Description Timothée Floure 2019-02-06 08:13:31 UTC
Description of problem:
The erlang-rebar (= rebar2 library + executable) package is broken when the erlang-rebar3 package is installed


Steps to Reproduce:
1. install the erlang-rebar package
2. install the erlang-rebar3 package (from f30/rawhide)
3. run the `rebar` command (any parameter)

Actual results:


```
~ » rebar --version
Uncaught error in rebar_core: {'EXIT',
                               {undef,
                                [{rebar_config,new,[],[]},
                                 {rebar,init_config,1,
                                  [{file,"src/rebar.erl"},{line,126}]},
                                 {rebar,run,1,
                                  [{file,"src/rebar.erl"},{line,102}]},
                                 {rebar,main,1,
                                  [{file,"src/rebar.erl"},{line,58}]},
                                 {erl_eval,local_func,6,
                                  [{file,"erl_eval.erl"},{line,557}]},
                                 {escript,interpret,4,
                                  [{file,"escript.erl"},{line,789}]},
                                 {escript,start,1,
                                  [{file,"escript.erl"},{line,277}]},
                                 {init,start_em,1,[]}]}}
escript: exception error: undefined function rebar_utils:delayed_halt/1
  in function  erl_eval:local_func/6 (erl_eval.erl, line 557)
  in call from escript:interpret/4 (escript.erl, line 789)
  in call from escript:start/1 (escript.erl, line 277)
  in call from init:start_em/1 
  in call from init:do_boot/3 
```

Expected results:


```
~ » rebar --version
rebar 2.6.4 undefined undefined undefined
```

Additional info:
Most likely due to both rebar2 and rebar3 erlang applications using the same name (`rebar`).

This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to '31'.

Comment 2 Randy Barlow 2019-09-03 20:03:49 UTC
I've observed that rebar 2 does not work even when rebar3 is not installed:
