error while fetching bbmustache

[benoitc]

I was trying to build from scratch rebar3 and got the following issue:

[rebar3] ./bootstrap                                                                                         16:13:40  ☁  feature/certifi ☀

Is this with your changes in the PR? I'm seeing in Travis that for 17.5 and 18 your PR is failing to fetch bbmustache as well... Very weird.

[benoitc]

yes it's my change. I didn't try without it though...

[tsloughter]

@benoitc so this is due to your change? Are you working on the PR to fix it?

[benoitc]

@tsloughter just retested. So yes it comes from my branch. The error happen because it tries to use `certifi:cacerts()ù before it has been compiled when running the update step. Full trace is:

Ah! So you added it to bootstrap now I see. Great, I'll close this issue and get the PR merged then!

I have excatly the same error while building rebar3 on the raspberrypi

Same on clean Ubuntu 14.04.2 TLS with esl-erlang. A different reason in debug though:
