puppeteer 安裝失敗的解決辦法

安裝錯誤

安裝puppeteer時由於須要下載chrom的緣故老是安裝失敗提示:

ERROR: Failed to download Chromium r515411! Set "PUPPETEER_SKIP_CHROMIUM_DOWNLOA D" env variable to skip download.
{ Error: read ECONNRESET
    at _errnoException (util.js:1024:11)

yscall: 'read' }
npm WARN day2@1.0.0 No repository field.
複製代碼

提示須要跳過安裝Chromiumset PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=1

解決辦法

執行npm install puppeteer --ignore-scripts 跳過安裝chromuin步驟

而後在腳本中經過配置項 executablePath，指定 Chromium 所在的位置。示例：

const puppeteer = require('puppeteer');


(async () => {
    const browser = await puppeteer.launch({
        executablePath: '../../chromium/Chromium.app/Contents/MacOS/Chromium'
    });
    const page = await browser.newPage();
    await page.goto('https://y.qq.com');
    await page.screenshot({path: 'yqq.png'});
    browser.close();
})();

手動下載Chromuim

牆裏下載不到Chromuim怎麼辦。看倉庫源碼能夠發現下載地址是這樣的

const downloadURLs = {
    linux: 'https://storage.googleapis.com/chromium-browser-snapshots/Linux_x64/%d/chrome-linux.zip',
    mac: 'https://storage.googleapis.com/chromium-browser-snapshots/Mac/%d/chrome-mac.zip',
    win32: 'https://storage.googleapis.com/chromium-browser-snapshots/Win/%d/chrome-win32.zip',
    win64: 'https://storage.googleapis.com/chromium-browser-snapshots/Win_x64/%d/chrome-win32.zip'
}
複製代碼

選擇對應的平臺，將 %d 替換成具體的編號,編號能夠從 puppeteer/package.json 中的 puppeteer.chromium_revision查看

而後運行咱們的代碼就一切正常了。

哎！ ，國外大公司新出的框架，庫，工具咱們咱們大天朝內使用太難了，老是各類採坑，今天在家搞了半天才把puppeteer運行正常
