED WITH" -A 1

BUNDLED WITH

1.17.3

Solution B: Change the bundler version in the environment.

Set any version as BUNDLER_VERSION
Reinstall the bundler



version: 2

jobs:

  build:

    docker:

      # specify the version you desire here

      - image: circleci/ruby:2.6.0-node-browsers

        environment:

          # 1

          BUNDLER_VERSION: 2.0.1

  # Specify service dependencies here if necessary
  # CircleCI maintains a library of pre-built images
  # documented at https://circleci.com/docs/2.0/circleci-images/
  # - image: circleci/postgres:9.4

working_directory: ~/repo

steps:
  - checkout

  # 2
  - run:
      name: setup bundler
      command: |
        sudo gem update --system
        sudo gem uninstall bundler
        sudo rm /usr/local/bin/bundle
        sudo rm /usr/local/bin/bundler
        sudo gem install bundler

  # •••

  - run:
      name: install dependencies
      command: |
        bundle install --jobs=4 --retry=3 --path vendor/bundle

How to customize the Notification in CKEditor

Premises

ckeditor5-vue

Customize it via `extraPlugins`

According to documentation, you can customize notification's behavior like this.

<template>
  <ckeditor :config="editorConfig" />
</template>

<script lang="ts">
import Vue from 'vue';
import CKEditor from '@ckeditor/ckeditor5-vue';
import ClassicEditor from '@ckeditor/ckeditor5-build-classic';


export default Vue.extend({
  components: {
    ckeditor: CKEditor.component,
  },
  data() {
    return {
      editorConfig: {
        extraPlugins: [
          editor => {
           const notifications = editor.plugins.get('Notification');
           notifications.on('show:warning', (evt, _data) => {
             evt.stop();
           });
          };
        ],
      },
    };
  },
});
</script>
