[RUBY] Erreur lors de l'installation du bundle après la mise à niveau vers Catalina

contenu de l'erreur

$ bundle install
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

(réduction)

An error occurred while installing ffi (1.13.0), and Bundler cannot continue.
Make sure that `gem install ffi -v '1.13.0'` succeeds before bundling.

In Gemfile:
  guard-rspec was resolved to 4.7.3, which depends on
    guard was resolved to 2.16.2, which depends on
      listen was resolved to 3.2.1, which depends on
        rb-inotify was resolved to 0.10.1, which depends on
          ffi

Ce que j'ai essayé

$ gem install ffi -v '1.13.0'  
Building native extensions. This could take a while...
ERROR:  Error installing ffi:
        ERROR: Failed to build gem native extension.
...

Même si la commande est exécutée en fonction de l'erreur, une erreur se produit

$ xcode-select --install                             
xcode-select: error: command line tools are already installed, use "Software Update" to install updates

Il était déjà installé.

Solution

$ sudo xcodebuild -license accept   

Résolu quand j'ai exécuté.
