question：Performance testing

[BigCatDi]

I want to test the performance of EMQ by using emqtt_bench . The testing environment has been installed. But after git clone https://github.com/emqx/emqtt-bench , "make code " tell me error. The web guidance don‘t describe error cause。
The error：
escript: exception error: no function clause matching
rebar_fetch:format_error({error,{hex_tarball,{tarball,eof}}}) (/opt/rebar3-3.11.1/src/rebar_fetch.erl, line 74)
in function rebar3:handle_error/2 (/opt/rebar3-3.11.1/src/rebar3.erl, line 339)
in call from escript:run/2 (escript.erl, line 758)
in call from escript:start/1 (escript.erl, line 277)
in call from init:start_em/1
in call from init:do_boot/3
Makefile:10: recipe for target 'compile' failed

Please tell me how to Slove it. Thank you !!

Hi @BigCatDi For this error log, I don't see where the problem is.

Can you paste the list of the commands you are executed and a version of the OTP? To make it easier for me to reproduce or understand the question.
