To update to the latest version installed on your system, run `bundle update --bundler`.
To install the missing version, run `gem install bundler:1.17.2`
Avec cela, j'ai frappé l'un des éléments suivants.
bundle update --bundler
gem install bundler:1.17.2
Cela m'a gêné pendant que je faisais diverses choses.
-> % bundle install

Your Ruby version is 2.7.1, but your Gemfile specified 2.6.3
Il y avait de nombreux articles qui semblaient être parce que les versions que j'ai recherchées et auxquelles je faisais référence étaient différentes, mais dans mon cas Gemfile
ruby '2.7.1'
Je devais juste le réécrire. bundle install fonctionne maintenant.
Vient ensuite la mise à niveau de la version de Rails C'est aussi un Gemfile
gem 'rails', '~> 6.0.3', '>= 6.0.3.3'
Ensuite, vous pouvez y aller si vous faites budle install.
-> % bundle install

The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

Resolving dependencies...
Bundler could not find compatible versions for gem "activesupport":
In snapshot (Gemfile.lock):
activesupport (= 5.2.4.3)
In Gemfile:
rails (~> 6.0.3, >= 6.0.3.3) was resolved to 6.0.3.3, which depends on
activesupport (= 6.0.3.3)
web-console (>= 3.3.0) was resolved to 3.7.0, which depends on
railties (>= 5.0) was resolved to 5.2.4.3, which depends on
activesupport (= 5.2.4.3)
Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
J'ai été grondé.
bundle update
fais le
bundle install
Ensuite, j'ai pu y aller.
