child_process.spawn ENOENT錯誤

Question

我有這樣

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機，我的一些函數具有相同的錯誤：ENOENT試圖執行NPM。它存在於process.env.PATH中。我做錯了什麼？

P.S. somedir已定義並等於現有目錄

對不起，夥計們，這是我的錯。 somedir不存在。關閉問題
