While installing the ruby 2.6.6 I'm getting this error:
Error running '__rvm_make -10'
please read /home/.rvm/log/1642694273_ruby-2.6.6/make.log
There has been an error while running make. Halting the installation.
I've tried to reinstall rvm but this changes nothing.
Other ruby versions are installed just fine.
rvm install 2.6.6 --with-out-ext=fiddle worked for me
