我尝试克隆这个仓库并运行bundle install.捆绑过程失败并抛出此错误:

我现在正致力于Ionic项目,我想要zipalign这个android-release-unsigned.apk文件.我按照Ionic的指南.

当我运行zipalign -v 4 /Users/zulhilmizainudin/Desktop/kl-parking/platforms/android/build/outputs/apk/android-release-unsigned.apk android-release.apk命令时,我收到-bash: zipalign: command not found错误.

这是zipalign在我的系统中的位置:

/Users/zulhilmizainudin/Library/Android/sdk/build-tools/21.1.2

我试图在其中复制zipalign并将其放入我的Ionic项目文件夹并再次运行zipalign命令.但仍然得到相同的命令没有找到.

我现在应该怎么做？

我找到了这个Bootstrap Select项目及其Rails的宝石.我想在select标签中实现搜索.

我检查元素,这里是HTML源:

<select class="selectpicker" data-live-search="true">
  <option>Hot Dog, Fries and a Soda</option>
  <option>Burger, Shake and a Smile</option>
  <option>Sugar, Spice and all things nice</option>
</select>

如何data-live-search="true"在表单中添加select标签？

我的表格选择:

<%= f.select :food_id, options_for_select(Food.all.map{|c| [c.name, c.id]}, f.object.food_id), {}, {class: "form-control selectpicker"} %>

我尝试过的:

<%= f.select :food_id, options_for_select(Food.all.map{|c| [c.name, c.id]}, f.object.food_id), {}, {class: "form-control selectpicker", data: "live-search"} %>

但它不起作用.

我的CDK文件中有以下代码块：

const artifactBucket = new s3.Bucket(this, "MyBucket", {\n  bucketName: "cdk-cws-pipeline-artifacts",\n  removalPolicy: cdk.RemovalPolicy.DESTROY,\n  versioned: true, // a bucket used as a source in CodePipeline must be versioned\n});\n\n// code omitted for brevity\n\nconst pipeline = new codepipeline.Pipeline(this, "Pipeline", {\n  artifactBucket: artifactBucket,\n  // code omitted for brevity\n});\n

一切都工作正常，直到我尝试删除堆栈。我收到这个错误：

Are you sure you want to delete: cdk-staging-CwsPipeline (y/n)? y\ncdk-staging-CwsPipeline: destroying...\n6:11:42 PM | DELETE_FAILED        | AWS::S3::Bucket             | MyBucketF68F3FF0\nThe bucket you tried to delete is not empty. You must delete all versions …

我是Go的新手,我现在用它构建一个简单的API:

package main

import (
    "encoding/json"
    "fmt"
    "github.com/gorilla/mux"
    "github.com/gorilla/handlers"
    "log"
    "net/http"
)

func main() {
    port := ":3000"
    var router = mux.NewRouter()
    router.HandleFunc("/m/{msg}", handleMessage).Methods("GET")
    router.HandleFunc("/n/{num}", handleNumber).Methods("GET")

    headersOk := handlers.AllowedHeaders([]string{"Authorization"})
    originsOk := handlers.AllowedOrigins([]string{"*"})
    methodsOk := handlers.AllowedMethods([]string{"GET", "POST", "OPTIONS"})

    fmt.Printf("Server is running at http://localhost%s\n", port)
    log.Fatal(http.ListenAndServe(port, handlers.CORS(originsOk, headersOk, methodsOk)(router)))
}

func handleMessage(w http.ResponseWriter, r *http.Request) {
    vars := mux.Vars(r)
    message := vars["msg"]
    response := map[string]string{"message": message}
    w.Header().Set("Content-Type", "application/json") // this
    json.NewEncoder(w).Encode(response)
}

func handleNumber(w http.ResponseWriter, r *http.Request) {
    vars := mux.Vars(r)

我是rbenv的新手(长时间使用RVM).今天我清理卸载我的RVM并安装rbenv.我设法安装Ruby 2.5.1没有任何问题.

但是当我bundle install今天尝试运行一个项目时,我收到以下错误:

'find_spec_for_exe': can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException)

看来我的捆绑安装已经破坏了一些东西,但我不确定是什么问题.运行gem install bundler有sudo没有解决的问题.

这是完整的痕迹:

我正在使用Bootstrap 3 创建一个简单的HTML模板.我检查中等大小的模板,看起来没问题.但是当我在更大的显示器(和更高的分辨率)中检查它时,我在转盘内的图像的右侧看到一些空白区域.

在我更新 CloudFlare DNS 设置以指向我的 Heroku 应用程序后，已经过去了 48 多个小时。自定义域现在可以正常工作，无需 https://。

但是当我尝试 https:// 版本时，我得到了这个：

这是我的 Heroku 自定义域设置：

这是我的 CloudFlare DNS 设置：

这是我的 CloudFlare SSL 设置：

最后，这是我的 CloudFlare 页面规则设置：

我遵循这个CloudFlare 指南并且不会跳过其中的任何步骤。

我在这里缺少什么？

我的应用程序（http）：http://beta.futurelab.my/

我的应用程序（https）：https://beta.futurelab.my/

我的 Heroku 应用程序：http://future-lab-production.herokuapp.com或者https://future-lab-production.herokuapp.com

我希望我的应用程序仅在整个站点范围内可用https://beta.futurelab.my/并强制使用 SSL。

请帮忙。
