Error message
[uninstall] Could not rewrite ${filePath}: What it means
After filtering out claude-mem alias lines, uninstall rewrites the rc file with writeFileSync (non-atomic, truncate-then-write). If the write throws, it warns and moves on, so the alias line stays. Because the write truncates first, a hard failure mid-write could leave the rc file partially written, so keep a backup of rc files before uninstalling.

// Claude Code's built-in auto-memory; on uninstall we restore the host

Solutions
- Run chmod u+w (and chown if needed) on the file from the message, then re-run uninstall
- Free disk space if the failure was ENOSPC
- Remove the `alias claude-mem =` line manually and restore the rc file from your dotfiles backup if it looks truncated
Defensive patterns
Strategy: validation
Validate before calling
import { accessSync, constants } from 'node:fs';
const rc = `${process.env.HOME}/.bashrc`;
try { accessSync(rc, constants.W_OK); }
catch { /* make it writable or remove the alias line yourself before uninstall */ } Type guard
function isErrnoException(error: unknown): error is NodeJS.ErrnoException {
return error instanceof Error && typeof (error as NodeJS.ErrnoException).code === 'string';
} Prevention
- Back up shell rc files before uninstalling: the rewrite is non-atomic truncate-then-write
- Ensure rc files are writable (chmod u+w) and not locked by sync clients
- Prefer removing the claude-mem alias manually when the file is managed by a dotfile tool
When it happens
Trigger: `npx claude-mem uninstall` rewrites ~/.bashrc or ~/.zshrc while the file is read-only, the filesystem is full, or another process (editor auto-save, sync client, indexer) interferes with the write.
Common situations: Read-only rc files; ENOSPC; files locked on Windows; heavily synced dotfiles where the sync client holds a lock during the rewrite.
