我正在尝试启动一个虚拟 android 设备,它是我使用 Android Studio 2.3 的 avdmanager 创建的(通过命令行)
所有命令都以root 用户 执行
当我尝试通过 $ ~/Android/Sdk/tools/./emulator @Nexus_5X_Api_23_x86 启动模拟器时,输出是:
emulator: ERROR: x86_64 emulation currently requires hardware acceleration!
Please ensure KVM is properly installed and usable.
CPU acceleration status: This user doesn't have permissions to use KVM (/dev/kvm)
我使用的是 64 位的 Ubuntu 16.04 服务器,Android Studio 是通过 x11 转发启动的,因此使用了我的桌面环境(也是 64 位的 ubuntu 16.04!)
当我输入 $ kvm-ok 时,它会给我:
INFO: /dev/kvm exists
KVM acceleration can be used
要证明我尝试访问的 .avd 存在:
$ ~/Android/Sdk/tools/bin/./avdmanager list avd
给出输出:
März 15, 2017 4:30:53 NACHM. sun.util.PropertyResourceBundleCharset$PropertiesFileDecoder decodeLoop

我真的不知道该怎么办了,搜索了整个论坛但没有在我的系统上找到这个问题的复制品,其他系统上相同问题的修复对我来说已经不起作用了,已经尝试完全清除并重新安装所有 qemu、libvirt、libvirtd 和 kvm 包,但没有成功。
感谢任何帮助!!

最佳答案
简单地试试这个。 这对我有用
$ sudo chown username -R /dev/kvm
有时你还需要运行这段代码
$ cd Android/Sdk/emulator/lib64/libstdc++
$ mv libstdc++.so.6 libstdc++.so.6.bak
$ ln -s /usr/lib64/libstdc++.so.6

我将应用程序升级到Rails4,一切正常。我可以登录并转到我的编辑页面。也更新了观点。使用标准View时,用户会更新。但是当我添加例如字段:name时,它不会在表单中更新。使用devise3.1.1和gem'protected_attributes'我需要在设备或数据库上运行某种更新命令吗?我也搜索过这个地方,找到了许多不同的解决方案,但没有一个会更新我的用户字段。我没有添加任何自定义字段。 最佳答案 如果您想允许额外的参数,您可以在ApplicationController中使用beforefilter,因为Rails4将参数

我意识到这可能是一个非常基本的问题,但我现在已经花了几天时间回过头来解决这个问题,但出于某种原因,Google就是没有帮助我。(我认为部分问题在于我是一个初学者,我不知道该问什么......)我也看过O'Reilly的RubyCookbook和RailsAPI,但我仍然停留在这个问题上.我找到了一些关于多态关系的信息,但它似乎不是我需要的(尽管如果我错了请告诉我)。我正在尝试调整MichaelHartl'stutorial创建一个包含用户、文章和评论的博客应用程序(不使用脚手架)。我希望评论既属于用户又属于文章。我的主要问题是:我不知道如何将当前文章的ID放入评论Controller。
