react-native run-android通过在android仿真器中的消息中保留一条消息来终止。消息如下

无法加载脚本。请确保您正在运行Metro服务器，或者已正确捆绑了软件包“ index.android.bundle”以进行发布。

我完全感到困惑，这是在做错什么。

编辑：添加错误屏幕截图

1. 我刚刚安装了node.js和cli

   • 安装的node.js

   • 安装了react-native-cli

     npm -g react-native-cli
     

     Run Code Online (Sandbox Code Playgroud)

2. 并创建了一个“新项目”。

   react-native init new_project
   

   Run Code Online (Sandbox Code Playgroud)

3. 在“ new_project”目录中，我很疲倦地查看Metro bundler是否运行良好。

   react-native start
   

   Run Code Online (Sandbox Code Playgroud)

4. 但是该命令给了我以下错误，并且Metro无法启动。有任何解决此错误的线索吗？（我正在使用Windows 10 OS。）

   • 命令： C:\projects\new_proj>react-native start

我正在努力:http://flask.pocoo.org/docs/1.0/tutorial/

我在/ flaskr /目录中编写了__init__.py代码(这里是代码:http://codepad.org/4FGIE901),设置了一个名为'venv'的虚拟环境并安装了Flask.

然后我跑这些命令-在命令行上,在flaskr目录-为"运行应用程序"建议:( ,export FLASK_APP=flaskr,)export FLASK_ENV=developmentflask run

我应该看到的是 Hello, World!

相反,我遇到了以下错误:

Traceback (most recent call last):
  File "/Users/David/Desktop/flaskr/venv/lib/python3.6/site-packages/flask/cli.py", line 330, in __call__
    rv = self._load_unlocked()

  File "/Users/David/Desktop/flaskr/venv/lib/python3.6/site-packages/flask/cli.py", line 317, in _load_unlocked
    self._app = rv = self.loader()

  File "/Users/David/Desktop/flaskr/venv/lib/python3.6/site-packages/flask/cli.py", line 372, in load_app
    app = locate_app(self, import_name, name)

  File "/Users/David/Desktop/flaskr/venv/lib/python3.6/site-packages/flask/cli.py", line 246, in locate_app
    'Could not import "{name}".'.format(name=module_name)

flask.cli.NoAppException: Could not import "flaskr.flaskr".

简单地说,我不确定我应该如何回应或修复这样的错误.也许我在venv中安装的不匹配以及这个特定项目需要什么？

喜欢这个人:无法导入Pandas:TypeError

烧瓶:

• /Users/David/Desktop/flaskr/venv/bin/Flask …

def data = readJSON text: '{"rel" : {"configVersion": "1.0","manifest" :"'+"${manifestURL}"+'"}}'
writeJSON(file: 'C:\\Users\\Public\\json\\config.json', json: data)

我在我的jenkins管道中使用JSON函数并获取NoSuchMethodFoundError.我正在使用Jenkins 2.85.

知道如何解决这个问题吗？

我已根据以下说明在Mac OSX上安装并配置了git-credential-manager:

https://github.com/Microsoft/Git-Credential-Manager-for-Mac-and-Linux/blob/master/Install.md

brew安装抱怨缺少Java需求,并建议安装Java的命令,我做了.

完成所有操作后,我现在在尝试从私有存储库执行git克隆时出现以下错误:

Cloning into 'Weather'...
Fatal: java.lang.IllegalArgumentException encountered.  Details:

fatal: credential helper '!/Library/Java/JavaVirtualMachines/jdk-

有谁知道如何解决？

我按照以下链接开始使用react-native

React Native入门

我试图创建没有expo的本机应用程序，所以按照文档，我遵循以下命令

npm install -g react-native-cli
react-native init AwesomeProject

运行android命令后

react-native run-android

它给我以下模拟器错误

所以我用启动命令来运行Metro服务器

react-native start

这个命令给了我控制台另一个错误

我正在尝试执行Jenkins Pipeline中的代码示例:https://jenkins.io/doc/book/pipeline/docker/

node {
/* Requires the Docker Pipeline plugin to be installed */
    docker.image('maven:3-alpine').inside('-v $HOME/.m2:/root/.m2') {
        stage('Build') {
            sh 'mvn -B'
        }
    }
}

并告诉我这个错误:

[Pipeline] withDockerContainer
Jenkins does not seem to be running inside a container 
[Pipeline] // withDockerContainer

我不知道他为什么不做任何事情就这样停下来.

我已经在最新版本上安装了docker,docker plugin/docker管道.

在配置工具中,我添加了安装根路径.

我错过了什么 ？提前致谢

我正在尝试在 react-admin 项目中使用多个数据提供者，但出现错误：

Warning: Missing translation for key: "dataProvider is not a function"
function.console.(anonymous function) @ index.js:1452

我有我App.js这样的：

import React from 'react';
import { render } from 'react-dom';
import { Admin, Resource } from 'react-admin';
import dataProviders from './service/dataproviders';
import UserList1,  from './users1';
import UserList2,  from './users2';

const App = () => (
  render(
    <Admin dataProvider={dataProviders}>
      <Resource name="users1" list={UserList1} />
      <Resource name="users2" list={UserList2} />
    </Admin>,
    document.getElementById('root'),
  )
);

export default App;

我有dataproviders.js文件：

import simpleRestProvider from 'ra-data-simple-rest'; …

我的.Jenkins文件是这样的:

properties([[$class: 'GitLabConnectionProperty', gitLabConnection: 'gitlab@srv']])
node {
  env.JAVA_HOME = tool 'JDK 7'
  def mvnHome = tool 'Maven 3.2.2'
  def nodeJS = tool 'IA_NodeJS'
  env.PATH = "${mvnHome}/bin:${nodeJS}/bin:${env.JAVA_HOME}/bin:${env.PATH}"

  stage ('checkout') {
    checkout scm
  }

  stage ('build') {
    gitlabCommitStatus("build") {
      // your build steps
      sh 'mvn clean install -Denv=dev -P !faster'
    }
  }

  stage ('upload') {
    gitlabCommitStatus("upload") {
      def server = Artifactory.server "artifactory@ibsrv02"
      def buildInfo = Artifactory.newBuildInfo()
      buildInfo.env.capture = true
      buildInfo.env.collect()

      def uploadSpec = """{
        "files": [
          {
            "pattern": "**/target/*.jar",
            "target": "libs-snapshot-local"
          }, …

在我的package.json文件中,我声明了依赖项,其中一个来自公共注册表,另一个来自私有注册表(在本例中为Artifactory).

"dependencies": {
        "vue": "^2.4.4", //public registry
        "ce-ui": "http://myartifactory.com/artifactory/npm-local/ce-ui/-/ce-ui-0.0.2.tgz"
      }

我正在寻找使用插入符或tidle来声明依赖关系的方法,例如

 "dependencies": {
    "vue": "^2.4.4",
    "ce-ui": "^0.0.2"
  }

先感谢您.
