Question

我试图以headless：false模式启动人偶。它在我的本地计算机上正常工作，但是当我将其推送到服务器并尝试启动它时，出现此错误：

当我以headless：true模式启动时，我没有得到htis错误。任何想法如何解决这个问题？这就是我启动人偶的方式：

var browser = await puppeteer.launch({
   args: [
   '--ignore-certificate-errors',
   '--no-sandbox',
   '--disable-setuid-sandbox',
   '--window-size=1920,1080',
   "--disable-accelerated-2d-canvas",
   "--disable-gpu"],
   ignoreHTTPSErrors: true,
   headless: false,
 });

Answer 1

您可以尝试欺骗无头chrome以在启用GPU的情况下运行：

const browser = await puppeteer.launch({
   headless: false,
   args: ['--headless'],
 })

Answer 2

1。您必须安装一些lib软件包。

gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 \
libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 \
libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 \
libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 \
ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget \
xvfb x11vnc x11-xkb-utils xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic x11-apps

2。然后使用您的脚本启动xvfb

示例：

xvfb-run --server-args="-screen 0 1024x768x24" npm start

如果您使用Docker，请遵循此docker文件

FROM node:8
RUN apt-get update && \
apt-get install -yq gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 \
libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 \
libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 \
libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 \
ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget \
xvfb x11vnc x11-xkb-utils xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic x11-apps
WORKDIR /app
COPY package.json /app
RUN npm install
COPY . /app
EXPOSE 8081
CMD xvfb-run --server-args="-screen 0 1024x768x24" npm start

以下是带有xvfb的木偶戏的示例 https://github.com/nsourov/Puppeteer-with-xvfb

Answer 3

对我来说有效：

const puppeteer = require('puppeteer');

(async () => {
        const browser = await puppeteer.launch({ headless: false });

        console.log(await browser.userAgent());

        await browser.close();
})();

Answer 4

以下内容对我有用

const puppeteer = require("puppeteer");
async function getData() {
   const browser = await puppeteer.launch({ headless: false });
}
getData();

人偶没有在无头：假模式下运行
