After downgrade and upgrade puppeteer a few times,I got an error of Chromium revision is not downloaded.

My solution is

1. download app from https://storage.googleapis.com/chromium-browser-snapshots/Mac/526987/chrome-mac.zip 526987 is the chrome version your puppeteer need .Other OS https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html
2. move the app file into {home}/node_modules/puppeteer/.local-chromium/mac-526987/chrome-mac

rules:

const downloadURLs = {
  linux: '%s/chromium-browser-snapshots/Linux_x64/%d/chrome-linux.zip',
  mac: '%s/chromium-browser-snapshots/Mac/%d/chrome-mac.zip',
  win32: '%s/chromium-browser-snapshots/Win/%d/chrome-win32.zip',
  win64: '%s/chromium-browser-snapshots/Win_x64/%d/chrome-win32.zip',
};
revisionInfo(revision) {
    const folderPath = this._getFolderPath(revision);
    let executablePath = '';
    if (this._platform === 'mac')
      executablePath = path.join(folderPath, 'chrome-mac', 'Chromium.app', 'Contents', 'MacOS', 'Chromium');
    else if (this._platform === 'linux')
      executablePath = path.join(folderPath, 'chrome-linux', 'chrome');
    else if (this._platform === 'win32' || this._platform === 'win64')
      executablePath = path.join(folderPath, 'chrome-win32', 'chrome.exe');
    else
      throw 'Unsupported platform: ' + this._platform;
    let url = downloadURLs[this._platform];
    url = util.format(url, this._downloadHost, revision);
    const local = fs.existsSync(folderPath);
    return {revision, executablePath, folderPath, local, url};
  }
