在heroku上找不到模块'socket.io‘

Question

我已经研究了这个问题，但我还不能处理。

我的带有node和socket.io的简单应用程序在我的本地计算机上运行得很好，但在heroku上就不行了。

package.json中包含Socket.io

我运行'heroku run bash‘并列出了安装在heroku上的node_modules，但socket.io不在那里。但在我本地的电脑上，socket.io似乎已经安装了。

我'heroku销毁我的应用‘，然后重新创建它。我运行了几次以下脚本

git add .
git commit -am "comment"
git push heroku master

如何让heroku安装socket.io模块？顺便说一句，我不确定这是否是真正的问题。

有什么线索吗？

非常感谢。

你有没有尝试过在你的依赖中用*替换latest？

Answer 2

我找到了一个适合我的solution。

它说从.gitignore文件中删除node_modules文件夹，这样你就可以将它们推送到heroku。

但这并不完全是我想要的。在某种程度上，heroku应该自动完成此安装，因为socket.io是在package.json中。我不明白为什么它只跳过socket.io。
