然后使用 nix develop 进入开发环境
或者，可以使用另一种写法，这样可以锁定 nixpkgs

其他可配置项目
见compose-android-packages
例如指定 cmake 版本

可能遇到的问题
Still waiting for package manifests to be fetched remotely

| Errors during XML parse:
Additionally, the fallback loader failed to parse the XML.
Still waiting for package manifests to be fetched remotely.

这是因为 gradle daemon 无法复用
关掉其他 daemon 即可
