Problem with WebSocketTransport.js

• Puppeteer version: v1.10.0
• Platform / OS version: Windows 7 (x64)
• Node.js version: v10.13.0

1. install a puppeteer in the project
2. try to run a project (npm run serve)
3. an error:

This dependency was not found:
* ws in ./node_modules/puppeteer/lib/WebSocketTransport.js
To install it, you can run: npm install --save ws

in fact, this dependence is established.

正常使用puppeteer是完全没有问题的，但是当我在使用vue-cli3创建的项目中使用puppeteer的时候，就会提示这个错误。我同样运行了npm install --save ws 这个命令，但是依旧不起作用。

@PeterKnight, update the node js version, I don’t remember, but it seems it helped me Hello, I had the same problem and i resolved excuted npm install --save ws and changed the path in the file WebSocketTransport.js const WebSocket = require(‘…/node_modules/ws’);
