  • 我一直在尝试将我的MERN应用程序上传到Heroku，并一直收到这些错误代码。Web应用程序将在我的本地主机上运行，但当我尝试将其上传到Heroku时，应用程序立即失败。我对使用MERN堆栈相对较新，正在尝试弄清楚如何正确地将应用程序上传到Heroku。*

对我来说，在检查了其他所有内容之后，问题出在空路径上。
不要使用空Path -->“/”部署API
总是给它一个给予这样的路径--> '/API/data'
空路径会让API认为favicon.ico是您试图传递的ID.
在我的情况下，例如我用途：
app.use（"/API/emps”，require（'./routes/employees. routes'））

我也面临着同样的问题（在本地运行良好，但在heroku上与我的MERN堆栈崩溃）;虽然我的编码与查询中提到的有点不同。然后我找到了一个页面，其中提到了大多数可能发生的原因（链接是https://dev.to/lawrence_eagles/causes-of-heroku-h10-app-crashed-error-and-how-to-solve-them-3jnl）。我也尝试了所有的方法，但对我来说都不起作用。但在评论部分，人们提到了代码中的以下更改
需要在命令模块“npm install serve --s”中运行这一行，然后将其复制到package.json中，就像“scripts”一样：{“dev”：“react-scripts start”，“start”：“serve -s build”，“build”：“react-scripts build”，“test”：“react-scripts test --env=jsdom”，“eject”：“react-scripts eject”，“heroku-postbuild”：“npm run build”}







以上这些改变对我很有效，希望对你有帮助

这可以通过两种方式解决：
1)如果您忘记设置启动脚本，通常会抛出此错误！Heroku要求将Procfile（如果您想覆盖Heroku的默认启动命令）与您的应用文件一起上传沿着。
Procfile的内容应该是这样的：
web: node index.js（即指定要为应用程序运行的node命令）
2)如果你不想上传一个Procfile，那么你可以在package.json中的"scripts"中指定你的命令（你已经做了），同时你需要在package.json中添加"build":"webpack"。
你还用"heroku-postbuild"替换了"build"脚本..

把这个添加到你的server.js中：

var distDir = __dirname + "/dist/";

app.use(express.static(distDir));

在React中，我做了两件事。一件解决了：）
1.使用https://favicon.io/favicon-converter/添加了favicon和manifest
1.从package.json中删除了未使用的软件包，您还应该向devDependencies添加开发依赖项

我已经把这段代码放在json文件中，从那时起它就完美地工作了

scripts": {
    "start": "node index.js"
}
