const path = __dirname; await page.screenshot({ path }); 这样写会报错 (node:22882) UnhandledPromiseRejectionWarning: Error: Unsupported screenshot mime type: null at assert (/Users/mac/Documents/mydemo/Puppeteer_12/node_modules/puppeteer/lib/helper.js:279:11) at Page.screenshot (/Users/mac/Documents/mydemo/Puppeteer_12/node_modules/puppeteer/lib/Page.js:869:7) at Page.
