AppEngine 标准版不支持 Node.js。所以你可能在 Flex 环境中运行。
我从这个 [1] 开始。请参阅 package.json 差异。
我修改了 package.json 以匹配您的情况，并在 app.js 中尝试了噩梦。
我可以通过替换来重现您的情况
"start": "xvfb-run -a node app.js",
在 package.json 上：
xvfb-run -a DEBUG=nightmare node app.js
上一条命令的帮助页面显示：
-a --auto-servernum try to get a free server number, starting at
--server-num
-e FILE --error-file=FILE file used to store xauth errors and Xvfb
output (default: /dev/null)
-f FILE --auth-file=FILE file used to store auth cookie
(default: ./.Xauthority)
-h --help display this usage message and exit
-n NUM --server-num=NUM server number to use (default: 99)
-l --listen-tcp enable TCP port listening in the X server
-p PROTO --xauth-protocol=PROTO X authority protocol name to use
(default: xauth command's default)
-s ARGS --server-args=ARGS arguments (other than server number and
"-nolisten tcp") to pass to the Xvfb server
(default: "-screen 0 640x480x8")
我看不到任何关于 DEBUG 的信息...
所以你可能想做这样的事情：
xvfb-run -e error.log -a node app.js
保存错误，但我不确定。
我将分享我的配置。
我在运行“sudo npm install”之前和之后与您分享：
我补充说：
"preinstall": "apt-get update && apt-get install -y libfontconfig1 libgtk2.0-0 libgconf-2-4 libasound2 libxtst6 libxss1 libnss3 xvfb && npm install nightmare",
并修改：
“开始”：“节点 app.js”，
到：
"start": "xvfb-run -a node app.js",
before:
{
"name": "appengine-hello-world",
"description": "Simple Hello World Node.js sample for Google App Engine Flexible Environment.",
"version": "0.0.1",
"private": true,

"deploy": "gcloud app deploy",
"start": "xvfb-run -a node app.js",
"lint": "samples lint",
"pretest": "npm run lint",

},
"cloud-repo-tools": {
"test": {
"app": {
"msg": "Hello, world!"
}
},
"requiresKeyFile": true,
"requiresProjectId": true
}
}
在“npm install”之后，文件自动更新到：
{

"description": "Simple Hello World Node.js sample for Google App Engine Flexible Environment.",
"version": "0.0.1",
"private": true,

"lint": "samples lint",
"pretest": "npm run lint",
"system-test": "samples test app",

},
"dependencies": {

"nightmare": "^2.10.0"
},
"devDependencies": {

},
"cloud-repo-tools": {

}
},
"requiresKeyFile": true,
"requiresProjectId": true
}
}
我正在与噩梦分享一个sn-p js：
'use strict';
// [START app]
const express = require('express');
const app = express();
const Nightmare = require('nightmare')
app.get('/', (req, res) => {
Nightmare({show: false})
.goto('https://google.com')
.wait('body')
.insert('input[aria-label="Search"]', 'node-nightmare github.com')
.click('input[type="submit"]')
.wait(1000)
.wait('body')
.evaluate(function() {
// return $('a:contains("node-nightmare")').text();
// res.status(200).send($('a:contains("node-
nightmare")').text()).end();
console.log('EVALUATE');
})
.then(function(ret) {
console.log('THEN');
console.log(ret)
});
res.status(200).send('Hello, world!!!!!').end();
});
// Start the server
const PORT = process.env.PORT || 8080;
app.listen(PORT, () => {
console.log(`App listening on port ${PORT}`);
console.log('Press Ctrl+C to quit.');
});
// [END app]
您可以在本地服务器上运行：
npm 开始
或部署到 App Engine
gcloud 应用部署
希望对你有帮助！
