Installation

Follow the installation guide in the n8n community nodes documentation.

WARNING: During the npm-based installation of this plugin, puppeteer will attempt to install a working version of chrome or chromium on the machine. It's quite possible that it will either be unable to find a suitable one, or it won't work on your particular platform due to missing system dependencies. You can refer to the troubleshooting document for instructions on how to fix this.

The following steps have been known to work:

On Docker

For alpine-based images

For alpine-based images (e.g. n8nio/n8n:latest), the following command will install the latest chromium:

apk add --no-cache \
  chromium \
  nss \
  freetype \
  harfbuzz \
  ca-certificates \
  ttf-freefont

Once installed, you would then have to instruct puppeteer to use that version instead of the embedded one, by setting these env variables:

• PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true
• PUPPETEER_EXECUTABLE_PATH=/usr/bin/chromium-browser

For debian-based images

For debian-based images (e.g. n8nio/n8n:latest-debian), the following command will install the latest chrome-browser, including all dependencies, which should enable the embedded puppeteer version to also work:

apt-get update \
  && apt-get install -y wget gnupg \
  && wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - \
  && sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list' \
  && apt-get update \
  && apt-get install -y google-chrome-stable fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst fonts-freefont-ttf libxss1 --no-install-recommends \
  && rm -rf /var/lib/apt/lists/*

Cache folder

In any case, you may need to set the following env variable to instruct puppeteer where to store its embedded chrome browser binaries, since the default location may be wiped if not properly persisted in your container in a durable volume:

• PUPPETEER_CACHE_DIR=/root/.n8n/.cache/puppeteer
