Fails on running in a symbolic linked directory

[AlttiRi]

Describe the bug

Vite fails when I try to use it in a sym-linked directory.

Run in CMD:

npm create vite@latest my-vue-app -- --template vue
cd my-vue-app
npm install
cd ..

mklink /d linked-dir my-vue-app
cd linked-dir
npm run dev

Error:

Real life use case: moving C:/projects (a folder with your projects) to another place, for example, to D:/projects and creating a symbolic link in the old location that leads to the new location in order to keep all software (that relies on this path (like IDE)) working as earlier.
I expect that it will work totally transparently.

It's likely on this line that we didn't take into account of this specific case.

	return outputs[
	normalizePath(
	path.relative(process.cwd(), path.join(cacheDirOutputPath, flatId))
	)
	]

Or the other possibility is that esbuild doesn't correctly return the output after bundling. Would you help check how this path look like on your machine? If it's incorrectly indexing the output, would also appreciate if you can submit a PR for it.

[AlttiRi]

function esbuildOutputFromId(outputs, id, cacheDirOutputPath) {
    const flatId = flattenId(id) + '.js';
    
    // ---
    const wd = process.cwd();
    const rel = path$n.relative(process.cwd(), path$n.join(cacheDirOutputPath, flatId));
    const norm = normalizePath$3(rel);
    
    console.log(wd);    // C:\projects\linked-dir
    console.log(rel);   // node_modules\.vite\deps_temp\vue.js
    console.log(norm);  // node_modules/.vite/deps_temp/vue.js
    console.log(Object.keys(outputs));

    return outputs[normalizePath$3(path$n.relative(process.cwd(), path$n.join(cacheDirOutputPath, flatId)))];
}

I had the same issue and I searched for 30 min ton understand what was going on...

[CEbbinghaus]

@patak-dev You reopened this Issue? I am currently still experiencing this with v3.2.5 which I would assume would contain the fix since it was released 2 weeks ago. What's the status on this?

[sapphi-red]

I guess this is related with nodejs/node#34866, similar to #10802.

I search many sites, finally I know why my program failed to work!
Thank you!

Still relevant found to be repeatable in vite as of node versions LTS (v20.11.1) and latest (v21.6.2) and vite (^5.0.11).

mklink /d linked-dir my-vue-app treats my-vue-app as your source folder and linked-dir as a symbolic link. That's why cd linked-dir > npm run dev won't work.
Move the source folder to your linked-dir (the place you want to run vite) and create a symbolic link to your old my-vue-app folder. Then cd linked-dir > npm run dev will work!

I would like to provide some of my findings to help resolve this issue:

1. Since my project uses pnpm, there are a lot of symlinked dependencies.
2. This issue is intermittent but occurs very frequently, and it often stems from react dependency. It's in peerDeps.
3. I'm using a workspace, and the issue seems to arise because the packages/user directory is missing between the projectRoot and user directories during output parsing.

for (const [key, value] of Object.entries(outputs)) {
  if (key.includes('react.js') && id == 'react') {
      console.log('cwd: ', cwd) // /Users/linhuangdong/Git/projectRoot
      console.log('key: ', key) // ../user/node_modules/.vite/deps_temp_ee3bd11b/react.js
      console.log('normalizedOutputPath: ', normalizedOutputPath) // packages/user/node_modules/.vite/deps_temp_ee3bd11b/react.js
  }
  if (normalizePath$3(path$n.relative(cwd, key)) === normalizedOutputPath) {
    return value;
  }
}
