Question

我无法在 Heroku 上部署我的应用程序，并且每次尝试将我的代码推送到 Heroku 时都会收到以下错误。

首先，我使用命令 heroku create 创建了我的 Heroku 应用程序。然后我将所有修改过的文件添加并提交到 git 暂存区，最后当我尝试使用 git 推送到 Heroku 时，它在构建后部分失败。

我用于推送代码的命令：git push heroku master

我遇到的错误：

您也可以尝试在推送中不包含 node_modules 文件夹。

还尝试通过 heroku web 和 github repo 推送它

Answer 2

根据错误日志，axios 软件包未作为依赖项安装在您的 package.json 中。

可能您已经在设备上全局安装了 Axios，因此它可以在本地运行，但在 Heroku 部署期间，它无法找到该依赖项。

所以通过运行命令安装它：

npm install axios

然后再试一次。如果同样的问题仍然存在，请共享您的 package.json 文件。

难以将我的 MERN 应用程序部署到 Heroku
