但我遇到一些错误：
/var/www/my_proj/idf/static/js # node render.js uid=uid-param url=https://www.targethost.example token=tk-param out=/tmp/test.pdf
(node:167) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Failed to launch chrome!

似乎无法实例化铬。我还尝试在它创建浏览器实例的同时修改render.js脚本：
const browser = await puppeteer.launch({
args: ['--no-sandbox'],
headless: false
});
但我得到了相同的结果。有什么帮助吗？
这对我有用
使用Puppeteer v0.13.0。撰写本文时，Puppeteer的最新版本与Alpine linux中的铬不兼容。
PUPPETEER_SKIP_CHROMIUM_DOWNLOAD="true" 安装Puppeteer时将跳过下载默认版本的Chromium。
Dockerfile：
FROM node:11-alpine
ENV CHROME_BIN="/usr/bin/chromium-browser"\
PUPPETEER_SKIP_CHROMIUM_DOWNLOAD="true"
RUN set -x \
&& apk update \
&& apk upgrade \
# replacing default repositories with edge ones
&& echo "http://dl-cdn.alpinelinux.org/alpine/edge/testing" > /etc/apk/repositories \
&& echo "http://dl-cdn.alpinelinux.org/alpine/edge/community" >> /etc/apk/repositories \
&& echo "http://dl-cdn.alpinelinux.org/alpine/edge/main" >> /etc/apk/repositories \
\
# Add the packages
&& apk add --no-cache dumb-init curl make gcc g++ python linux-headers binutils-gold gnupg libstdc++ nss chromium \
\
&& npm install [email protected] \
\
# Do some cleanup
&& apk del --no-cache make gcc g++ python binutils-gold gnupg libstdc++ \
&& rm -rf /usr/include \
&& rm -rf /var/cache/apk/* /root/.node-gyp /usr/share/man /tmp/* \
&& echo
ENTRYPOINT ["/usr/bin/dumb-init"]
CMD node
NodeJ：
您需要通过以下配置告诉Puppeteer使用已安装的Chromium版本- executablePath: '/usr/bin/chromium-browser'
const puppeteer = require('puppeteer');
puppeteer
.launch({
executablePath: '/usr/bin/chromium-browser',
args: ['--no-sandbox', '--disable-dev-shm-usage'],
})
.then(async (browser) => {
// your code
});
