Erreur lors de l'installation de Cocoapodes - Macos BigSur

J'apprends comment programmer et j'essaie d'installer des cocoapodes, mais je reçois une erreur avec Sudo gem install cocoapods.

C'est ce que je reçois:

    Building native extensions. This could take a while...
ERROR:  Error installing cocoapods:

Je sais qu'il y a une ligne où il est dit "Vous devez d'abord installer des outils de développement", et au début c'était vrai. J'ai ensuite installé les outils de ligne de commande Xcode (je devais le télécharger manuellement de Apple Developer parce que le xcode-select --install la ligne n'a pas fonctionné) et a essayé d'installer des cocoapodes à nouveau. Mais je reçois la même erreur, même après le redémarrage.

Il a également la route pour le journal, et c'est ce qu'il dit:

Alors, je suis coincé. J'utilise actuellement Macos Big Sur Beta 9 et Xcode 12.0.1 (non-bêta).

J'ai eu le même problème (Catalina 10.15.7 & XCode 12.3).

J'ai utilisé homebrew au lieu de la gemme:

brew install cocoapods

J'ai fait face au même problème

Correction par la mise à niveau Ruby Version à 2.7.2. Crédits pour https://stackoverflow.com/a/65033418/4982169

J'utilise rbenv pour gérer Ruby versions.
