Android Can'；t在ubuntu上提供avd路径

我试图从控制台构建avd，但面临提供正确avd的问题

Cannot find AVD system path. Please define ANDROID_SDK_ROOT

或

这是列表avd返回给我的

    Name: Nexus_4_API_26
  Device: Nexus 4 (Google)
    Path: /home/dmitry/.android/avd/Nexus_4_API_26.avd
  Target: Google APIs (Google Inc.)
          Based on: Android 8.0 (Oreo) Tag/ABI: google_apis/x86
    Skin: nexus_4
  Sdcard: 100M

带路径的完整命令

dmitry@dmitry-H270-HD3:~/aosp/oreo$ sudo ./prebuilts/android-emulator/linux-x86_64/emulator -sysdir out/target/product/generic/ -system out/target/product/generic/system.img -ramdisk out/target/product/generic/ramdisk.img -data out/target/product/generic/userdata.img -kernel prebuilts/qemu-kernel/arm64/kernel -qemu-scale 0.7 -memory 2048 -partition-size 4096-verbose -avd Nexus_4_API_26

有什么想法吗？问题的根本原因是什么

这似乎是与最近更新有关的问题。临时解决方案是从命令行的/path/to/android sdk/tools目录中启动emulator

请看下面的问题
