Heroku
with Node.js
using Mac
Mac
在Heroku
上部署Node.js
My issue:我的问题:
State changed from starting to crashed &&
sh: 1: nodemon: not found &&
Failed at...start script &&
status 1...code=H10
After creating my front-end, with React
, back-end server, with node.js
/ express.js
, and database, with PostgreSQL
, I attempted to deploy my server on Heroku
with Git
.在使用
React
创建前端、后端服务器、 node.js
/ express.js
和数据库、 PostgreSQL
,我尝试使用Git
在Heroku
上部署我的服务器。 Since I already had Git
, I moved onto Heroku CLI
因为我已经有了
Git
,所以我转向了Heroku CLI
First, from the terminal
in my server...首先,从我服务器中的
terminal
...
brew install heroku/brew/heroku
heroku create
git remote -v
git push heroku master
If this is not your first time using Heroku
...如果这不是您第一次使用
Heroku
......
heroku git:remote -a theUrlYouWant
git push heroku master
...otherwise... Heroku
dynamically assigns your app a port, so you can't set the port to a fixed number. ...否则...
Heroku
动态地为您的应用分配一个端口,因此您无法将端口设置为固定数字。 Heroku adds the port to the env: Heroku 将端口添加到 env:
app.listen(process.env.PORT || 3000, () => {
console.log(`app is running on port ${process.env.PORT}`);
})
...if you added port: ...如果你添加了端口:
git add .
git commit -m "adding port"
git push heroku master
...finally, from my terminal in server: ...最后,从我在服务器中的终端:
➜ folderName git:(master) heroku open
➜ folderName git:(master) heroku logs --tail

Heroku runs in a production environment by default so it does not install the dev dependencies. Heroku 默认在生产环境中运行,因此它不会安装开发依赖项。
If you don't want to reinstall nodemon as a dependency, which I think you shouldn't, because it's right place is in devDependencies, not in dependencies...如果您不想将 nodemon 作为依赖项重新安装,我认为您不应该这样做,因为它的正确位置是在 devDependencies 中,而不是在依赖项中...
Instead, you can create a second npm script, in your package.json
, to avoid this error by running nodemon
only in your localhost:相反,您可以在
package.json
创建第二个 npm 脚本,通过仅在本地主机中运行nodemon
来避免此错误:
"scripts": {
"start": "node fileName.js",
"start:dev": "nodemon fileName.js"
},
And when you want to run the project locally, just run in your terminal npm start:dev
and it will load fileName.js
with nodemon
.当你想在本地运行项目时,只需在你的终端
npm start:dev
,它就会用nodemon
加载fileName.js
。
While in Heroku, npm start
runs by default and loads fileName.js from a normal node command and you get rid of that error.在 Heroku 中,
npm start
默认运行并从普通节点命令加载 fileName.js 并且您摆脱了该错误。

I made this post in hopes to help you avoid the time it took me to debug this issue.
我写这篇文章是为了帮助你避免我花时间调试这个问题。
Here`s what worked for me:这对我有用:
In your Heroku app, go to Settings
, then click Reveal Config Vars
and then add a new record with KEY
NPM_CONFIG_PRODUCTION
and Value
false
.在您的 Heroku 应用程序中,转到
Settings
,然后单击Reveal Config Vars
,然后使用KEY
NPM_CONFIG_PRODUCTION
和Value
false
添加新记录。
I added nodemon to the dependencies in package.json and it is working now.我将 nodemon 添加到 package.json 中的依赖项,现在它正在工作。
