我有一个在 Laradock 上运行的 Laravel 项目，我正在尝试使用这个包从视图中生成 PDF 文件：https ://github.com/spatie/browsershot

它使用 Puppeteer 来完成该部分并使用无头镀铬。

至此，我刚刚制作了一个控制器，它调用了一个基本函数进行测试：

 $image = Browsershot::url('https://example.com')
        ->noSandbox()
        ->screenshot();

我得到错误：

Error: Failed to launch the browser process! /var/www/projects/my-project/node_modules/puppeteer/.local-chromium/linux-856583/chrome-linux/chrome: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory TROUBLESHOOTING: https://github.com/puppeteer/puppeteer/blob/main/docs/troubleshooting.md

我确实通过 npm 在本地安装了 puppeteer 并且/var/www/projects/my-project/node_modules/puppeteer/.local-chromium/linux-856583/chrome-linux/chrome确实存在。

我不确定该怎么做。在 Browsershot 文档中，它说您可以运行：

curl -sL https://deb.nodesource.com/setup_12.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

在锻造。我不确定这是否也适用于我的 laradock 环境。但是错误是抱怨它在我的文件夹中找不到该文件node_modules。

完整的原始错误是：

The command "PATH=$PATH:/usr/local/bin NODE_PATH=`npm root -g` node '/var/www/projects/my-project/vendor/spatie/browsershot/src/../bin/browser.js' '{"url":"https:\/\/example.com","action":"screenshot","options":{"type":"png","args":["--no-sandbox"],"viewport":{"width":800,"height":600}}}'" failed.

编辑：在我的 Dockerfile 中添加了以下内容php-fpm

RUN 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-unstable fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst fonts-freefont-ttf \
      --no-install-recommends \
    && rm -rf /var/lib/apt/lists/*


RUN curl -sL https://deb.nodesource.com/setup_12.x | bash - \
    && apt-get install -y nodejs \
    && npm install --global --unsafe-perm puppeteer \
    && chmod -R o+rx /usr/lib/node_modules/puppeteer/.local-chromium

该/usr/lib/node_modules/文件夹从未创建，现在当我尝试加载页面时，出现503错误。
