我尝试更新cordova和cordova-cli,但它没有用.

我正在用vueJS编写一个项目.我有一个包含以下代码的组件:

import ProjectsStore from './../stores/ProjectsStore.js';

export default {
    store: ProjectsStore,
    data () {
        return {
            loading: false,
            randomProject: null,
        }
    },
    computed: {
        projects () {
            return this.$store.state.projects;
        },
        commits () {
            return this.$store.state.commits;
        }
    },
    methods : {
        setCommit : ()=> {
            // code here
        }
    },
    watch: {
        projects: (value) => {
            this.setCommit()
        }
    },
    mounted () {
        this.$store.dispatch('loadProjectsList')
    }
}

我在项目中观察回调时出现以下错误:

this.setCommit is not a function

我放入一个console.log (this)回调函数,它显示一个默认对象而不是VueComponent.

我做错了什么？

谢谢你的帮助.

我正在研究python模块,我在Github上托管它.

对于测试,我尝试安装它pip.

我在这个问题和这个问题上尝试了几种方法.

每次我从运行中收到错误:

pip install git+git://github.com/amiceli/i2c-module

并输出:

Collecting git+git://github.com/amiceli/i2c-module
Cloning git://github.com/amiceli/i2c-module to /tmp/pip-HbjLru-build
No files/directories in /tmp/pip-HbjLru-build/pip-egg-info (from PKG-INFO)

要么

pip install https://github.com/amiceli/i2c-module

输出:

我有一个由 backgrid 生成的网格。

而且我想限制文本长度，每个 td 必须在一行上。

td 上的宽度属性无效。

谢谢你的帮助。

我正在尝试为ngFor.

每个项目必须在前一个项目之后几毫秒进行动画处理。

这是我的组件代码：

@Component({
    selector: 'bookmark-list',
    templateUrl: './bookmark.list.component.html',
    providers: [BookmarkService],
    styleUrls: ['./bookmark.list.component.less'],
    animations: [
        trigger('myAwesomeAnimation', [
            transition(':enter', [
                style({transform: 'scale(0.8)',}),
                animate('1.5s ease-out', style({transform: 'scale(1)',})),
            ]),
        ])
    ]
})

以及它的 html 标记：

<div class="col-sm-6 col-md-4 col-lg-3" *ngFor="let bookmark of bookmarks | bookmarkPipe:search">
  <div [@myAwesomeAnimation]='"large"'>
    <bookmark-item [bookmark]="bookmark"></bookmark-item>
  </div>
</div>

有没有办法将延迟作为角度转换的参数传递？

根据 Oluwafemi Sule 的回答，交错是解决方案：

    transition('* => *', [
        query(':leave', [
          stagger(
            100, [
              animate('0s ease-in-out', style({
                transform: 'scale(0.8)'
              }))
            ]
          )
        ], {optional: true}),
        query(':enter', [
          style({
            transform: 'scale(0.8)', …
