child_process.spawn ENOENT错误

Question

我有这样

function startMain(){ 
    child_process.spawn(/^win/.test(process.platform) ? 'npm.cmd' : 'npm', ['install'], { 
     cwd : somedir, 
     stdio : 'inherit' 
    }).on('close',()=>{ 
     child_process.spawn('node', ['app'], { 
      cwd : somedir, 
      stdio : 'inherit' 
     }).on('error', (err)=>{ 
      console.log('Error occured during starting. Aborting...\nError stack: Cannot exec node\n'); 
      throw(err); // something wrong with spawn 
     }); 
    }).on('error', (err)=>{ 
     console.log('Error occured during starting. Aborting...\nError stack: Cannot exec npm\n'); 
     throw(err); // something wrong with spawn 
    }); 
} 

在Windows，Linux和Android机，我的一些函数具有相同的错误：ENOENT试图执行NPM。它存在于process.env.PATH中。我做错了什么？

P.S. somedir已定义并等于现有目录

对不起，伙计们，这是我的错。 somedir不存在。关闭问题
