问题描述
我有一个微服务,其中一个API正在生成PDF(基于作为参数传递的类型的3个pdf)。我已经使用了puppeteer软件包来生成PDF。可以在我的本地系统上使用。
当我尝试在EC2 ubuntu 16.04服务器上运行相同的微服务时,无法启动无头铬。我使用过“ npm i puppeteer”,据我了解,它应该使铬无头依赖。
微服务运行正常,但问题出在操纵p的铬中。
Error: Could not find browser revision 800071. Run "PUPPETEER_PRODUCT=firefox npm install" or "PUPPETEER_PRODUCT=firefox yarn install" to download a supported Firefox browser binary.
此外,我在“ / node_modules / puppeteer /” 中找不到“。local-chromium / linux- {version} / linux-chrom” >
所以,我的理解是chrome从未安装
我对docker也很满意。我仅在docker中运行其他微服务。因此,如果有人可以建议使用docker的一些解决方法,那也可以。
微服务的相关代码部分
async function createPDF(baseFile,inp) {
var templateHtml = fs.readFileSync(
path.join(process.cwd(),`utilities/${baseFile}.html`),"utf8"
);
var template = handlebars.compile(templateHtml);
var html = template(inp);
var milis = new Date();
milis = milis.getTime();
var pdfPath = path.join(process.cwd(),`${baseFile}.pdf`);
var options = {
width: "1100px",height: "1380px",// format: "A3",headerTemplate: "<p></p>",footerTemplate: "<p></p>",displayheaderfooter: false,margin: {
top: "10px",bottom: "10px",},// printBackground: true,};
const browser = await puppeteer.launch({
args: ["--no-sandBox","--disable-setuid-sandBox"],headless: true,});
var page = await browser.newPage();
await page.goto(`data:text/html;charset=UTF-8,${html}`,{
waitUntil: "networkidle0",});
// await page.addStyleTag({
// content:
// "@page:first {margin-top:10px; margin-right:10px; margin-bottom:30px; margin-left:10px;}",// });
const pdf = await page.pdf(options);
await browser.close();
return pdf;
}
npm i puppeteer
的输出 npm i puppeteer

解决方法
Puppeteer Error: Chromium revision is not downloaded-此链接帮助我调试了需要在puppeteer中手动运行install.js的情况。

此外,apt-get install libgbm-dev
