问题描述
我正尝试在无头：错误模式下启动木偶操纵者。它在我的本地计算机上工作，但当我将其推送到服务器并尝试启动它时，我收到以下错误：
4|scraperP | You have triggered an unhandledRejection, you may have forgotten to catch a Promise rejection:

当我在Headless：True模式下启动时，我没有收到错误消息。你知道怎么解决这个问题吗？这就是我如何启动木偶操纵者：
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,
});
推荐答案
1.您必须安装一些lib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
