RVM fails installing Ruby

问题

I'm trying to install an older Ruby version via RVM but the installation fails with an error I've never seen before. I've already changed the rvm_max_time_flag but it didn't help. What can I do here?

rvm install 1.9.3p484

No fallback URL could be found, try increasing timeout with:

    echo "export rvm_max_time_flag=20" >> ~/.rvmrc

There has been an error fetching the ruby interpreter. Halting the installation.

回答1:

It says that the URL does not exist OR the URL has no ruby version available for download.

Try installing with a compatible ruby-gem version:

rvm install 1.9.3p484 --rubygems 2.0.9

OR

Update

Are you sure that you are using an updated version of RVM?

rvm get head
rvm install 1.9.3

Hope it helps :)

回答2:

1) Make sure you are using latest RVM rvm get head 2) and then install new ruby rvm install ruby-2.3

Solution

Do rvm list known. If it does not list the ruby version one is after, one can still install that version from local source. Some ruby versions are not maintained and won't be listed and rvm might generate the wrong URL.

For example installing ruby-1.9.3-p484 goes like this:

First download the ruby archive into RVMs archives folder:

cd ~/.rvm/archives; wget http://cache.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p484.tar.bz2

Then install with the following flags:

rvm install 1.9.3-p484 --verify-downloads 2 --disable-binary

Explanation

I had to do it like this after not being able to do: rvm install ruby-1.9.3p484

Since the above command generated this error:

The requested url does not exist(22): 'https://cache.ruby-lang.org/pub/ruby/./ruby-1.9.3p484.tar.bz2' Checking fallback: https://ftp.ruby-lang.org/pub/ruby/./ruby-1.9.3p484.tar.bz2 No fallback URL could be found, try increasing timeout with:

echo "export rvm_max_time_flag=20" >> ~/.rvmrc

There has been an error fetching the ruby interpreter. Halting the installation.

I resolve that just changing the mod of the path of rvm

sudo chmod 777 -R /path/to/rvm 

in my case: /usr/local/rvm
