Parcel Serve 2.8.0 randomly crashes while rebuilding

[roddypratt]

After editing an HTML file and resaving, parcel will occasionally bomb out with the following trace.

Not repeatable, but this never happened with the previous 2.7.0 build.

Maybe related to different versions of Node? 🤷

For me, this is sadly happening quite frequently.

In https://github.com/parcel-bundler/parcel/pull/8625, I noticed another error related to rebuilding (but I think it's related to ESM and not on windows).

See https://github.com/parcel-bundler/parcel/pull/8625#issuecomment-1312589932

[Elias-Graf]

Not repeatable, but this never happened with the previous 2.7.0 build.

For me, it does very much happen also with older builds.

[mischnic]

How can I reproduce this on Windows?

[Elias-Graf]

@mischnic I'm honestly not sure, it's really inconsistent. I can tell you exactly what I'm doing, though:

1. Open Windows terminal
2. parcel serve <path to html>
3. Open a new tab in Windows terminal
4. Edit the file using the helix-editor

I've just tested and the same thing does seem to happen when using VS Code instead of the helix-editor.

[roddypratt]

@mischnic I'm honestly not sure, it's really inconsistent.

This. It's not always repeatable but I get it once or twice a day. Steps are as above. AFAICT editing any file that causes parcel to do rebuild/HMR may cause the issue.

You could try making a script that repeatedly modifies one of the HTML/JS assets and see if that triggers it?

I'm using Windows 11, VSCode 1.73.1

[scottgarner]

I can reproduce this consistently by rapidly hitting ctrl-S twice to save in VSCode after making a change that would trigger a rebuild.

[partyvaper]

Can consistently repeat this issue in Win 11, with latest Parcel version (2.8.1) and Node 16, Node 19, quite annyoing, quickly writing, saving, deleting few chars, saving again in html file, instantly introduces this issue

Never experienced this on macOS with same project.

I have tried removing, enabling HMR, changing config, passing various flags, basically no success. Maybe there is some flag to bypass all cache and random file names, as a quick workaround?

Might be solved with https://github.com/parcel-bundler/parcel/pull/8616/

---

After applying changes from https://github.com/parcel-bundler/parcel/pull/8616/ as yarn patch, it seemed to improve, but now I got another error:

× Build failed.

@parcel/compressor-raw: EPERM: operation not permitted, rename D:\test\dist\index.html.12768.5c' -> 'D:\test\dist\index.html'

  Error: EPERM: operation not permitted, rename 'D:\test\dist\index.html.12768.5c' -> 'D:\test\dist\index.html'

[andrew-rinato]

Dropbox file sync was the culprit for me.

[IMGROOT2]

Disabled OneDrive sync but to no avail. Still the same issue.

[HelloJesus]

i tried this writeStream.once("error", () => { failed = true; fs.unlinkSync(tmpFilePath); try { fs.unlinkSync(tmpFilePath); } catch (e) { // ignore error } }); in file @parcel\fs\lib\index.js:1020 but i got:

    fs.unlinkSync(tmpFilePath);
            ^
ReferenceError: fs is not defined

Or what is the right way to make changes from github?

i wrote this: "start": "parcel ./src/index.html --no-cache", and maybe it's work

[HelloJesus]

Disabled OneDrive sync but to no avail. Still the same issue.

check this => "start": "parcel ./src/index.html --no-cache"

[IMGROOT2]

Same error, same frequency (every other rebuild)

[Cristy94]

Save error, parcel keeps on crashing on rebuilding (maybe when I save twice?):

[IMGROOT2]

This is the exact error I get, as well. I’m also on Windows 11. I did some testing and found out this never happens when Parcel is run on a cloud server (GitHub Codespaces, Gitpod). Does that help?

[tikato]

Happening for me as well (VSC 1.77.0). Running Node v18.12.0 and it crashes randomly when I update a file (html, js, scss).

[xamasistemas]

We made a workaround. We created a 'cleanup' script who celan the .parcel-cache and dist folder.

"scripts": {
    "cleanup": "rimraf .parcel-cache dist",
    "dev": "npm run cleanup && parcel ./src/index.html --no-cache",
    "prebuild": "npx rimraf build",
    "build": "parcel build --public-url ./ ./src/index.html --no-cache"
  },

maybe the problema is concurrency and file lock in the .parcel-cache folder

[Elpatii]

Same for me.

Occurs every time after 3 saves of my index.html.

Run with --no-cache doesn't help, nor cleaning up .parcel-cache and dist folder. No problem with Parcel 2.7.0.

Software	Version
Parcel	2.8.3
Node.js	20.0.0
npm	9.6.4
Operating System	Windows 11 Pro 22H2

[Cristy94]

Still happens for me in the latest nightly version (2.0.0-nightly.1293).

[DarrenDanielDay]

Same problem on Windows 10, really annoying.

But it seems parcel won't crash if I only edit & save HTML files that are not page entries. Currently I try to avoid this problem by changing the HTML files I edit from page entry files to files imported as text bundle.

<!-- the entry HTML file, like `index.html`, that I would never edit after parcel started -->
<script type="module" src="./proxy.js"></script>

// proxy.js
import html from "bundle-text:./the-page-content.html";

document.open();
document.write(html);
document.close();

./the-page-content.html is the real HTML content file that I would edit frequently, and parcel would not crash when I save the-page-content.html.

Is this behavior useful to help find out the bug?

[tones31]

I have the same problem. All I did was start up a brand new parcel project and install tailwindcss following their guide on using it with parcel. It ran fine. Then I deleted "hello world" from the HTML file and it crashed

I can reproduce it every time. Just run npx parcel src/index.html and modify the HTML file two times. I also have auto save on VS code.

[xGeekoo]

Do we have any fix for that ?

[lexuzieel]

This issue still happens for me as well. Any ETA for a fix?

[benyrfg]

I have the same issue.

[Cristy94]

Ok, found a way to reproduce the crash with Error: ENOENT: no such file or directory, unlink:

• Have parcel running
• Have the website open in your browser
• Have DevTools open with "Pause on uncaught exceptions"
• Introduce an exception error in your code (e.g. console.log(undefined_variable))
• Save the file (so the app is reloaded and the browser pauses)
• Fix the error (remove the exception) and save the file again
• Because the app compiles BUT the browser JS execution is still paused (on debugger), Parcel crashes for some reason:

Error: ENOENT: no such file or directory, unlink 'C:\wamp64\www\userTrack\dist\index.2d3ace14.js.20660.3q'
    at Object.unlinkSync (node:fs:1883:3)
    at WriteStream.<anonymous> (C:\wamp64\www\userTrack\node_modules\@parcel\fs\lib\index.js:1028:83)
    at Object.onceWrapper (node:events:629:26)
    at WriteStream.emit (node:events:526:35)
    at emitErrorNT (node:internal/streams/destroy:151:8)
    at emitErrorCloseNT (node:internal/streams/destroy:116:3)
    at process.processTicksAndRejections (node:internal/process/task_queues:82:21) {
  errno: -4058,
  syscall: 'unlink',
  code: 'ENOENT',
  path: 'C:\\wamp64\\www\\userTrack\\dist\\index.2d3ace14.js.20660.3q'
}

So, to trigger the crash in 2 seconds, with dev tools open and "Pause on exceptions on", add this line console.log(undefined_variable), save the file, comment the line, save the file again.

[kumaramit24apps]

Same issue with me also. Whenever I try to change something in the html file it simply crashes every time. I tried everything but couldn't fix. What could be the possible reason? I tried using pnpm instead of npm, still stuck in that loophole.

[kumaramit24apps]

I was able to fix this crashing problem by merely fixing my content configuration inside tailwindcss.config.js file. It seemed to crash when it was unable to find the specific path I wrote inside the content property. So, I did the following to fix the issue:

/** @type {import('tailwindcss').Config} */
module.exports = {
-     content: ["./*.html"],
+    content: ["./src/**/*.{html, js, tsx, jsx, ts}"],
  theme: {
    extend: {},
  },
  plugins: [],
}

[HenkVanMaanen]

We had the same problem. The solution was to recursive chown the src directory to the current user so that the permissions of all files are fixed.

chown -R $(id -u):$(id -g) .
