我是Python开发的新手,我正在尝试在我的项目目录中安装virtualenv.

但是我有以下错误:

Installing collected packages: pip, setuptools

  Exception:

我正在尝试使用 VS 代码调试本地 uwsgi。不幸的是，我无法将 python 解释器附加到我的可视化代码调试中：

VSCode launch.json 配置：

{
        "type": "python",
        "request": "attach",
        "name": "Launch uWSGI",
        "port": 9090,
        "host": "127.0.0.1",
        "pathMappings": [
            {
                "localRoot": "${workspaceFolder}",  // You may also manually specify the directory containing your source code.
                "remoteRoot": "${workspaceFolder}" // Linux example; adjust as necessary for your OS and situation.
            }
        ]
    }

和uwsgi配置：

[development]
virtualenv = %(chdir)/../env/env1/
http = 127.0.0.1:9090

然后我在本地启用的 venv 中运行 uwsgi：

uwsgi --ini conf.d/uwsgi/dev.ini

输出如下：

detected max file descriptor number: 1024
lock engine: pthread robust …

我找不到一种方法来获取与通过Mandrill应用程序发送的一封电子邮件相关的所有统计数据？你使用Mandrill api来获取统计数据吗？

我有一些字符串,我想通过从开头和结尾删除所有非字母数字字符来清理.

它应该适用于这些字符串:

)&*@^#*^#&^%$text-is.clean,--^2*%#**)(#&^ --->> text-is.clean,--^2

-+~!@#$%,.-"^&example-text@is.clean,--^#*%#**)(#&^ --->> example-text@is.clean

我有这个正则表达式,它从整个字符串中删除它们:

val.replace(/[^a-zA-Z0-9]/g,'')

如何将其更改为仅从字符串的开头和结尾删除？

我知道Hbase会为每个插件保存一个时间戳.在谷歌BigQuery中是一样的吗？你怎么能访问它？

我正在尝试将变量验证为Angular控制器内的电子邮件.

var valid = $filter('email')($scope.email);

电子邮件过滤器不存在,生成"未知提供程序错误".从控制器内部访问电子邮件验证的正确方法是什么？

谢谢.

稍后编辑:不要让我创建自定义过滤器,它必须是一种使用角度验证的方式.

我需要在发送之前从Mandrill模板的所有链接添加一些参数.例如,在模板中有类似的锚点<a href="http://google.com>click here</a>".

我需要的是添加一个字符串(每个锚的一组参数),如下所示:<a href="http://google.com?param1=value1&param2=value2>click here</a>"动态

有没有办法通过API来做到这一点？类似于X-MC-GoogleAnalyticsCampaign的东西,它添加了utm_campaign参数.

我正在使用新的Angular路由器1.4,它为组件做一个简单的控制器时抛出一个错误:

angular.module('app.campaigns',['security', 'ngNewRouter'])
  .controller('CampaignsController', ['authService', '$rootScope', CampaignsController]);   


function CampaignsController (authService, $rootScope) {
    console.log ('this is campaigns controller');
    this.currentUser = $rootScope.authService.currentUser;
    this.authService = $rootScope.authService;
    this.logout = authService.logout;
}

我试过没有注入$ rootScope并且是一样的.我究竟做错了什么？一个非常相似的组件就像魅力一样,但事实并非如此.

我有以下代码连接到MongoDB:

try {
   $m = new Mongo('mongodb://'.$MONGO['servers'][$i]['mongo_host'].':'.$MONGO['servers'][$i]['mongo_port']);

 } catch (MongoConnectionException $e) {
   die('Failed to connect to MongoDB '.$e->getMessage());
 }

// select a database
$db = $m->selectDB($MONGO["servers"][$i]["mongo_db"]);

然后我创建了一个PHP类,我想在Mongo中检索/更新数据.我不知道如何访问之前创建的Mongo连接.

class Shop {
var $id;

public function __construct($id) {
    $this->id = $id;        
    $this->info = $this->returnShopInfo($id);
    $this->is_live = $this->info['is_live'];
}
//returns shop information from the database
public function returnShopInfo () {
    $where = array('_id' => $this->id);
    return $db->shops->findOne($where);
}
}

代码类似于:

$shop = new Shop($id);
print_r ($shop->info());

我有一个基于作为属性发送的数组构建html的指令。我无法从指令的编译器功能访问它。它在链接函数内部工作，但是我需要在编译内部，否则新模板不会被编译。

代码是这样的：

<multirangeslider values="ranges" variances="['Master', 'master A', 'master B']"></multirangeslider>

指示：

angular.module("vtApp.directives").
directive('multirangeslider', function ($parse, $timeout, $compile) {
    return {
        restrict: 'E',
        replace: true,
        scope: {
            values: "=",
            options: "=",
            variances: "&" 
        },
        compile: function (element, attrs) {
            var htmlText, variances, values;
            variances = eval(attrs.variances);

            values = scope.ranges //scope is undefined
            values = eval (attrs.variances) //returns string "ranges"
            values = ???  ///what should I put here?

            htmlText = '<div></div>';
            element.replaceWith(htmlText);
            return function (scope, element, attrs){

            }
        }
    }
});

谢谢
