Title: Installation fails with ERR_CHILD_PROCESS_STDIO_MAXBUFFER
during ripgrep step on Linux

Description:

Hi,
Claude CLI had been working fine for weeks, but suddenly it stopped
working and now the installation/update process fails on my Linux
machine. The error appears during the ripgrep step while the native
installer is being downloaded.

Relevant part of the logs:

2025-11-20T15:44:44.726Z [DEBUG] rg error (signal=undefined, code=ERR_CHILD_PROCESS_STDIO_MAXBUFFER, stderr: ), 171510 results
2025-11-20T15:44:44.726Z [ERROR] RangeError: Error
at <anonymous> (unknown)
at onData (node:child_process:153:110)
at emit (node:events:95:22)
at addChunk (internal:streams/readable:265:47)
at readableAddChunkPushByteMode (internal:streams/readable:243:18)
at handleNumberResult (internal:streams/native-readable:69:18)
at <anonymous> (internal:streams/native-readable:43:68)
at processTicksAndRejections (unknown:7:39)

Earlier in the logs I also see:

[ERROR] Failed to save config with lock: Error: ENOENT: no such file or directory, lstat '/home/dlopez/.claude.json'

I have also tried fully uninstalling Claude --- removing the binary
and deleting all configuration directories (~/.claude/ and
~/.claude.json) --- and reinstalling again using:

curl -fsSL https://claude.ai/install.sh | bash

...but the problem persists.

Environment

• OS: Linux
• Claude CLI previously working, now suddenly failing

Steps to reproduce

1. Run claude install or start Claude Code
2. The installer begins downloading the native installer
3. Ripgrep step runs and crashes with the above error

Expected behavior

The installation should complete normally without overflowing Node's
stdio maxBuffer.

Additional context

The logs show ripgrep producing 171,510 results, which may be
causing the buffer overflow. This never happened before, so something
may have changed in the installer or in how paths are scanned. Even
after a full uninstall and reinstall, the issue continues.

Let me know if you need more logs or want me to run a debug version.

What Should Happen?

finish installation without errors
