我在heroku上部署了一个应用程序,并添加了伪造的Heroku buildpack。
成功重新部署后,我尝试运行它,但失败。使用heroku logs -t
,我收到此错误消息:
2018-09-07T13:16:10.870497+00:00 app[web.1]: Error: Failed to launch chrome!
2018-09-07T13:16:10.870512+00:00 app[web.1]: [0907/131610.045486:FATAL:zygote_ho

md for more information on developing with the SUID sandbox. If you want to live
dangerously and need an immediate workaround, you can try using --no-sandbox.

您应该能够通过将--no-sandbox
和--disable-setuid-sandbox
标志传递到puppeteer.launch()
来解决此问题:
const browser = await puppeteer.launch({
'args' : [
'--no-sandbox',
'--disable-setuid-sandbox'
]
});
如果这不起作用,您可能需要阅读Puppeteer官方故障排除指南:Running Puppeteer on Heroku。

这对我有用。首先,我清除所有构建包,然后添加puppeteer-heroku-buildpack和heroku / nodejs一个:
$ heroku buildpacks:clear
$ heroku buildpacks:add --index 1 https://github.com/jontewks/puppeteer-heroku-buildpack
$ heroku buildpacks:add --index 1 heroku/nodejs
然后,将以下args添加到操纵up的启动函数中:
const browser = await puppeteer.launch({
'args' : [
'--no-sandbox',
'--disable-setuid-sandbox'
]
});
最后,将其部署回Heroku:
$ git add .
$ git commit -m "Fixing deployment issue"
$ git push heroku master

This answer 很棒,但为了一个最小的、可运行的示例,我想我会分享我的完整代码和工作流程,用于启动和运行基于 Puppeteer 的网络应用程序。
请参阅 this answer 以获取简单的调度程序和时钟进程版本(尽管所有三种方法都可以在一个应用中共存,而无需执行任何特殊操作)。
package.json

"name": "test-puppeteer",
"version": "1.0.0",
"description": "",
"scripts": {
"start": "node index.js"
},
"author": "",
"license": "ISC",
"dependencies": {
"express": "^4.17.1",
"puppeteer": "^9.1.1"

}
Procfile

index.js
:const express = require("express");
const puppeteer = require("puppeteer");
const app = express();
app.set("port", process.env.PORT || 5000);
const browserP = puppeteer.launch({
args: ["--no-sandbox", "--disable-setuid-sandbox"]
});
app.get("/", (req, res) => {
// FIXME move to a worker task; see https://devcenter.heroku.com/articles/node-redis-workers
let page;
(async () => {
page = await (await browserP).newPage();
await page.setContent(`<p>web running at ${Date()}</p>`);
res.send(await page.content());
})()
.catch(err => res.sendStatus(500))
.finally(async () => await page.close())
;
});
app.listen(app.get("port"), () =>
console.log("app running on port", app.get("port"))
);
安装 Heroku CLI 并使用 Node 和 Puppeteer 构建包创建一个新应用程序(请参阅 this answer):
heroku create
heroku buildpacks:add --index 1 https://github.com/jontewks/puppeteer-heroku-buildpack -a cryptic-dawn-48835
heroku buildpacks:add --index 1 heroku/nodejs -a cryptic-dawn-48835
(将 cryptic-dawn-48835
替换为您的应用名称)
部署:
git init
git add .
git commit -m "initial commit"
heroku git:remote -a cryptic-dawn-48835
git push heroku master
验证它是否适用于 curl https://cryptic-dawn-48835.herokuapp.com
