composer requireコマンドでバージョンが全然うまくいかない時の対処法
Problem 1 - Root composer.json requires weidner/goutte ^2.1 -> satisfiable by weidner/goutte[2.1.0]. - weidner/goutte 2.1.0 requires illuminate/support ^8 -> found illuminate/support[v8.0.0, ..., 8.x-dev] but these were not loaded, likely because it conflicts with another require.というエラーの対処法
