These按照说明在这台 Ubuntu 机器上安装 erlang-wx:

Operating System: Ubuntu 20.04.1 LTS
Kernel: Linux 5.4.0-48-generic
Architecture: x86-64

让 observer 运行还需要什么？

Answer 1

erlang-wx 包仅供通过 Ubuntu 包安装的 Erlang 使用，但您的包是使用 asdf 构建的。当您要求 asdf 构建 Erlang 时，它大概打印了这个:

 * wx             : wxWidgets not found, wx will NOT be usable

要解决这个问题，请安装软件包 libwxgtk3.0-gtk3-dev，然后删除并重新安装 asdf Erlang 安装。
