nodejs在spawn中執行npm報錯 [Error: spawn ENOENT]” errors

描述： 上代碼

var ps = require('child_process').spawn("npm", ['install'], {
    stdio: 'inherit',
    cwd: srcPath
});

ps.on('error', function(err) {
    console.log(err);
});

ps.on('exit', function (err) {
    console.log('exit');
});

執行報[Error: spawn ENOENT]

 

原因，windows下npm執行名不同

解決方案

var ps = require('child_process').spawn(process.platform === "win32" ? "npm.cmd" : "npm", ['install'], {
    stdio: 'inherit',
    cwd: srcPath
});
