There's a manual workaround!
有一个手动解决方法！
As per post https://stackoverflow.com/a/42733510/7694425:
根据帖子https://stackoverflow.com/a/42733510/7694425：
- Download the command line tools, place them in the SDK folder (e.g., on mac: /Users/user/Library/Android/sdk), and then add the bin folder to the PATH.
- Install the latest platform: in a terminal, execute sdkmanager "platforms;android-25"
- Open Android Studio, and go to the SDK Manager (Appearance and Behavior > System Settings > Android SDK)
- Click on "Edit", and then select the sdk folder. Then "Next" > "Next" > "Finish".
- 下载命令行工具，将它们放在 SDK 文件夹中（例如，在 mac 上：/Users/user/Library/Android/sdk），然后将 bin 文件夹添加到 PATH。
- 安装最新平台：在终端中，执行 sdkmanager "platforms;android-25"
- 打开Android Studio，进入SDK Manager（Appearance and Behavior > System Settings > Android SDK）
- 单击“编辑”，然后选择 sdk 文件夹。然后“下一步”>“下一步”>“完成”。
Still, it doesn't resolve the missing emulator package therefore the Android SDK tools can't be updated since it's a dependency. But Android studio works and you can download other packages.
尽管如此，它并没有解决丢失的模拟器包，因此无法更新 Android SDK 工具，因为它是一个依赖项。但是 Android Studio 可以工作，您可以下载其他软件包。
Looking forward to a better solution.
期待更好的解决方案。

Solution to emulator package issue!
模拟器包问题解决！
After digging in the repo's XML for a while I've spotted the issue.
在研究了 repo 的 XML 一段时间后，我发现了这个问题。
It turns out that the "emulator" package is only in channel 3 (canary) while the "tools" package is in channel 0 (stable) but depends on "emulator". The solution is to force the manager to download the "emulator" package from channel 3:
事实证明，“模拟器”包仅在通道 3（金丝雀）中，而“工具”包在通道 0（稳定）中，但取决于“模拟器”。解决办法是强制管理器从通道3下载“模拟器”包：
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 libbz2-1.0:i386
Problem solved!

After lot of struggling I made it work. Here my solution
经过很多努力，我使它工作。这是我的解决方案
When I get the "An error occurred while trying to compute required packages" error I just clicked "finished" and then I went to the main Android Studio page:
当我收到“尝试计算所需的包时发生错误”错误时，我只是单击了“完成”，然后转到了主 Android Studio 页面：
Then I selected Configure -> SDK manager and I launched the SDK installation from there
然后我选择了配置 -> SDK 管理器，然后我从那里启动了 SDK 安装
Reopened Android Studio and everything was ok
重新打开 Android Studio 一切正常
Really, really embarrassing for a software which used to be very good. You can feel the "bloatness" of Eclipse creeping in
真的，对于一个曾经非常好的软件来说真的很尴尬。你可以感受到 Eclipse 的“臃肿”蔓延
回答by Vladimir Panteleev
I was getting this error on Arch Linux because the SDK setup wizard ran out of space on /tmp, which is a tmpfs.
我得到这个错误在Arch Linux的，因为SDK安装向导运行的空间了/tmp，这是一个tmpfs。
Another question with a similar error and same possible cause: Android studio- “SDK tools directory is missing”
另一个具有类似错误和相同可能原因的问题：Android studio-“SDK 工具目录丢失”
