fluentd-ui start fail

This is my config info:

[root@Jasontom ~]# td-agent --version
td-agent 1.9.0

[root@Jasontom ~]# td-agent-gem --version
WARN: Unresolved specs during Gem::Specification.reset:

[root@Jasontom ~]# td-agent-gem install -V fluentd-ui

I'm seeing the same problem.
I have td-agent 1.9.2, running on Ubuntu bionic.

Is any log generated by fluentd-ui?

td-agent 1.9.0 or 1.9.2 seems too old, probably you mean td-agent 3.6.0 with fluentd-1.9.2.
(td-agent --version shows fluentd's version instead of td-agent package's version).

I confirmed this issue with td-agent 3.6.0.
The cause is that shebang of /opt/td-agent/embedded/lib/ruby/gems/2.4.0/gems/fluentd-ui-1.2.1/bin/fluentd-ui (which is the actual path of the executable) is inappropriate for td-agent:

#!/usr/bin/env ruby

A workaround for it is that adding /opt/td-agent/embedded/bin to your PATH:

sudo PATH=/opt/td-agent/embedded/bin:$PATH /opt/td-agent/embedded/lib/ruby/gems/2.4.0/bin/fluentd-ui start

The cause is that shebang of /opt/td-agent/embedded/lib/ruby/gems/2.4.0/gems/fluentd-ui-1.2.1/bin/fluentd-ui (which is the actual path of the executable) is inappropriate for td-agent:

#!/usr/bin/env ruby

The detail is incorrect.
/opt/td-agent/embedded/lib/ruby/gems/2.4.0/gems/fluentd-ui-1.2.1/bin/fluentd-ui is executed correctly by load.
But it fails to run bundler since it can't find the path.
