Rebar3 Installation Bootstrap Error: escript: exception error: no match of right hand side value {error,enoent}

[sagungargs]

While trying to install rebar3 and using the command ./bootstrap I am getting the above error

[sagungargs]

@tsloughter @ferd any inputs or links where I can resolve this. I am getting this only on my Macbook Air, my colleague could smoothely install the same a few days back on OSX machines. Since this is an installation issue that I am facing with rebar3 I am getting a little impatient. After enjoying your talk at EUC SF 2015 I can't wait to get my hands on it for my project

[ferd]

Yeah sorry I was out for the week-end. If the impatience is too much, you can always use one of our nightly-built versions at http://www.rebar3.org (direct link: https://s3.amazonaws.com/rebar3/rebar3).

In any case, do you get any output? This error ({error, enoent}) tends to happen after an unsuccessful bootstrap command because something else failed to compile.

Without any of the compile output, it's hard to diagnose anything.

[tsloughter]

@sagungargs is this with the latest master? It should give more output than that. Also run with DEBUG=1 ./bootstrap and let us know what OTP version you are running.

[sagungargs]

@tsloughter & @ferd thanks for the inputs tried figuring out the OTP version; both OTP_RELEASE and OTP_VERSION are missing from the installation at erlang installation folder

$ cat releases/17/OTP_RELEASE 
17.3

, apologies for not reporting the version anything beyond 17. I took a cue and installed the latest version OTP 17.5 (Standard Edition from Erlang Solutions Download section for Mac OSX Yosemite (10.10.1) and tried bootstrapping again with ./bootstrap, this time I move beyond the previous error {error,enoent} so I really don't know why did this occur in the first place.

Now I am getting

===> Bad packages index, try to fix with `rebar3 update` 

just after running the ./bootstrap command though all looks fine at the end of the script. I tried rebar3 update command and it reports

rebar3: command not found

I copied rebar3 in the msgpack-rpc and tried using it. On ./rebar3 compile it throws the same

===> Bad packages index, try to fix with `rebar3 update` 

error and goes on to compile the 3 applications ranch, msgpack and msgpack-rpc

Has rebar3 installed correctly and is this an expected behaviour? for the error it throws? Because I was not getting these errors in other two Mac OS X machines

[ferd]

I guess the problem would be with that missing OTP version file: https://github.com/rebar/rebar3/blob/578a27f506a00615f41803c277cc3069a7f3022a/bootstrap#L192-L220 and https://github.com/rebar/rebar3/blob/0537a0699d01e4ae61dd32db0d964224bf9a1f5e/src/rebar_utils.erl#L294-L301

This file is specified to be required in http://www.erlang.org/doc/system_principles/versions.html#id65106 -- I do believe however, that releases generated with Reltool (and maybe systools?) don't include them, which would be a bug. Then when the Erlang Solutions folks generate their custom releases and packages, the file turns out to be missing.

I guess the required workaround will be to behave such that when the file isn't there, we display a warning ("OTP_VERSION file missing from the Erlang/OTP install; assuming major version ~p") and use only the major version.

Otherwise we'll need to keep failing the way we are until toolchains are fixed.

---

For the current problem, I'd really like to see logs about the whole failing run, not just the failing message to be able to properly locate things.

---

For the msgpack rebar3, you can just use the one I linked to previously that is a nightly build. It should work fine. The bad package index might be there from a previous run or just has never run at this point in time. rebar3 update should fetch a hex index and save it to disk, hopefully fixing the problem and then you'd have a usable version.

But it's possible that if you use conflicting rebar3 versions, both could be using a distinct package manager version and they'll keep breaking eachother.

[tsloughter]

So the "error" about packages is harmless (unless you try to use a package dependency.

But I see that we can move the loading of the package index to somewhere that it won't happen unless you do have a package dep listed so that it won't show that message if you don't.

Updating now.

[sagungargs]

rebar3 update

still throws

-bash: rebar3: command not found

[ferd]

yes that's because the command is not in your path. Is the rebar3 file even on disk?

[tsloughter]

@sagungargs can we close this?

this is the whole thing output im getting

[ferd]

You are running a version of Erlang that does not have the crypto NIFs compiled in. You need to build (or install) a copy of Erlang with these libraries for things to work.

[benseshi]

how to do that sir can you help me with this

[benseshi]

can you brief me step by step

[ferd]

Aside from what is documented at http://www.rebar3.org/docs/getting-started#section-installing-erlang I do not really have the details nor the information required about your system to give any help here.
