child_process 执行命令 git commit -m "test" 报错，请大大指教，感谢

var path = require('path'); var child = require('child_process'); var exec = child.exec; //提交暂存区的指定文件到仓库区 child.exec('/usr/bin/git commit -m "11111"', {cwd: '/Users/wangchengjun/www/yooli/femock'}, function(error, stdout, stderr){ if(error){ throw error; } console.log(stdout); });

Error: Command failed: /usr/bin/git commit -m "11111"
