我已经阅读了Cannot install distribute: pypi.python.org rejecting http和Getting error 403 while installing package with pip，但解决方法并不适用
尝试时
<div class="task-manager_block" ng-controller="ToDoCtrl">
<div class="form_block clearfix">
<form name="addToDo">
<input class="add-input" placeholder="I need to..." type="text" name="inputToDo" ng-model="formTodoText" ng-model-instant ng-minlenght ng-minlength="5" ng-maxlength="40" ng-required="true"/>
<button class="add-btn" ng-click="addTodo()" ng-disabled="! addToDo.inputToDo.$valid "><h2>Add</h2></button>
</form>
</div>
<div class="tasks_block" ng-controller="DatepickerPopupCtrl">
<div class="task_block col-md-3" ng-repeat="todo in todos">
<div class="text_block">
<p class="input-group">
<input type="text" class="form-control" uib-datepicker-popup="{{format}}" ng-model="dt" is-open="popup1.opened" datepicker-options="dateOptions" ng-required="true" close-text="Close" alt-input-formats="altInputFormats" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="open1()"><i class="glyphicon glyphicon-calendar"></i></button>
</span>
</p>
<p>{{todo.text}}</p>
</div>
</div>
</div>
</div>
我得到了：
