我的项目是一个桌面Electron应用程序,单击该应用程序会刮擦一个网站。很简单。
我的项目在本地运行正常(当然),但是当我运行npm run package-win
并创建Windows生产应用程序时,我相信当puppeteer尝试启动浏览器时会出现错误。
我仅在针对Windows构建时得到此信息。可以在我的Mac上构建,并且没有错误...
Chromium revision is not downloaded. Run "npm install" or "yarn install" at Launcher.launch
我尝试删除package.lock,node_modules文件夹,并且当然按照建议运行npm install
。我认为这与版本控制有关吗?这是我的package.json
文件:
{
"name": "my-project",
"version": "1.0.0",
"description": "My project description.",
"main": "main.js",
"scripts": {
"start": "electron .",
"package-win": "electron-packager . my-project --overwrite --asar=true --platform=win32 --arch=ia32 --icon=assets/icons/win/icon.ico --prune=true --out=release-builds --version-string.CompanyName=CE --version-string.FileDescription=CE --version-string.ProductName=\"My Project\""
},
"license": "CC0-1.0",
"devDependencies": {
"electron": "^2.0.12",
"electron-packager": "^12.2.0"
},
"dependencies": {
"electron-json-storage": "^4.1.4",
"nodemailer": "^4.6.7",
"puppeteer": "^1.8.0"
}
}
我可以说我的try catch失败了,因为错误消息来自catch,所以此块中的某些内容失败了,但仅限于生产版本:
async scrape(url) {
try {
// Launch & Setup browser
this.browser = await puppeteer.launch({
args: ["--no-sandbox"],
headless: true
});
this.page = await this.browser.newPage();
await this.page.setViewport({
width: 1920,
height: 926
});
this.page.setUserAgent('Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36');
await this.page.goto(url);
await this.page.waitForSelector('ul.rows');
// Get all the listings on the page
this.listings_array = await this.get_DOM_elements_from_page();
console.log(this.listings_array);
} catch (err) {
console.log('SOMETHING WENT WRONG', err);
}
}
此函数在类内部。这就是为什么引用this
的原因。我将浏览器,页面和其他内容存储在刮板实例上。

"pkg": "rm -rf ./pkg && pkg -t node8-macos-x64 --out-path pkg .",
"postpkg": "mkdir -p ./pkg/node_modules/puppeteer && cp -R ./node_modules/puppeteer/.local-chromium ./pkg/node_modules/puppeteer"
将此添加到您的package.json
