我最近尝试从Laravel 4.0升级到Laravel 4.1,运行php composer.phar update时出现以下错误:

Script php artisan clear-compiled handling the pre-update-cmd event returned with an error



  [RuntimeException]  
  Error Output:

我只要求:

"require": {
        "laravel/framework": "4.1.*",
        "way/generators": "2.*",
        "madewithlove/laravel-oauth2": "0.4.*"
    },

另外,我在错误之前收到了这个(即使我在我的环境中运行php 5.4.10):

phpseclib/phpseclib suggests installing ext-gmp (Install the GMP (GNU Multiple Precision) extension in order to speed up arbitrary precision integer arithmetic operations.)
phpseclib/phpseclib suggests installing pear-pear/PHP_Compat (Install PHP_Compat to get phpseclib working …

click事件工作正常,但onmouseover事件不起作用.

ProfImage = React.createClass({

    getInitialState: function() {
        return { showIcons: false };
    },

    onClick: function() {

        if(this.state.showIcons == true) {
            this.setState({ showIcons: false });
        }
        else {
            this.setState({ showIcons: true });
        }
    },

    onHover: function() {
        this.setState({ showIcons: true });
    },

    render: function() {

        return (
            <div>
            <span className="major">
                <img src="/images/profile-pic.png" height="100" onClick={this.onClick} onmouseover={this.onHover} />
            </span>


            { this.state.showIcons ? <SocialIcons /> : null }
            </div>

        );
    }

});

所以我尝试使用我的root密码(用户名:root密码:******)登录phpMyAdmin,但是,我继续收到错误:#2002无法登录MySQL服务器

我很确定我知道root密码,因为我在Mac OS X上输入了终端:

sudo /usr/local/mysql/support-files/mysql.server start

并被提示"Password:"一行.我键入了密码,终端读取:

Starting MySQL...SUCCESS! 因此服务器启动了.我不确定为什么相同的密码不适用于phpMyAdmin.

我尝试使用以下命令在终端中设置密码:

/usr/local/mysql/bin/mysqladmin -u root password *******

但是我收到了输出:

/usr/local/mysql/bin/mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)' 

我非常感谢帮助.我对此有所了解.我已经尝试了几个网站,而mySQL指令在这个问题上毫无用处.有关如何解决此问题的详细说明(在Mac OS X Lion上)将非常有用.谢谢.

更新:

我一直在尝试重置root密码,并且一直按照以下说明操作:http://www.coolestguyplanet.net/how-to-change-the-mysql-root-password/

但是,当我使用命令时:/ usr/local/mysql/bin/mysqld_safe --skip-grant-tables

我收到以下输出:

我想获得我在Laravel 4表单中设置的一系列复选框的值.以下是视图中设置复选框的代码:

@foreach ($friends as $friend)
<input tabindex="1" type="checkbox" name="friend[]" id="{{$friend}}" value="{{$friend}}">
@endforeach

在我的控制器中,我想获取复选框的值并将它们放在一个数组中.我不确定如何做到这一点,但我认为它是这样的:

array[];

foreach($friend as $x)
if (isset(Input::get('friend')) {
        array[] = Input::get('friend');

 } 
endforeach

你能帮我解决这个问题吗？谢谢.

编辑:

这就是我在控制器中的含义:

public function describe_favorite() {

            $fan = Fan::find(Auth::user()->id);
            $fan->favorite_venue = Input::get('venue');
            $fan->favorite_experience = Input::get('experience');

            $friends_checked = Input::get('friend[]');

            print_r($friends_checked);

            if(is_array($friends_checked))
            {
             $fan->experience_friends = 5;
            }

            $fan->save();


            return Redirect::to('fans/home');

        }

它没有经过"if"循环.如何查看print_r的输出以查看$ friends_checked变量中的内容？

我有一个Facebook登录我正在使用OAuth2执行,然后我使用Laravel 4的内置身份验证系统来重新登录用户.对于大多数用户,我认为没有任何问题,但对于一个用户,他看到登录时出现以下错误:

ErrorException

       public function login(UserInterface $user, $remember = false)
       {
               $id = $user->getAuthIdentifier();

以下是控制器中的相关登录/验证代码:

$check = Fan::where('fbid', '=', $user['uid'])->first();

                if(is_null($check)) {

                  $fan = new Fan;

                  $fan->fbid = $user['uid'];
                  $fan->email = $user['email'];
                  $fan->first_name = $user['first_name'];
                  $fan->last_name = $user['last_name'];
                  $fan->gender = $user['gender'];

我正在我的本地Mac OS X El Capitan机器上运行react-native应用程序.我已经安装了所需的依赖项,但该应用程序仍未在iOS模拟器中启动.

这是输出:

我正在尝试在我的Mac OS X机器上更新brew,以便我可以更新php.但是,在尝试运行时brew install,我收到此错误:

我试图在视图之间导航以在React Native中工作,如下所示:

newUserFlow() {
    this.props.navigator.push({
      title: "Create Account",
      component: F8InfoView,
    });
  }

<TopFiveButton
            style={styles.button}
            onPress={this.newUserFlow.bind(this)}
            caption="Create Account"
/>

但是,我在点击时遇到此错误:

ExceptionsManager.js:75 Argument 0 (NSNumber) of RCTNavigatorManager.requestSchedulingJavaScriptNavigation must not be null

这在以前工作,但似乎有些变化.可能是什么问题？谢谢.

调试器在例外manageR中引用它:

  // Flow doesn't like it when you set arbitrary values on a global object
  (console: any)._errorOriginal = console.error.bind(console);

我在打破流量吗？谢谢.

编辑:

index.ios.js看起来像这样:

class nomad extends Component {
  render() {
    return (
      <NavigatorIOS
        style={styles.container}
        initialRoute={{
          title: 'Nomad',
          component: LoginScreen
        }} />
    );
  }
};

然后在LoginScreen中:

class LoginScreen extends React.Component {
  newUserFlow() …

我有一个在false和true之间切换的某个变量作为一个状态(我们可以称之为提交).我想做的是在几秒钟之后将状态更改设置为true后将状态更改为false.我该怎么做？

我有一个单击按钮时调用的函数,以及状态更改的位置:

saveAndContinue: function(e) {
    e.preventDefault()

    if(this.state.submitted==false) {
        email = this.refs.email.getDOMNode().value
        this.setState({email: email})
        this.setState({submitted: !this.state.submitted});

    }

  }

我想补充一点,我有一个计时器设置变量提交回false.我该怎么做呢？
