On Mac Sierra Beta, rbenv install 2.4.0 hangs at "use readline from homebrew"

ruby-build: use readline from homebrew

... at which point I hang

I googled like crazy, reinstalled new brew versions of readline, openssl libyaml and libffi. Any ideas?

[small-fish]

I had the same problem. It was resolved by reinstalling rbenv

[lowderdev]

Also having this problem. Reinstalling rbenv did not fix it for me.
Tried reinstalling lots of stuff, and ran brew update && brew doctor.

[small-fish]

If you used to use rvm, make sure that you removed it completely.

[ahalls]

Patience

[lowderdev]

This fixed it for me:

RUBY_CONFIGURE_OPTS=--with-readline-dir="$(brew --prefix readline)" rbenv install 2.4.0

[markhughes]

@lowderdev You have made my day, hour wasted - IOU a beer!

[ricardomeza]

This works for me too, tks @lowderl !

[mislav]

Thanks for sharing the workaround, @lowderl.

It's strange that this step should fix the installation because --with-readline-dir="$(brew --prefix readline)" is basically identical to what the "use readline from homebrew" step does.

I don't run macOS beta so I can't look into this yet, but if anyone is willing to look more closely into this, I would be grateful. Two things could be of use:

• Tailing the log at the time of the process being stuck: tail -f "$(ls -t $TMPDIR/ruby-build.*.log | head -1)" in another tab;
• Enabling bash verbose mode by adding set -x to the beginning of ruby-build executable.

[paniclater]

I thought I was having this problem, but I tailed the logs and cannot reproduce the issue. I think that it just takes a long time to install and without the output feedback I was assuming it was hanging.

[ghost]

@paniclater I encountered the same thing. Without feedback, it does appear to hang, but after about 3-4 minutes, the install completes successfully.

[skirdey]

Had to wait a few minutes, it worked.

[murnun]

Same. Just had to give it few more mins...

[mgadda]

While we're collecting data: I gave it several hours. It did not work.

[billfienberg]

It took several minutes for me, but it did eventually succeed.

[orospakr]

To get better visibility on what's going on in the build process, I recommend running builds with -v. ie.: rbenv install -v 2.4.21

[davidcpell]

OSX 10.12.6

I'm having this problem and have let installations go for ~1 hour without success. So far I've tried uninstalling/reinstalling rbenv a couple times (using homebrew and git clone). When I use top and pstree to inspect processes it says that they are "sleeping":

Still having this problem, though it seems to happen regardless of whether readline is installed via homebrew (in this case I had re-installed homebrew and not installed readline). The processes are all just sleeping indefinitely until I send the kill signal. @mislav Here are the logs:

BUILD FAILED (OS X 10.13.3 using ruby-build 20171226)

I met the same situation. It hanged there for a few minutes, but did complete.

@lowderl 's workaround worked for me when nothing else did.
RUBY_CONFIGURE_OPTS=--with-readline-dir="$(brew --prefix readline)" rbenv install 2.4.2
Approx. 10 mins for me on a 2010 MBP running Sierra.

[njm2112]

My install seems to be failing at the creating: ./config.status step:

configure: ruby library version = 2.5.0
configure: creating ./config.status
sed: 1: "s/.*%!_!# !%!_!#  _%!_! ...": unterminated substitute pattern
configure: error: could not make ./config.status
make: *** No targets specified and no makefile found.  Stop.

Any advice for a workaround would be appreciated!

Same issue trying to install version 2.5.1

$ rbenv install 2.5.1

adding -v to the command like so rbenv install -v 2.5.1 has no effect on the command line output

@lowderl thanks! it's worked...

Closing since most people have reported that the build process is in fact just taking a longer time, but not completely hanging.

Please reopen and provide extra info if you're experiencing hanged builds for newer versions of Ruby + newer macOS.

In my case it helped to deactivate the antivirus software Avira.

[cpg94]

Took a few minutes for me, patience everyone.

Indeed, that's what it was for me, too. Might be a UI enhancement to include some kind of progress indicator, determinate or indeterminate, just to provide transparency and alleviate these issues.

[cnees]

How much patience?

For me, 6 minutes. Hope that helps!

[roeniss]

After 5 minutes and it finished. Unbelievable, actually.

[zashraf1985]

adding -v helped rule out the hanging problem.

[twome]

@mislav please change the default behaviour to verbose mode, or fix the existing UI! No program should ever do anything that takes several seconds, let alone minutes, without telling the user why they have to wait and and trying to approximate the time remaining! In this thread alone, hundreds of probably very reasonable and smart people have been confused by this.
