Heroku部署失败：SH：1：NG：未找到 [英] Failed Heroku deploy: sh: 1: ng: not found

问题描述

Heroku部署失败。我一直在寻找其他类似的堆栈溢出帖子，并更改Package.json文件，尝试对其他人有效但运气不佳的解决方案。我不确定这是端口问题，还是Package.json问题，还是完全不同的问题。我们非常感谢您的任何帮助、提示或建议！

})

推荐答案

您是否检查了此处的调试日志/app/.npm/_logs/2019-02-09T08_33_03_316Z-debug.log？

我建议先查看调试日志，以获取解决问题的更多详细信息。

更新

Its an H10 error. "heroku[router]: at=error code=H10 desc="App crashed"
method=GET path="/favicon.ico" host=angular-lottery-genie.herokuapp.com
request_id=30e63a79-c395-4d2a-9987-938bcc350629 fwd="50.250.113.70" dyno=
connect= service= status=503 bytes= protocol=https"

您的应用程序崩溃。以下是您可以做的一些事情：

1.)重新启动Heroku。您应该安装了Heroku CLI。以下是链接：Heroku CLI Install。并在您的终端上运行heroku restart。

2.)使用Heroku动态设置的端口，通常可以在process.env.PORT访问，并将您想要的端口设置为备份：

app.listen(process.env.PORT || 3000, function(){
  console.log("Node app is running at localhost:" + app.get('port'));
});

3.)尝试通过在终端中键入以下内容来检查您的node和npm版本：

node --version
npm --version

并更新您的Package.json文件下指示的node和npm版本：

"engines": {
  "node": "10.15.1",
  "npm": "6.4.1"
}

您的问题的另一个更新：

npm ERR! enoent ENOENT: no such file or directory

这些错误通常与程序包损坏或不兼容有关。您可以做的：

1.)请确保没有其他节点实例在后台运行，然后重试NPM命令。

2.)删除node_modules目录和package-lock.json(如果有)。在项目目录内的终端中重新安装运行npm install(或用于安装这些包的任何命令)的包。

3.)将节点升级到最新版本，删除node_modules目录和package-lock.json，然后重新安装程序包。

4.)如果npm仍然不适合您，请尝试yarn包管理器(Yarn)。

5.)如果程序包安装仍然失败，请检查错误日志文件以获取错误的详细报告。
