'Buffer‘不是由__vite-浏览器-外部:缓冲区导出的

Question

我正在使用vite和sveltekit使用适配器节点获取此生成错误。

我不知道它为什么不构建，因为它依赖于节点来服务器客户端。

发展计划运作良好

'Buffer' is not exported by __vite-browser-external:buffer

我试过填充物但它们不起作用。

            optimizeDeps: {
                esbuildOptions: {
                    // Node.js global to browser globalThis
                    define: {
                        global: 'globalThis'
                    },
                    // Enable esbuild polyfill plugins
                    plugins: [
                        NodeGlobalsPolyfillPlugin({
                            process: true,
                            buffer: true,
                            webworkers: true,
                        }),
                        NodeModulesPolyfillPlugin()
                    ]
                }
            },
            build: {
                minify: true,
                rollupOptions: {
                    plugins: [
                        // Enable rollup polyfills plugin
                        // used during production bundling
                        rollupNodePolyFill()
                    ]
                }
            }

Answer 1

build: {
        rollupOptions: {
            plugins: [inject({ Buffer: ['Buffer', 'Buffer'] })],
        },
    },

这适用于npm i -D buffer

Answer 2

我通过将正确的别名(包括buffer和process)添加到config.vite.ts (这是我的样子)来解决这个问题

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import tsconfigPaths from 'vite-tsconfig-paths'
import { NodeGlobalsPolyfillPlugin } from '@esbuild-plugins/node-globals-polyfill'
import { NodeModulesPolyfillPlugin } from '@esbuild-plugins/node-modules-polyfill'
import rollupNodePolyFill from 'rollup-plugin-node-polyfills'

export default defineConfig({
    plugins: [react(), tsconfigPaths()],

    },
