Fixing Claude Code (1.0.51/1.0.45) in Git Bash

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.
