當我在本地運行heroku local時，它工作正常，但heroku open將我引向這些錯誤。

可能是Heroku使用的Node版本的問題。你可以試試setting Heroku to use the same one you use locally。另外，在部署到Heroku之前，您不需要執行npm install，因爲它在部署時會適合您（因此不要在git上包含node_module文件夾）。

我注意到在我的'.gitignore'中，我包含了node_modules。也許，我需要排除它呢？ – Alejandro

我認爲這將是好的 – andresk

（你希望節點模塊安裝在他們將要運行的環境中） – andresk
