Scribbles for my bad memory

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!
