我在推送到 heroku 时收到以下错误消息：

这是我的 package.json（如果你想知道我已经在本地安装了依赖项并且 package.json 有效）

【解决方案1】：

问题出在 git add 上。我忘记添加 node_modules 文件。我关闭了终端并再次运行 Heroku 和 NodeJs 入门 [1] 中给出的命令集。应用程序已成功推送到堆栈。

【讨论】：

但我认为您不应该将 node_modules 签入 git 吗？运行“npm install”时，NPM 应该安装依赖项？？
@conor909：是的，我希望节点模块也不需要被推送到heroku，但如果你看到这里的步骤devcenter.heroku.com/articles/…，这正是它所说的。也许有人可以澄清节点模块是否需要推送到 git 和 heroku。
