Today is the 10th, and my Hugo site has been looked wrong. I forgot what I did to it, and it only deployed successfully once.

So today, I decided to fix it.

1 ¶

I checked the error log, and it showed:

sh: line 1: apt-get: command not found
Error: Command "apt-get update && apt-get install -y hugo" exited with 127

Although I’m not a professional programmer, I vaguely remembered that Vercel is a serverless platform whose build environment doesn’t provide a full Linux system, so it doesn’t support commands like apt-get.

I wasn’t exactly sure why this happened. When I worked with Hugo, most of the setup was done by a ChatGPT agent, so I suspected it had created a vercel.json file that modified the Vercel project settings.

So I went to Project Settings → Build & Development Settings and found these values (they were indeed set this way):

That fixed the first problem, but then second issue appeared:

Installing Hugo version 0.151.0    ← Hugo provided by Vercel
Installing dependencies...
+ hugo-bin 0.146.1                 ← hugo-bin is also installed in your project's package.json

I realized what was happening: the project was installing a different Hugo version because hugo-bin was listed in package.json (probably added by the ChatGPT agent).

So the solution was:

1. Open the project’s package.json.

2. Remove hugo-bin from devDependencies, for example:

   "devDependencies": {
     "hugo-bin": "..."
   }
   

3. Delete pnpm-lock.yaml (or your lockfile).

4. Re-run pnpm install (or npm install) locally.

Conclusion ¶

Finally, it worked. I’m exhausted.
