我尝试在实时 ubuntu 18 服务器上的 laravel 5.8 应用程序中安装 spatie/browsershot，并且我需要这样做 安装 Chrome 支持我尝试运行命令：
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt-get install -y nodejs gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgbm1 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 libgbm-dev
sudo npm install --global --unsafe-perm puppeteer
sudo chmod -R o+rx /usr/lib/node_modules/puppeteer/.local-chromium
但是我在运行第一个命令时出错：
servername@staging-servername:~/www/laravel.servername.io$ who
servername pts/0 Mar 20 14:18 (NNN.NNN.NNN.NNN)
servername@staging-servername:~/www/laravel.servername.io$ lsb_release -d; uname -r; uname -i

[sudo] password for servername:
