“cordova run ubuntu”产生不完全应用 [英] "cordova run ubuntu" produces incomplete application

问题描述

我试图为ubuntu平台构建和运行cordova项目。该项目只是在创建新项目时自动生成的默认值。这里是config.xml文件（我添加了一行包含指向图标的链接）：

 <？xml version = '1.0'encoding ='utf-8'？> 
< widget id =com.gregory.exampleversion =0.0.1xmlns =http://www.w3.org/ns/widgetsxmlns：cdv =http：// cordova .apache.org / ns / 1.0>

当我在浏览器中查看index.html文件时，看到cordova标志，按钮，显示连接到设备。但是当我尝试使用CLI运行它，它不工作。

以下是我使用的命令：

  gregory @ gregory- 1001PXD：〜/ javascript $ sudo cordova create example com.gregory.example示例
创建一个新的cordova项目。 
 gregory @ gregory-1001PXD：〜/ javascript $ cd example / 
 gregory @ gregory-1001PXD：〜/ javascript / example $ sudo vi config.xml 
 gregory @ gregory-1001PXD：〜/ javascript / example $ sudo cordova platform添加ubuntu 
添加ubuntu项目... 
运行命令：/home/gregory/.cordova/lib/npm_cache/cordova-ubuntu/4.0.0/package/bin/ create / home / gregory / javascript / example / platforms / ubuntu com.gregory.example示例
创建Cordova项目：
项目路径：/ home / gregory / javascript / example / platforms / ubuntu 
软件包名称：com.gregory.example 
项目名称：示例
 
 config.xml中缺少图标元素
在config.xml中发现了插件cordova-plugin-whitelist。安装到项目
通过npm $ b $ fetching插件cordova-plugin-whitelist @ 1为ubuntu安装cordova-plugin-whitelist
 
此插件仅适用于版本的cordova-android大于4.0。如果你有一个以前的平台版本，你做*不需要这个插件，因为白名单将内置。
 
 gregory @ gregory-1001PXD：〜/ javascript / example $ sudo cordova build ubuntu 
运行命令：/ home / gregory / javascript / example / platforms / ubuntu / cordova / build 
构建桌面应用程序... 
为了构建debian包，执行：
 cd / home / gregory / javascript / example / platforms / ubuntu / native / com.gregory.example; debuild 
 gregory @ gregory-1001PXD：〜/ javascript / example $ sudo cordova run ubuntu 
运行命令：/ home / gregory / javascript / example / platforms / ubuntu / cordova / run 
构建桌面Application ... 
为了构建debian包，执行：
 cd /home/gregory/javascript/example/platforms/ubuntu/native/com.gregory.example; debuild 
 Build Successful。运行应用程序。 
运行Cordova 
启动应用程序。 
  

但是它说启动应用程序后，会弹出一个空白的灰色窗口，出现在侧边栏是一个问号。这里发生了什么？

解决方案

当我按照某人的答案回答我的另一个问题时，问题解决了：

无法找到'ANDROID_HOME'环境变量。无法在PATH中找到android命令

具体来说，这是一个权限问题。我通过反复运行

修复它

  cordova build ubuntu 
  

没有 sudo，然后，当有一个权限错误时，我让非root用户访问相关的文件或文件夹， p>

  sudo chown -R gregory /home/gregory/.cordova/lib/npm_cache/cordova-android/4.1.1/package/。这样做了好几次后，build命令最终没有错误地执行，然后
  
  cordova运行ubuntu 
  
成功。 
 
I'm trying to build and run a cordova project for the ubuntu platform.  The project is just the default that is produced automatically when I create a new project.  Here is the config.xml file (I added the line containing the link to the icon):
<?xml version='1.0' encoding='utf-8'?>
<widget id="com.gregory.example" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">
<icon src="img/logo.png" > </icon>

</widget>
When I view the index.html file in my browser, I see the cordova logo, and a flashing button that says "CONNECTING TO DEVICE."  But when I try to run it using the CLI, it doesn't work.  

Here are the commands I used:
gregory@gregory-1001PXD:~/javascript$ sudo cordova create example com.gregory.example Example
Creating a new cordova project.
gregory@gregory-1001PXD:~/javascript$ cd example/

missing icon element in config.xml
Discovered plugin "cordova-plugin-whitelist" in config.xml. Installing to the project
Fetching plugin "cordova-plugin-whitelist@1" via npm
Installing "cordova-plugin-whitelist" for ubuntu

This plugin is only applicable for versions of cordova-android greater than 4.0. If you have a previous platform version, you do *not* need this plugin since the whitelist will be built in.

But after it says "Launching the application," an empty gray window pops up, and the icon that appears in the sidebar is a question mark.  What is happening here?  
解决方案
This problem was solved when I followed someone's answer to another of my questions:

Failed to find 'ANDROID_HOME' environment variable. Failed to find 'android' command in your 'PATH'

Specifically, it was a permissions problem.  I fixed it by repeatedly running
cordova build ubuntu
without sudo, and then, whenever there was a permissions error, I gave my non-root user access to the relevant file or folder, e.g.
sudo chown -R gregory /home/gregory/.cordova/lib/npm_cache/cordova-android/4.1.1/package/.npmignore
After doing this several times, the build command eventually executed without errors, and then 
cordova run ubuntu
was successful.
