小编kim*_*imh的帖子

我正在使用git子模块,git submodule update --init --recursive命令很慢(8秒),虽然似乎没有更新要更新.

我想调试它为什么慢,但似乎没有--verbose开关.有没有想过要调试它在做什么？

我正在运行Ubuntu 14.04和Git 1.9.

我一直在使用以下命令安装abi直到今天.

echo y | android update sdk --no-ui --all --filter sys-img-armeabi-v7a-android-23

但现在我收到了以下错误.

Error: Ignoring unknown package filter 'sys-img-armeabi-v7a-android-23'
Warning: The package filter removed all packages. There is nothing to install.
Please consider trying to update again without a package filter.

有人有同样的问题吗？我正在使用Android SDK r24.4.1.

当我(println (iterate inc 0))在我的repl中运行时,我会得到这样的东西:

user=> (println (iterate inc 0))
(0 1 2 3 4 5 6 7 8 9 10 11 12 13 ....................

我运行代码的期望是repl什么都没显示,只是因为(iterate inc 0)永远不会结束而卡住了.但是,我明白了(0 1 2 3 ....

(iterate inc 0)产生永不回归的无限序列.如果它永远不会结束,那为什么要println开始印刷价值？

换句话说,(println xx)即使输入从未完成评估,为什么开始评估？

我有Android项目,当运行./gradlew dependencies命令时,我收到以下错误,我无法弄清楚如何使用Google Play Service 8.4.0.(8.3.0作品)

FAILURE: Build failed with an exception.

以下是app gradle文件的外观.

  dependencies {
      ....
      compile 'com.google.android.gms:play-services:8.4.0'
      ....
  }

我已经尝试将以下内容放在项目gradle文件中,但没有帮助.

    dependencies {
      classpath 'com.android.tools.build:gradle:2.0.0-alpha3'
      classpath 'com.google.gms:google-services:2.0.0-alpha3'
    }

任何人都可以帮助我进一步调试吗？

是否可以有这样的多行键？

mykey:
  - >
    key
    one:
    keytwo: val

其中 keyone 被视为一把钥匙。我想解析 yaml 以产生：

{ mykey: [ { keyone: { keytwo: val } } ] }
