我sudo pacman -Syu在Archlinux上运行,我得到以下内容:

cristian@localhost:~$ sudo pacman -Syu
:: Synchronizing package databases...
 core is up to date
 extra is up to date
 community is up to date
 multilib is up to date
 xenlism-arch is up to date
:: Starting full system upgrade...
resolving dependencies...
looking for conflicting packages...
error: failed to prepare transaction (could not satisfy dependencies)
:: package-query: requires pacman<4.3

解决这个问题的解决方案是什么？

UPDATE

我尝试了@jham提取的两种解决方案.我已经完全删除了yaourt和package-query.在pacman -Qi pacman'必需'我有none.我还评论了multilib和xenlism-arch pacman.conf.当我这样做时,pacman -Syu我得到以下内容:

我有以下服务:

import { Injectable } from '@angular/core';

import { MenuItem } from './../classes/menu-item';
import { ITEMS } from './../static-data/items-list';

@Injectable()
export class ItemsListService {

    getItems(): Promise<MenuItem[]> {
        return Promise.resolve(ITEMS);
    }

}

这项服务的测试在这里:

import { TestBed, async, inject } from '@angular/core/testing';

import { ItemListService } from './item-list.service';
import { MenuItem } from './../classes/menu-item';
import { ITEMS } from './../static-data/items-list';

describe('ItemListService', () => {
  beforeEach(() => {
    TestBed.configureTestingModule({
        providers: [ ItemListService, MenuItem, ITEMS ]
    });
  });

  it('should ...', inject([ItemListService], (service: ItemListService) => …

是否有快捷键来关闭标签？
我要求创建选项卡之类的CTRL b + c
东西如果我要关闭1:cmatrix*选项卡,我应该使用哪种快捷方式？

无法弄清楚它的[3]数量是多少.

我正在构建一个3d css立方体菜单.代码在这里.

<button id="btn">flip button</button>    
<div class="signup-viewport">
    <div id="cube" class="cube animation">
        <div class="front">front <a href="">front link</a></div>
        <div class="back">Back</div>
        <div class="left">Left</div>
        <div class="right">Right <a href="">right link</a></div>
        <div class="bottom">Bottom</div>
        <div class="top">Top</div>
    </div>
</div>

当通过"翻转按钮"按钮翻转面部时,无法单击立方体右侧的链接.

有什么想法吗？在Firefox中链接工作,但铬和铬没有.

我有以下字符串：

String json = "[{\"id\": \"0\", \"ip\": \"123\", \"mac\": \"456\"}, {\"id\": \"1\", \"ip\": \"111\", \"mac\": \"222\"}]";

还有一个 SlaveEntity 实体，它具有：

public class SlaveEntity extends BaseEntity {

    private String ip;
    private String macAddress;
    private String status;

    @OneToMany(mappedBy="slave", targetEntity = PositionEntity.class, fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    private List<PositionEntity> positions;

}

我正在编写一个接受 json 并返回一个 SlaveEntity 列表的方法：

public static List<SlaveEntity> JsonToSlaveEntity(String json) {
        ObjectMapper objectMapper = new ObjectMapper();
        List<SlaveEntity> obj = new ArrayList<SlaveEntity>();

        try {
           obj = objectMapper.readValue(json, List.class);

        } catch (IOException e) { …

有人可以帮忙吗？

HTML:

<div>Hello</div
<my-custom-el>content</my-custom-el>

该<my-custom-el>可一次<my-custom-el>,其它时间<his-custom-el>等...

有没有办法在css之后选择元素<div>,而不知道DOM元素类型是什么？

我有以下表格:

如果我点击星号,输入将自动填充所点击的星号.(单击第3颗星,输入将填充数字'3',如下图所示)

明星的输入是ng-required="true".

<form name="completeSurveyForm" role="form" novalidate ng-submit="vm.save()">
    <ul class="question-list">
        <li data-ng-repeat="question in vm.survey.questions | orderBy:'conditionalOrderId' track by question.id ">
            <small class="label label-primary pull-right">{{question.questionTypeName}}</small>
            <h3>
                <b>{{$index +1 }}.</b>&nbsp;{{question.questionBody}}
            </h3>
            <hr> <!-- Replace here with directives -->
            <div data-ng-switch="question.questionType">
                <numericrange question="question" data-ng-switch-when="NUMERIC_CHOICE" />
            </div>
        </li>
    </ul>
    <button type="submit" ng-disabled="completeSurveyForm.$invalid " class="btn btn-primary">
        <span data-translate="fqApp.business.form.submit">Submit</span>
    </button>
</form>

而numericrange指令如下所示:

<div class="row">
    <div class="col-md-2" ng-if="!completed">
        <div>
            <span ng-mouseover="showHovered($event)" ng-mouseleave="clearStars($event)" ng-click="selectStar($event)"
                data-ng-repeat="sym in range(startNonActive(question), question.maxValue, 1)" class="{{question.symbol}} starred-element" value="{{$index}}">
            </span>

            <input type="number" name="{{question.id}}" …

假设有一个名为"my-folder"的文件夹,其中包含100个文件.如果我们要在所有100个文件中替换(不是在文件名中,而是在实际文件中)字符串"originalString"和"replacementString"什么命令应该完成这项工作？

尝试:
grep -rl matchstring ~/my-folder | xargs sed -i 's/originalString/replacedString/g'

find ~/my-folder -type f -exec sed -i 's/originalString/replacedString/g' {} \;

我也在stackoverflow上读过这个.

这些都不适合我.我拼写错了？顺便说一下,我在linux上.

我有这个main-navbar组件。

app /templates/components/main-navbar.hbs文件如下所示：

<ul>
    <li>Home</li>
    <li>Blog</li>
</ul>
<button> Add class </button>

当我单击按钮时，我希望ul元素接收测试类<ul class='test'>，当我再次单击按钮时，测试类将被删除。

我怎样才能实现按钮的这个动作？我假设必须使用app/components/main-navbar.js文件。
