如何在 alpine linux 上运行 pstree？

我可以在 alpine linux 上以树的形式查看进程列表吗？我尝试使用 apk add，但它给出了一个关于无法满足的约束的错误。这个错误没什么帮助 :-(

/ # apk search pstools
WARNING: Ignoring APKINDEX.84815163.tar.gz: No such file or directory
WARNING: Ignoring APKINDEX.24d64ab1.tar.gz: No such file or directory

/ # apk search ps
WARNING: Ignoring APKINDEX.84815163.tar.gz: No such file or directory
WARNING: Ignoring APKINDEX.24d64ab1.tar.gz: No such file or directory

/ # apk add pstree
WARNING: Ignoring APKINDEX.84815163.tar.gz: No such file or directory
WARNING: Ignoring APKINDEX.24d64ab1.tar.gz: No such file or directory
ERROR: unsatisfiable constraints:

    required by: world[pstree]

感谢您的阅读。

以下命令对我有帮助：

/#     apk update 
fetch http://dl-cdn.alpinelinux.org/alpine/v3.6/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.6/community/x86_64/APKINDEX.tar.gz
