以下是代码： String path = "/Users/yezhi/IdeaProjects/demo02/.local-browser/mac-722234/chrome-mac/Chromium.app/Contents/MacOS/Chromium"; ArrayList arrayList = new ArrayList<>(); //生成pdf必须在无厘头模式下才能生效 LaunchOptions options = new LaunchOptionsBuilder() .withArgs(arrayList) .withHeadless(true) .withExecutablePath(path) .build(); arrayList.add("--no-sandbox"); arrayList.add("--disable-setuid-sandbox"); Browser browser = Puppeteer.launch(options); Page page = browser.newPage(); page.goTo("https://www.baidu.com/?tn=98012088_10_dg&ch=3"); PDFOptions pdfOptions = new PDFOptions(); pdfOptions.setPath("test.pdf"); page.pdf(pdfOptions); page.close(); browser.close();

Mac请使用本机的Chrome运行，参考路径：/Applications/Google\ Chrome.app/Contents/MacOS/Google Chrome

好的，使用本机chrom已经能执行成功了。 而且参考地址刚好就是本机chrome地址。感谢。
