Question

我正在尝试使用yeoman自定义生成器搭建应用程序时启动git repo，这是我在install步骤中得到的：

  install: function () {
    this.installDependencies();
    this.spawnCommand('npm', ['i', '--save' , 'express', 'mongodb', 'mongoose', 'lodash', 'bluebird', 'async', 'morgan']);
    this.spawnCommand('git' ['init']); // Here fails
    this.spawnCommand('git', ['add', '.']);
    this.spawnCommand('git', ['commit', '-am', '"yo scaffolded app"']);
  }

然而，当我试图运行时，我得到：

events.js:85
      throw er; // Unhandled 'error' event
            ^
TypeError: Bad argument
    at TypeError (native)
    at ChildProcess.spawn (child_process.js:1136:26)
    at Object.exports.spawn (child_process.js:995:9)
    at spawn (/storage/home/dev/generator-koala/node_modules/yeoman-generator/node_modules/cross-spawn/index.js:87:19)
    at spawnCommand (/storage/home/dev/generator-koala/node_modules/yeoman-generator/lib/actions/spawn_command.js:17:10)
    at module.exports.yeoman.generators.Base.extend.install (/storage/home/dev/generator-koala/generators/app/index.js:72:10)
    at /storage/home/dev/generator-koala/node_modules/yeoman-generator/lib/base.js:421:16
    at processImmediate [as _immediateCallback] (timers.js:367:17)

我安装了git，我应该如何解决这个问题？

您没有使用回调，因此将spawnCommand更改为spawnCommandSync

install: function () {
    this.installDependencies();
    this.spawnCommandSync('npm', ['i', '--save' , 'express', 'mongodb', 'mongoose', 'lodash', 'bluebird', 'async', 'morgan']);
    this.spawnCommandSync('git' ['init']);
    this.spawnCommandSync('git', ['add', '.']);
    this.spawnCommandSync('git', ['commit', '-am', '"yo scaffolded app"']);
  }

尝试运行命令时，处理Yeoman自定义生成器中的错误事件
