node 执行报错： spawnSync /bin/sh ENOENT (mac环境)

Question

报错日志：

child_process.js:645
    throw err;
    ^
Error: spawnSync /bin/sh ENOENT
    at spawnSync (child_process.js:580:20)
    at Object.execSync (child_process.js:636:13)
    at Object.<anonymous> (/Users/abc/workspace/git/schedule/index.js:8:18)    

Answer 1

1. 搜了一下网上没有相关答案
2. spawnSync， ENOENT 了解到问题是跟文件目录或权限有关，但是mac环境, /bin/sh 的权限已经是-r-xr-xr-x 不能解决
3. 通过报错找到文件对应行

childProcess.execSync(`mkdir day`, {cwd: onlineCommonConf.backUp});

1. 将这行代码try,catch得到了更详细的报错，提示文件不存在

fs.js:646
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^

Error: ENOENT: no such file or directory, open '/opt/platform/data/data.json'
