[vite:load-fallback] Could not load ~/src/@emotion/react/jsx-runtime (imported by src/index.tsx): ENOENT: no such file or directory, open '~/src/@emotion/react/jsx-runtime'
error during build:
Error: Could not load ~/src/@emotion/react/jsx-runtime (imported by src/index.tsx): ENOENT: no such file or directory, open '~/src/@emotion/react/jsx-runtime'

hello, I have a problem....
This error occurs when built using vite.

here is my vite.config.js / tsconfig.json / dependencies

import { resolve } from 'path';
import react from 'plugin-react-swc-emotion';
// import react from '@vitejs/plugin-react-swc';
import { defineConfig } from 'vite';
import tsconfigPaths from 'vite-tsconfig-paths';
import vitePluginDts from 'vite-plugin-dts';
import { nodeResolve } from '@rollup/plugin-node-resolve';

// https://vitejs.dev/config/
export default defineConfig({
    plugins: [
        react(),
       // 
       // react({
       //     jsxImportSsource: "@emotion/react"
       // }),
        tsconfigPaths({
            root: './',
            projects: ['./tsconfig.json'],
        }),
        vitePluginDts({
            insertTypesEntry: true,
        }),
    ],
    build: {
        lib: {
            entry: resolve(__dirname, 'src/index.tsx'),
            name: 'my-lib,
            fileName: 'index',
        },
        rollupOptions: {
            external: [

                "typescript",
            ],
            plugins: [nodeResolve({
                resolveOnly : [...]
            })]

        },
    },
});

}

I used 'plugin-react-swc-emotion' after seeing this issue #25, but the results did not change...

[ArnaudBarre]

This partial repro is using comments for the plugin. Could you provide a more complete reproduction that shows an issue with this plugin only (and not plugin-react-swc-emotion)?

[jjunyjjuny]

Thank you for your reply.
Is this good enough?

.ts is built, but .tsx is not built

[ArnaudBarre]

I can't repro there is still too much missing pieces. Can you provide a very small repo to reproduce? See https://antfu.me/posts/why-reproductions-are-required

My guess for now is a bad interaction between vite-tsconfig-paths and this plugin.

[jjunyjjuny]

I'll give it a try. I'll be right back!

[jjunyjjuny]

Hi. I've solved this problem.

As you said, the conflict between 'vite-tsconfig-paths' and other plug-ins ("@rollup/plugin-node-resolve") was the problem!

Your plug-in is not at fault.

Thank you for your reply, and thank you again for making a good plug-in.

Happy New Year!

[ArnaudBarre]

Cool that you solved it 🎉
