我在Angular2教程中遇到以下错误.TNS医生还可以,为什么会出现以下错误？

我需要从git中对我的angular2项目进行npm安装,但是使用tag = 6.0.0的标签.

例如

git git@github.com:akveo/ng2-smart-table.git
cd ng2-smart-table
git checkout tags/v0.6.0-0

我怎么做相当于:

  npm install --save PACKAGE_NAME




npm install git@github.com:akveo/ng2-smart-table.git#v0.6.0-0 
npm ERR! Darwin 16.4.0

为什么会出现以下情况？

我试图在python中使用协议缓冲区提交响应.以下是结构.

我在使用 Flask-babel 时遇到了问题。我无法创建日语翻译。

pybabel：错误：未知语言环境“jp”

这是 Flask-Babel 问题吗？

当一种语言不存在时，这是同样的错误。但是，德语作品。所以.....babel nit 支持日语吗？

有没有支持像日语这样的主要语言的 Babel 替代品？

我需要一个非常快的python中的树对象。查找的速度比内存更重要。叶节点是我想要的值。因此，如果给定 state=NY、postion=3、hourOfDay=2 和 dayOfWeek=3，我需要快速获得值 =100。带 * 的节点是叶节点。

0) root
    1) {state: [NY,LA]}
        2) {howOfDay:[1,2,3,4,5], postion:[1,2,3]}
                             *3) {dayOfWeek:[234]} => value:100
            4) {state: [FL,NV,……rest of the states]}
                5) {howOfDay:[1,6,7,8,9….23]}
                      *6) {dayOfWeek:[1,5,6,7]} => value:120

在我的数据库中，我的数据看起来像这样，属性为 json 对象。

parent child attribute value

0 1 state NY,LA
1 2 {howOfDay:[1,2,3,4,5], postion:[1,2,3]}
2 3 dayOfWeek dayOfWeek [2,3,4] 100
0 3 state  [FL,NV,……rest of the states]
4 5 howOfDay:[1,6,7,8,9….23]
5 6 dayOfWeek:[1,5,6,7] 120

那么，我应该使用什么 python 库和树结构来最好地找到一个值？如何将数据转换为最好的快速查找？

下面是 redis 的 dict 返回。为什么是b？我该如何摆脱它？

data = r_client.hgetall(key)
{b'test1:r': b'2', b'test2:f': b'2'}

print('test1:r' in data)
False

print(b'test1:r' in data)
True

当我从 redis 获取数据时，如何摆脱那个可怕的 b？

我的意思是我必须这样做才能得到我想要的：

new_data = {}
for key,value in data.items():
    new_data[key.decode()] = value.decode()

Go拒绝返回多个退货.如果我遗漏了第二次返回它可以工作,但我需要第二次返回.我该如何解决？

这是我的电话:

type Streaming struct{}

func main() {
    mySlice, dateList = getHgetallStreamingData()
}

这是我的功能:

func getHgetallStreamingData(pair string, c redis.Conn) ([]Streaming, []time.Time) {    
    var mySlice []Streaming
    var dateList []time.Time
    return mySlice, dateList
 }

这是我的错误:

multiple-value getHgetallStreamingData() in single-value context

我有一个循环，我从一个时间开始。时间和我要增加一分钟的时间。

 for idx := range keys {
    var a = idx * time.Minute
    var t = tInit.Add(time.Minute * a)
    fmt.Println(t, idx)


 }

这是我的错误

invalid operation: idx * time.Minute (mismatched types int and time.Duration)

请..有人可以解释一下吗？所以...... git pull不起作用.然后我指定要拉的分支.

git pull development

want to merge with, and 'branch.development.merge' in
