当我做了一个make时如何找到这个错误的问题我有这个错误信息:错误:(9,5)错误:资源android:attr/colorError not found

奇怪的是我有2个build.gradle文件:这里是我的build.gradle(Project:Projectname)文件:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

在这里我的build.gradle(模块:app)文件:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 22
    defaultConfig {
        applicationId "org.acme.nfcedit"
        minSdkVersion 22
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release { …

我是openstack热文件的新手.我做了搜索,但没有找到我的问题的相关答案.这里我的模板加热yaml文件:

heat_template_version: newton

description: Simple template to deploy a single compute instance with an attached volume

resources:   
   my_instance:
    type: OS::Nova::Server
    properties:
      name: instance-name
      flavor: std.cpu1ram1
      block_device_mapping_v2:
        - device_name: vda

  my_volume:
    type: OS::Cinder::Volume
    properties:
      size: 10

  my_attachment:
      type: OS::Cinder::VolumeAttachment
      properties:
        instance_uuid:  { get_resource: my_instance }
        volume_id: { get_resource: my_volume }
        mountpoint: /dev/vdb

这个加热文件有效,但我不知道如何将浮动IP附加到"my_instance".我能够在Horizo​​n内部完成它并且它在没有PB的情况下工作.在Horizo​​n界面下,我选择"Router_dmz"作为创建并允许浮动IP的池.据我所知,浮动IP地址应与"network-name.admin-network"相关联.我读了很多文档,我不知道是否要使用操作系统:Neutron :: FloatingIPAssociation资源或OS :: Nova :: FloatingIPAssociation.我试过了,我没有问题.

我有一个 5000 行的文件，我想要几个每个 200 行的文件，我尝试了以下方法：

#!/usr/bin/perl
use strict;
use warnings;
my $targetfile = '200_lines.txt';
my $filename = '5000_lines.txt';

open ( my $DATA, '<', $filename )  or die "Could not open file '$filename': $!";

while ( my $line = <$DATA> ) {
  my $counter++; 

  open (my $FILE, '>>', $targetfile ) or die "Could not open file '$targetfile': $!";
  print $FILE $line;
  close $FILE;
  if ( $counter % 200 == 0
    if ($. % 200 == 0) { 
      $targetfile =~ s/200/$counter/;
    } …
