エラーログを確認してみた。yarn古い。アップデートするかチェックをdisableにしろと言われる。

下記を実行してみたが同じエラーが出る。webpacker.xmlのcheck_yarn_integrityもfalseにしても同じ。

yarn install --check-files

思いつく限りの削除を試みる。それでも同じエラーが出る。

rm yarn.lock
rm -rf node_modules
yarn install
yarn upgrade
yarn install --check-files
bundle install
bundle update
rails webpacker:install 

よくよく見てみたらconfig/webpakcer.xmlのdefault以外にもdevelopmentでcheck_yarn_integrityが定義されていた。
