Scribbles for my bad memory

1.0.72 works well among all my terminals in Windows and Linux without any hacks. So please forget the fix in this article and try 1.0.72!
for version 1.0.51 or newer, you can simply add a new environment variable with CLAUDE_CODE_GIT_BASH_PATH=C:\Program Files\git\bin\bash.exe using Edit environment variables for your account feature on windows.

However, I stick with v1.0.45 for now, as I noticed 1.0.51 no longer support paste image in gitbash, which is a pity!

I just noticed this hack only works with version 1.0.45, so please stick with version 1.0.45 for now until we found another hack :D

Claude Code fails in Git Bash with path errors like:

Error: /usr/bin/bash: line 1: C:UsersDavid.WeiAppDataLocalTemp/claude-shell-snapshot-6ea5: No such file or directory

Root cause: os.tmpdir() returns Windows paths, Git Bash expects Unix paths.

Solution: Patch the CLI directly with sed.

# Create ~/bin/c
#!/bin/bash
REAL_CLAUDE=$(which claude)
basedir=$(dirname "$REAL_CLAUDE")
case `uname` in
    *CYGWIN*|*MINGW*|*MSYS*)
        if command -v cygpath > /dev/null 2>&1; then
            basedir=`cygpath -w "$basedir"`
        fi
    ;;
esac

CLAUDE_DIR="$basedir/node_modules/@anthropic-ai/claude-code"
CLI_FILE="$CLAUDE_DIR/cli.js"
BACKUP_FILE="$CLI_FILE.original"

# Backup once
if [ ! -f "$BACKUP_FILE" ]; then
    cp "$CLI_FILE" "$BACKUP_FILE"
fi

# Patch and run
cp "$BACKUP_FILE" "$CLI_FILE"
sed -i 's/\b\w\+\.tmpdir()/\"\/tmp\"/g' "$CLI_FILE"

cd "$CLAUDE_DIR"
exec node "cli.js" "$@"

chmod +x ~/bin/c
echo 'export PATH="$HOME/bin:$PATH"' >> ~/.bashrc

Now works:

c doctor
c --version  

The regex catches minified variable names. Patches fresh every run, so updates don't break it.

Can't paste images to Claude Code in your Linux terminal? Here's a one-minute fix for Kitty users.

The Fix

1. Create the script (~/bin/clip2path):

#!/usr/bin/env bash
set -e

if [ -n "$WAYLAND_DISPLAY" ]; then
    types=$(wl-paste --list-types)
    if grep -q '^image/' <<<"$types"; then
        ext=$(grep -m1 '^image/' <<<"$types" | cut -d/ -f2 | cut -d';' -f1)
        file="/tmp/clip_$(date +%s).${ext}"
        wl-paste > "$file"
        printf '%q' "$file" | kitty @ send-text --stdin
    else
        wl-paste --no-newline | kitty @ send-text --stdin
    fi
elif [ -n "$DISPLAY" ]; then
    types=$(xclip -selection clipboard -t TARGETS -o)
    if grep -q '^image/' <<<"$types"; then
        ext=$(grep -m1 '^image/' <<<"$types" | cut -d/ -f2 | cut -d';' -f1)
        file="/tmp/clip_$(date +%s).${ext}"
        xclip -selection clipboard -t "image/${ext}" -o > "$file"
        printf '%q' "$file" | kitty @ send-text --stdin
    else
        xclip -selection clipboard -o | kitty @ send-text --stdin
    fi
fi

2. Make executable:

chmod +x ~/bin/clip2path

3. Add to ~/.config/kitty/kitty.conf:

allow_remote_control yes
listen_on unix:/tmp/kitty-socket
map ctrl+v launch --type=background --allow-remote-control --keep-focus ~/bin/clip2path

4. Install dependencies:

# X11 users only
sudo apt install xclip

5. Restart Kitty

6. Setup automatic cleanup (optional):

# Add to crontab to clean old screenshots daily
(crontab -l 2>/dev/null; echo "0 3 * * * find /tmp -name 'clip_*' -type f -mtime +1 -delete") | crontab -

Now Ctrl+V automatically saves clipboard images as temp files and pastes their paths. Works on both Wayland and X11.

This post is out-dated. Claude code has now officially supported GitBash, see https://docs.anthropic.com/en/docs/claude-code/setup for detail.

Got a Windows dev VM where you can't install WSL? Here's how to get Claude Code working with just Git Bash.

The Fix

Add these to your .bashrc:

export NPM_CONFIG_IGNORE_SCRIPTS=true
export SHELL=/c/Program\ Files/Git/bin/bash.exe

Then:

source ~/.bashrc
npm install -g @anthropic-ai/claude-code

Done.

Why It Works

Git Bash provides enough Unix-like environment for Claude Code. The SHELL export tells it where to find bash, and NPM_CONFIG_IGNORE_SCRIPTS prevents install script issues.

Caveats

This is a workaround, not official support. Works fine in my vm, let me know if it also works on your machine!
