如何使用Git bash为以太坊索引器设置环境变量?

我正在学习本教程 https://github.com/getamis/eth-indexer/blob/master/README.md

    git config --global user.name "username"
    git config --global user.password "paswd"
    git clone https://github.com/username/eth-indexer.git
    cd eth-indexer
    touch .env
    echo "MYSQL_DATA_PATH=~/indexer-data/mysql" > .env
    echo "GETH_DATA_PATH=~/indexer-data/geth" > .env
    git add .env
    git add -f .env
    docker-compose build
