我遇到Heroku H20错误(应用程序启动超时),然后出现H10错误(Web进程在启动后60秒内未能绑定到$ PORT)
我的入门级瘦项目在package.json中使用sirv:
{
"name": "clicker",
"version": "0.0.1",
"scripts": {
"build": "rollup -c",
"dev": "rollup -c -w",
"start": "sirv public"
},
"engines": {
"node": "10.16.0",
"npm": "6.13.1"
},
"devDependencies": {
"rollup": "^1.12.0",
"rollup-plugin-commonjs": "^10.0.0",
"rollup-plugin-livereload": "^1.0.0",
"rollup-plugin-node-resolve": "^5.2.0",
"rollup-plugin-svelte": "^5.0.3",
"rollup-plugin-terser": "^5.1.2",
"svelte": "^3.0.0"
},
"dependencies": {
"sirv-cli": "^0.4.4"
}
}
我似乎无法弄清楚如何通过$ PORT环境变量Heroku给您传递。我已经尝试过
"start": "sirv public --port $PORT"
The closest solution我发现这是指Heroku动态为您的应用分配端口的事实,但是我发现的所有解决方案都涉及在node中使用process.env.port,但我似乎无法弄清楚在我的package.json文件中说明如何与sirv结合使用。它基本上不是在命令行上运行“ sirv public”吗?因此,我不能仅在其中使用process.env.port,因为那是用于访问代码中的port变量...

有什么想法吗?
答案 0 :(得分:1)
使用内容创建一个.env
文件(添加到.gitignore
)
HOST=localhost
PORT=5000
package.json
启动命令:
{
"start": "sirv public --host $HOST --port $PORT"
}
在本地运行以进行开发时执行:
heroku local
这将从.env
提取您的环境变量
在生产中,Heroku将提供$HOST
和$PORT
$HOST
可能可以用硬编码的0.0.0.0
代替:

By default, the server will only respond to requests from localhost. To allow connections from other computers, edit the sirv commands in package.json to include the option --host 0.0.0.0.
我将此添加到我的package.json中,它已成功完全安装在heroku上!
