帮助文档上面的安装教程太少了，一句带过，建议多出点可能发生的情况。

The issue names the anyproxy command and reports a missing node executable after installing AnyProxy 3.10 on Ubuntu 16.04. Reproduce the installation and command invocation first, then inspect the installation instructions. Done means the startup failure is addressed and the documented prerequisites and command behavior are clear.
