尝试在Yii2中运行phpunit时出现Cygwin问题

我试图在Yii2基本安装中运行phpunit，但每当我从命令行运行php vendor/bin/phpunit时，我得到以下输出:

注意:我使用的是Windows 7。

dir=$(d=${0%[/'']*}; cd "$d"; cd "../phpunit/phpunit" && pwd)
# See if we are running in Cygwin by checking for cygpath program
if command -v 'cygpath' >/dev/null 2>&1; then
        # Cygwin paths start with /cygdrive/ which will break windows PHP,
        # so we need to translate the dir path to windows format. However
        # we could be using cygwin PHP which does not require this, so we
        # test if the path to PHP starts with /cygdrive/ rather than /usr/bin
        if [[ $(which php) == /cygdrive/* ]]; then
                dir=$(cygpath -m "$dir");
        fi
fi
dir=$(echo $dir | sed 's/ /' /g')
"${dir}/phpunit" "$@"

谁能告诉我这里的问题是什么?我以前没有使用过phpunit，所以不确定发生了什么。
