我怎样才能用网络包来使用 puppet 师?无论我怎么试它都找不到。这是我所知道的:
依赖项安装在包. json中:
npm i puppeteer
In webpack.dev:
module.exports = {
// ... I'm skipping over a bunch of stuff here, then:
externals: {
puppeteer: require('puppeteer'),
}
}\\
然后在客户端的入口文件index.js中:
import puppeteer from 'puppeteer';
运行后立即:
puppeteer.launch();
只得到这个错误:
Uncaught TypeError: Cannot read property 'launch' of undefined
我做错了什么?我总是在webpack中使用外部插件。
快速更新,我尝试了webpack. providePlugin,并与jquery库并行测试,jquery遵循相同的逻辑工作,但puppeteer仍然给我一个错误:
In webpack.dev:
plugins: [
new webpack.ProvidePlugin({
puppeteer: 'puppeteer',
jQuery: 'jquery'
})
在index.js中:
import 'puppeteer'
import 'jquery'
然后我得到一堆错误,如:
/node_modules/puppeteer/lib/cjs/puppeteer/node/BrowserRunner.js
Module not found: Error: Can't resolve 'child_process' in 'C:\Users\victo\OneDrive\Desktop\20200307-kino\kino\node_modules\puppeteer\lib\cjs\puppeteer\node'

添加到您的配置如下。这在我的情况下工作。注解掉的可能也适用

我确实遇到过类似的问题,而使用webpack的节点应用程序与puppeteer作为一个依赖项。
应该能胜任。
