我在安装全局节点模块时遇到问题,我在网上找到的所有内容都说解决方法只是添加-g.哪个不是问题.我认为这是一个链接问题或错误的目录问题.

这是我做的:

$ npm install -g express
npm http GET https://registry.npmjs.org/express
npm http 304 https://registry.npmjs.org/express
npm http GET https://registry.npmjs.org/range-parser/0.0.4
npm http GET https://registry.npmjs.org/mkdirp/0.3.3
...downloads correctly

$ express myapp
bash: express: command not found

但是,当我运行直接链接位置来表达它的工作原理时:

   $ /usr/local/share/npm/bin/express myapp

   create : myapp
   create : myapp/package.json
   create : myapp/app.js
... Builds app correctly

模块的位置是:

$ which node
/usr/local/bin/node
$ node -pe process.execPath
/usr/local/Cellar/node/0.8.20/bin/node
$ npm link express
/Users/bentonrr/Development/Personal/node_modules/express -> /usr/local/share/npm/lib/node_modules/express

在我的.bash_profile中,我有:

export PATH=/usr/local/bin:$PATH
export NODE_PATH=/usr/local/lib/node_modules:/usr/local/lib/node

我是否需要更改我的节点环境才能下载到正确的文件夹？是不是正确连接的东西？我搞不清楚了..

谢谢!

其他规格:

$ node --version
v0.8.20
$ …

我有aws文件夹作为插件

可能重复:
CSS:如何将列表分成页面上的列？

我一直在寻找这个解决方案而找不到它,所以我想我会发布我最终制作的内容.

我试图建立一个单独的列表,在第5项之后,列表将换行并移动到另一列.这是因为它可以是超级动态的,用户需要多少项.

这是我提出的解决方案.

 li{
   position: relative;
   line-height: -6px;
}
    
 ol li:nth-child(6) {
    margin-top: -90px;
}
    
 ol li:nth-child(-n+5){
    margin-left: 0em;
 }
    
 ol li:nth-child(n+6){
   margin-left: 10em;
 }

 <ol>
      <li>Aloe</li>
      <li>Bergamot</li>
      <li>Calendula</li>
      <li>Damiana</li>
      <li>Elderflower</li>
      <li>Feverfew</li>
      <li>Ginger</li>
      <li>Hops</li>
      <li>Iris</li>
      <li>Juniper</li>
 </ol>

你觉得我的解决方案怎么样？什么是适用于IE的解决方案？

我正在构建一个可访问的网站,并试图管理焦点.我需要打开一个模态,然后将焦点放在模态中的第一个元素上,然后捕获焦点,直到模态关闭("取消"或"接受").

HTML

<a href="" ng-click="modalshow = !modalshow; modal.open();">Open Modal</a>
  <div ng-show="modalshow" id="modal">
    <h3 id="tofs" >Terms of Service</h3>
    <p>Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum </p>
    <span>Cancel</span> 
    <span>Accept/span> 
  </div>
  <h2>Seprate Content</h2>

使用Javascript

angular.module('app')
    .controller('Controller', modalCtrl);

  function modalCtrl() {
     $scope.modal = {
       open: function() {
         angular.element('#tofs').focus();

       }
     }
  }

我似乎无法弄清楚这一点.当我打开我的React Native应用程序时,我得到了这些错误.我发现最好的是它与应用程序的捆绑方式有关.任何帮助将非常感谢和赞成!谢谢!

我有一个sails js app我试图在heroku服务器上启动.据我所知,heroku应用程序默认安装ruby而不是节点.

我有一个bower.json文件,一个package.json文件和一个Procfile.
