vite引入web3及其他相关库等问题
2021-11-17
vite 使用web3，@walletconnect/web3-provider 或者其他库，出了一系列vite的相关问题
// example
Uncaught ReferenceError: process is not defined
Uncaught ReferenceError: global is not defined
Uncaught ReferenceError: Buffer is not defined
...........
最终解决方案
在 index.html添加
<script>window.global = window;</script>
<script type="module">
import process from "process";
import { Buffer } from "buffer";
import EventEmitter from "events";
window.Buffer = Buffer;
window.process = process;
window.EventEmitter = EventEmitter;
</script>
在vite.config.ts
import vue from '@vitejs/plugin-vue'
export default {
resolve: {
alias: {
process: "process/browser",
stream: "stream-browserify",
zlib: "browserify-zlib",
util: 'util'
}
},
plugins: [
vue(),
]
}
添加这些依赖项 browserify-zlib, events, process, stream-browserify,util
最终完美解决
最新更新
build打包完，还是发现walletconnect的包有点问题。require,buffer之类的问题。
苦寻良久，解决方案
在vite.config.ts中添加如下配置
//vite.config.ts
import inject from '@rollup/plugin-inject'
build: {
rollupOptions: {
// @ts-ignore
plugins: [inject({ Buffer: ['buffer', 'Buffer'] })],
},
commonjsOptions: {
transformMixedEsModules: true,
},
},

另一个简单解决方案
import { nodePolyfills } from 'vite-plugin-node-polyfills'vite.config.js
这里更新新的node兼容方案
import { NodeGlobalsPolyfillPlugin } from '@esbuild-plugins/node-globals-polyfill' import { NodeModulesPolyfillPlugin } from '@esbuild-plugins/node-modules-polyfill' import rollupNodePolyFill from 'rollup-plugin-node-polyfills'vite.config.js
resolve: { alias: { '@': resolve(__dirname, 'src'), util: 'rollup-plugin-node-polyfills/polyfills/util', events: 'rollup-plugin-node-polyfills/polyfills/events', stream: 'rollup-plugin-node-polyfills/polyfills/stream', path: 'rollup-plugin-node-polyfills/polyfills/path', punycode: 'rollup-plugin-node-polyfills/polyfills/punycode', os: 'rollup-plugin-node-polyfills/polyfills/os', assert: 'rollup-plugin-node-polyfills/polyfills/assert', constants: 'rollup-plugin-node-polyfills/polyfills/constants', _stream_duplex: 'rollup-plugin-node-polyfills/polyfills/readable-stream/duplex', _stream_passthrough: 'rollup-plugin-node-polyfills/polyfills/readable-stream/passthrough', _stream_readable: 'rollup-plugin-node-polyfills/polyfills/readable-stream/readable', _stream_writable: 'rollup-plugin-node-polyfills/polyfills/readable-stream/writable', _stream_transform: 'rollup-plugin-node-polyfills/polyfills/readable-stream/transform', timers: 'rollup-plugin-node-polyfills/polyfills/timers', vm: 'rollup-plugin-node-polyfills/polyfills/vm', zlib: 'rollup-plugin-node-polyfills/polyfills/zlib', tty: 'rollup-plugin-node-polyfills/polyfills/tty', domain: 'rollup-plugin-node-polyfills/polyfills/domain', buffer: 'rollup-plugin-node-polyfills/polyfills/buffer-es6', process: 'rollup-plugin-node-polyfills/polyfills/process-es6' } }, optimizeDeps: { esbuildOptions: { // Node.js global to browser globalThis define: { global: 'globalThis' }, // Enable esbuild polyfill plugins plugins: [ NodeGlobalsPolyfillPlugin({ process: true, buffer: true }), NodeModulesPolyfillPlugin() ] } }, build: { rollupOptions: { plugins: [ rollupNodePolyFill(), ], output: { } } }我也是线上环境使用web3的功能 就报错：TypeError: Cannot read properties of undefined (reading 'call')
请教大佬可有解决？ 是什么原因？
跪谢！
大佬，我配置了之后还是不可用，给你发邮件了

已邮件回复你了
江湖救急...你的prod模式没有任何问题吗，web3功能正常使用吗？我本地是没有问题的，一打包后使用功能就报错TypeError: Cannot read properties of undefined (reading 'call')。
兄弟你好，我按照你的方式去做了，但是打包后，线上环境使用web3的功能 就报错：TypeError: Cannot read properties of undefined (reading 'call')。这是什么问题呢，困扰我很久了...
希望你能帮帮我，我愿意有偿求助，方便留个联系方式吗，重谢！
