events.js：160扔呃; //未处理“错误”事件 – 错误：spawn npm ENOENT

操作系统：Windows 10专业版
节点：6.5.0
NPM：3.10.3
Gulp：CLI版本3.9.1

所以我在接收下面的错误，只在窗口，在runSequence （生成）过程中，当发射进程的runSequence 。 任何想法如何解决它？

 [14:44:57] Finished 'eslint-ci' after 18 s [14:44:57] Starting 'ava'... events.js:160 throw er; // Unhandled 'error' event ^ Error: spawn npm ENOENT at exports._errnoException (util.js:1026:11) at Process.ChildProcess._handle.onexit (internal/child_process.js:193:32) at onErrorNT (internal/child_process.js:359:16) at _combinedTickCallback (internal/process/next_tick.js:74:11) at process._tickCallback (internal/process/next_tick.js:98:9) 

代码如下：

 import runSequence from 'run-sequence'; gulp.task('to-html', done => { args.production = true; process.env.IS_SERVERLESS = true; const fetch = url => new Promise((resolve, reject) => { http.get({ host: 'localhost', path: url, port: 3000 }, res => { // Explicitly treat incoming data as utf8 (avoids issues with multi-byte). res.setEncoding('utf8'); let body = ''; res.on('data', data => { body += data; }); res.on('end', () => resolve(body)); }).on('error', reject); }); const moveAssets = () => { const assets = fs.readdirSync('build'); fs.mkdirSync(path.join('build', 'assets')); assets.forEach(fileName => { fs.renameSync( path.join('build', fileName), path.join('build', 'assets', fileName) ); }); }; const toHtml = () => { const promises = Object.keys(urls).map(url => fetch(url).then(html => { fs.writeFile(path.join('build', urls[url]), html); })); return Promise.all(promises); }; runSequence('eslint-ci', 'ava', 'flow', 'clean', 'build', () => { const proc = spawn('node', ['./src/server']); proc.stderr.on('data', data => console.log(data.toString())); proc.stdout.on('data', async data => { data = data.toString(); if (data.indexOf('Server started') === -1) return; try { moveAssets(); await toHtml(); } catch (error) { console.log(error); } finally { proc.kill(); done(); console.log('App has been rendered to /build directory.'); console.log('OSX tip: cd build && python -m SimpleHTTPServer 3000'); } }); }); }); 

ava.js

 import childProcess from 'child_process'; import gulp from 'gulp'; gulp.task('ava', done => { childProcess .spawn('npm', ['run', 'ava'], { stdio: 'inherit' }) .on('close', done); }); 

的package.json

  "ava": { "babel": "inherit", "files": [ "src/**/__test__/**/*.js" ], "source": [ "src/**/*" ], "require": [ "babel-register", "babel-polyfill" ] },
