【git】You‘ve successfully authenticated, but GitHub does not provide shell access.

ssh-Tgit@github.comHiYou'vesuccessfullyauthenticated,butGitHubdoesnotprovideshellaccess.并不是报错。ssh-Tgit@github.com命令后,您会收到以下消息:“HiYou’vesuccessfullyauthenticated,butGitHubdoesnotprovideshellaccess.”这条消息表示您的SSH认证成功,但GitHub不提供shell访问权限。这是因为GitHub是一个代码托管平台,主要用于版本控制和协作开发,而不是提供交互式的shell环境。您可以通过Git命令、API调用

The last packet sent successfully to the server was XXX milliseconds ago解决方案(Springboot+Mysql5.7)

android - Gradle 在 Ubuntu 13.10 上调用 "completing successfully with 1 error"

因此,当我在Ubuntu13.0464位上的AndroidStudio0.5.2上创建新项目并尝试在物理设备上运行它时,出现以下错误:Information:/home/juan/Documents/android-studio/sdk/build-tools/android-4.4.2/aapt:errorwhileloadingsharedlibraries:libz.so.1:cannotopensharedobjectfile:NosuchfileordirectoryError:Executionfailedfortask':app:mergeDebugResources'.

android - 斯卡拉+安卓 : Is anybody successfully building and debugging in Eclipse?

到目前为止,我能够在Eclipse中进行调试的唯一方法是将Treeshaker与ScalaIDE的错误2.8分支一起使用。如果我尝试在没有Treeshaker的情况下使用ScalaIDE进行构建,我会根据thislongthread收到ClassNotFound错误在scala-on-android上。理想情况下,我会使用sbt-android进行构建并在Eclipse中进行调试,但我一直无法成功地做到这一点。我能够实现的最接近调试sbt-android项目的是使用android:package-debug命令构建sbt-android项目,使用android:start-emulat

ios - PhoneGap : Successfully Opens, 的默认 ChildBrowser 插件示例但无法加载 URL

我希望这是一个很容易回答的问题,因为我似乎非常接近于让ChildBrowser插件正常工作。我正在使用Xcode4.6.2和Cordova2.7.0,试图创建一个运行通用ChildBrowser示例的基本iPhone应用程序。概览让我回顾一下到目前为止的步骤:1)从此处下载ChildBrowser插件:https://github.com/phonegap/phonegap-plugins/tree/master/iOS/ChildBrowser2)将所有.xib、.h和.m文件复制到Plugins文件夹。3)将ChildBrowser.js和index.html文件复制到www文件夹
