rvm

After update to Mountain Lion, I tried install 1.8.7, and I got error. X11 file not found, I installed Xquarkz, but nothing changed. Whats wrong? Fail to find [tclConfig.sh, tkConfig.sh] Use MacOS X Frameworks. Find Tcl/Tk libraries. Make tcltklib.so which is required by Ruby/Tk. clang -I. -I../.. -I../../. -I../.././ext/tk -DHAVE_RB_SAFE_LEVEL -DHAVE_RB_HASH_LOOKUP -DHAVE_RB_PROC_NEW -DHAVE_RB_OBJ_TAINT -DHAVE_ST_PTR -DHAVE_ST_LEN -DRUBY_VERSION=\"1.8.7\" -DRUBY_RELEASE_DATE=\"2012-06-29\" -D_XOPEN_SOURCE -D_DARWIN_C_SOURCE -DWITH_TCL_ENABLE_THREAD=0 -fno-common -g -O2 -fno-common -pipe -fno

I am not able to switch the current Ruby version: ➜ ~ rvm list rvm rubies ruby-1.9.2-p290 [ x86_64 ] ruby-1.9.3-p0 [ x86_64 ] ➜ ~ rvm use ruby-1.9.3-p0 RVM is not a function, selecting rubies with 'rvm use ...' will not work. donald Fixed it. I needed to add: [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This loads RVM to .zshrc The Mitra Boy This happened to me too. I had: export PATH=~/.rvm/bin:$PATH Added in my .bashrc. All I had to do was add another [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" to the same file and it worked! Of course, you have to

So I'm trying to get thin to run as a service with RVM. After a thin install I manually updated /etc/init.d/thin to use an su - user when running the config command so that thin was running as a local user, rather than root. So far so good. Now, when I try to sudo service thin start it looks like it's trying to use the non-RVM version of Ruby (1.8.7 which was installed on the box to start with) to actually execute the command. I did a gem install thin on the non-RVM version, which then gets me a uninitialized constant Bundler message—Bundler is only installed in the RVM gems, not the system

Above doesn't work first time, works 2nd time. Try to set ruby version to 2.0.0 for any new shell windows. Doing $ rvm use 2.0.0 --default gives Warning! PATH is not properly set up, '/home/durrantm/.rvm/gems/ruby-1.9.3-p125/ bin' is not at first place, usually this is caused by shell initialization files - check them for ' PATH=...' entries, it might also help to re-add RVM to your dotfiles: 'rvm get stable --au to-dotfiles', to fix temporarily in this shell session run: 'rvm use ruby-1.9.3-p125' . Using /home/durrantm/.rvm/gems/ruby-2.0.0-p247 Then doing the same $ rvm use 2.0.0 --default

Q: Do we have anything functionally equivalent in Python to the Ruby version manager 'rvm' ? ( RVM lets you easily switch completely between different versions of the ruby interpreter and different sets of gems (modules). Everything concerning download-build-install-switch of interpreter(-s) and gems gets taken care of by invoking rvm. It is all run under your regular user account.) Yes, it is virtualenv along with virtualenvwrapper . update: you may install both at once with virtualenv burrito . Update : the correct answer is now probably pyenv . For scientific computing, the corresponding
