Installing rvm with ruby on a Raspberry Pi takes a long time

[dahofer]

Hello,

This is on a Raspberry Pi model B+. I ran the following command to install:

curl -L https://get.rvm.io | bash -s stable --ruby

It took 1-2 hours (not sure exactly how long because I left the room for a while). Most of the time was taken up by compiling ruby 2.1.5. I then complained about this on twitter and got this response (impressive!): https://twitter.com/rvm_io/status/534119299301257216

So having binaries for the ARM 7 would be great. If I can do anything to help, let me know.

Raspberry Pi A, B and B+ have ARM 6, not 7. Raspberry Pi 2 has ARM 7. If you have one set of binaries it should be for ARM 6. If you can have two sets of binaries, then make separate ARM 6 and 7 builds - it will make Ruby faster on the Pi 2.

I built an image for Raspberry Pi 2. We'll have to change something in the installer ... @mpapis already pointed me to place where it should be changed.
Meanwhile you can install on Raspi 2's using

rvm mount -r https://rvm.io/binaries/experimental/armv7l-linux-eabihf/ruby-2.2.1.tar.bz2

in 2 mins 30 secs. ;-)

Cool! I will try that out when I get a chance.

@haslinger Seems nice, but checksum is not matching. Is it expected behaviour?

Downloaded archive checksum did not match, archive was removed!

@roolo definitely not, I will look into this, thanks for pointing it out to me.

what is the current state of play with this now? ruby 2.1.5p273 (2014-11-13) [arm-linux-gnueabihf] is installed by default onto latest Jessie distribution for Raspberry Pi. Is it possible to use this so that a long compile from source is not necessary?

RE #3145 (comment) :

I don't currently have my RPi. I hope I'll be able to check it next week.

If there is 2.1 Ruby package, then it could be possible workaround, but it doesn't seems like optimal solution bypass RVM when actually want to use it ;)

Anyway if somebody just want SOME ruby, package could be a way.

Bump :)
