小编ver*_*joe的帖子

每当我创建项目时,我都必须下载节点模块的所有依赖项.在不复制node_modules的情况下,无论如何都要共享多个项目中的中心node_modules？

像下面这样,我每次都要运行很多命令..

npm install gulp-usemin                                                                        
npm install gulp-wrap
npm install gulp-connect
npm install gulp-watch
npm install gulp-minify-css
npm install gulp-uglify
npm install gulp-concat
npm install gulp-less
npm install gulp-rename
npm install gulp-minify-html

像下面一样,我跑步时出错了 mvn package

我是Python的新手.我安装了Python 2.7.10,它已经有了pip.我试图运行此命令来下载NumPy库.

D:\workspace\python>pip install numpy
Collecting numpy
  Could not find a version that satisfies the requirement numpy (from versions: )
No matching distribution found for numpy

但我得到了这个错误.我怎么解决这个问题？

我也想知道之间的区别easy_install和pip.

我是querydsl的新手.我看到了两种类型的querydsl实现.

有什么不同吗？我已经开发了com.mysema.query实现.但我认为我走错了路.请解释一下.

我的源代码如下.它有一个错误,"不能抛出DataAccessException类型的异常;异常类型必须是Throwable的子类".

我无法理解为什么错误发生了.让我知道.谢谢.

package com.sds.afi.cosmos.cmm.db.impl;

import java.sql.SQLException;
import java.util.HashMap;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.dao.DataAccessException;
import org.springframework.orm.ibatis.SqlMapClientTemplate;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
import org.springframework.stereotype.Repository;

import com.sds.afi.cosmos.cmm.db.MainDao;

@Repository
//@SuppressWarnings("unchecked")   // ???? ????? ??? ??
public class MainDaoImpl extends SqlMapClientDaoSupport  implements MainDao {

    @Autowired
    private SqlMapClientTemplate sqlMapClientTemplate;

    @SuppressWarnings("unchecked")
    @Override
    public List<HashMap> getUserInfo() throws DataAccessException {

        List<HashMap> lists;

        lists = sqlMapClientTemplate.queryForList("common.getList");

        return lists;
    }

}

我尝试通过brew install命令安装yum.但它没有使用下面的消息.问题是什么？我找不到任何好材料.

S0106602ad06e3352:ds jouk$ brew install "yum"
Error: No available formula with the name "yum"

Error: No similarly named formulae found.

我有三个问题!

第一.

我使用spring框架通过rest协议发送数据.

restTemplate.exchange(requestUrl,HttpMethod.POST, request, listVo.getClass());

org.springframework.web.client.RestTemplate.exchange(String url, HttpMethod method, HttpEntity<?> requestEntity, Class<? extends Object> responseType, Object... uriVariables) throws RestClientException

我没有任何问题地使用它,但我想知道参数responseType的用途.客户端不使用响应数据,而只使用响应状态代码/ msg.所以,我发送了一些毫无意义的String数据.但是他们接受"null"的错误被抛出.所以我发送了一个"null"字符串.不是空的.然后,错误摆脱了.但还有另一个问题.客户端从服务器收到数据并暂停了很长时间后.然后执行下一行代码.有什么问题？

第二

我找不到任何使用Spring RestTemplate的execute方法的引用.

第三

与标题一样,spring rest模板中的exchange方法和execute方法有什么区别？

感谢您的时间和精力.干杯.

我有一些代码如下.

MyRequests.cors_request("POST", 
        APP_CONFIG.APP_URL+"/users/selectAllUsers", 
        null, 
        function ok(users) {  

            $scope.usersNotFiltered = users;

            console.log('users--->', users);
            console.log('$scope.userPerSystem--->', $scope.userPerSystem);

            // delete the items that is already exists in the userPerSystem
            function filterUsers(element, index, array) {

                console.log("$scope.usersNotFiltered :: " + users);
                commonFindAndRemove($scope.usersNotFiltered, 'userId', element.userId);
                console.log('a[' + index + '] = ' + element.userId);
            }

            $scope.userPerSystem.forEach(filterUsers);

            $scope.users = $scope.usersNotFiltered;   
}, 

我运行代码并观看控制台.chrome控制台中'[Object]'和'[object Object]'有什么区别？

用户---> [对象,对象,对象,对象,对象,对象,对象,对象,对象,对象,对象,对象,对象,对象,对象,对象,对象]

$ scope.userPerSystem ---> [Object] 0:Objectlength:1__proto __:Array [0] redca-ias.concat.js:5258

$ scope.usersNotFiltered :: [object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object] ,[object Object],[object …

我有个问题.

在pom.xml中,依赖包含在两个地方.一个地方可以在<project>标签中,另一个地方可以在<plugin>标签中.

我认为标签中的依赖关系只与插件有关？这是对的吗？

提前致谢 :)

我想让 Jenkins 运行“执行 Windows 批处理命令”

运行此命令后，此命令将输出多行。这些行将在下一个构建步骤中使用，以便我想将它们保存到我的 Jenkins 环境变量中。

如何保存这些值？如果有其他方法，请告诉我。谢谢！
