Question

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

所以我在gulp（构建）过程中，在触发进程的runSequence时，仅在Windows上收到以下错误。关于如何解决它的任何想法？：

＆＃13;

[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 _combinedTickCallback (internal/process/next_tick.js:74:11)
    at process._tickCallback (internal/process/next_tick.js:98:9)

＆＃13;

代码如下：

＆＃13;

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

＆＃13;

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

＆＃13;

的package.json

＆＃13;

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

＆＃13;

events.js：160 throw er; //未处理的错误＆＃39;事件 - 错误：产生npm ENOENT
