puppeteerでThis relative module was not found: ~ ws ~ WebSocketTransport.js

Last updated at Posted at 2020-02-22

環境

・windows10
・vue-cli3
・electron-builder

現象

electronでpuppeteerを使おうとした。
npm run electron:serveしたら、

This dependency was not found:

* ws in ./node_modules/puppeteer/lib/WebSocketTransport.js

To install it, you can run: npm install --save ws

対応

To install it, you can run: npm install --save ws

とあるので言われたとおりにコマンドを打つ。
で、再度build。
しかし、同じエラーが…。

解決策

node_modules/puppeteer/lib/WebSocketTransport.jsをいじる。

const WebSocket = require('ws');

const WebSocket = require('../node_modules/ws');

に修正する。(wsをnpm installした後に)

備考

issueはこちら
https://github.com/puppeteer/puppeteer/issues/3487

自分の環境ではこの方法で助かったが、リンク先は割と紛糾しているみたい?
この分野(electron+αの開発)は日本語の参考記事も少ないので、じぶんみたいなぺーぺーだとわりと簡単なところで結構つまづく。
