I am a beginner trying to setup a developer environment on my new Mac following the steps from this link: http://vanderveer.be/setting-up-my-perfect-developer-environment-on-osx-10-8-mountain-lion-10-8-2-final-edition/.
After executing the files from git, my terminal window now shows:
rbenv: version `1.9.3-p194' not installed
-bash: __git_ps1: command not found
The first line only shows when I open a new terminal window, while the second shows everytime I press return no matter what I type into the terminal.
I have read through many questions on stackoverflow and tried to mimic their solutions to no avail. I think I've made a mistake in installing the package from git as I am not so experienced and I think now I may have messed up the configurations, and was also wondering if there is any way to go back to default settings for bash?
Many thanks!

If you've not installed a newer version of Git on your Mac, start by doing that. You can grab the download from here: http://git-scm.com/download
Once it's installed, you should source git-completion.sh and git-prompt.sh from your ~/.profile (or ~/.bashrc, if you have it):
source /usr/local/git/contrib/completion/git-completion.bash
source /usr/local/git/contrib/completion/git-prompt.sh
That should fix the __git_ps1 error.
I'm not a Rubyist, but the rbenv error is coming from the fact that the setup in the dotfiles you are following is trying to set the default Ruby version to "1.9.3-p194". The rbenv tool is there to make a number of different Ruby versions available, but you have to install them first. In your case, I think you need to run this:
rbenv install 1.9.3-p194
After that, the version will be available, and you shouldn't see the warning anymore.

I've been trying to run a program that uses graphics (which I've already posted about here). This post and other posts have led me to the conclusion that I need create a ~/.bashrc and put in it:
alias ocaml="/usr/local/Cellar/ocaml/4.03.0/bin/ocaml”
However, /usr/local/Cellar/ocaml/4.03.0/bin/ocaml is not a valid file in my system. B/c when I ran this in the terminal:
$ cd /usr/local/Cellar/ocaml/4.03.0/bin
-bash: cd: /usr/local/Cellar/ocaml/4.03.0/bin: No such file or directory
But changing the version to 4.04.0 works:
$ cd /usr/local/Cellar/ocaml/4.04.0/bin
But when I ask the terminal what ocaml I'm running:
$ which ocaml
/Users/Username/.opam/4.03.0/bin/ocaml
It says I'm running 4.03.0
And my error message when I try to run an ocaml program using graphics is :
Error: Cannot find file /Users/Username/.opam/4.03.0/lib/ocaml/graphics.cma
So it seems like my terminal is running 4.03.0 but I don't have OCaml 4.03.0 in /usr/local/Cellar/ocaml/4.03.0/bin and instead I have 4.04.0??
That to me seems very strange.
If anyone could please help me out that would be greatly appreciated! I have spent hours trying to figure out how to run graphics on my computer and I have no clue why the solutions posted in previous StackOverflow posts are not helping :(
i don't find it strange.
The alias command works only in your terminal, not for the entire system.
Probably you have "/Users/Username/.opam/4.03.0/bin/ocaml" in your PATH variable.
I suggest to do:
export PATH="/usr/local/Cellar/ocaml/4.04.0/bin:$PATH"
then:
which ocaml
and the path should be the 4.04 version
It looks like that you have multiple installations of OCaml on your machine. Some of them being installed via opam, and others either manually, or via system package management. I would suggest just to ignore the latter and focus on opam.
To use opam, you need to activate your switch. This can be done manually,
eval `opam config env`
(Note the use of backticks)
You can also put it in your profile, so that opam will be activated every time you logged in. You can even ask opam to do it for you:
opam config setup --user
Finally, if you want to run a program, out of your normal terminal environment, and do not want to depend on some pre-setup steps (i.e., on a client's machine), then you can use opam config exec:
opam config exec -- ocaml my-ocaml-script.ml
I upgraded my Mac to the new OSX 10.10.
brew update failed with:
/usr/local/bin/brew: /usr/local/Library/brew.rb: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad interpreter: No such file or directory
/usr/local/bin/brew: line 23: /usr/local/Library/brew.rb: Undefined error: 0
I tried to follow "Getting a "bad interpreter" error when using brew", but I couldn't get it working.
I do not have Ruby in /usr/local/bin or /user/bin, which may be for same reason which ruby returns nothing.
I have Xcode 5.1 with the command line tools installed. Whenever I start terminal I get:
-bash: /etc/profile.d/sm.sh: No such file or directory
-bash: /etc/profile.d/rvm.sh: No such file or directory
Can anyone suggest possible solutions?
First off upgrade Xcode to 6.1 This is the version that works with Yosemite.
After that make sure you RUN Xcode and Agree to the license ( i know it sucks ).
Note: After Updating My "Oh My Zsh" tools and restarting Xcode it installed some command line tools that I'm pretty sure are important.
There are things to note:
Mac OSX does come with a Ruby preinstalled in /bin/ruby. That is Apple's own installation, used for some of their tools, and basically should be ignored. Updating it could break those tools, and worse, deleting it, will break them. Trying to reinstall it is a pain, so it's better to pretend it isn't there.
We generally recommend using either RVM or rbenv to manage/install any other Ruby version. Those tools are well tested and make it easy to switch back and forth between versions.
rbenv is easier to manage but lacks some of the features of RVM.
Closely follow the RVM installation instructions if you go that way; We see a lot of questions on Stack Overflow caused by people who ignore the directions, or who follow directions on a different site besides RVM's home site. (The RVM authors really do know better than anyone else how to make it work.)
Brew can install Ruby, but switching between versions gets stickier.
It sounds like your PATH variable doesn't include /usr/bin, which is odd, because it should. If it did, it should find the default Ruby.
echo $PATH
will display your search path. It's editable and, if
ls /usr/bin/ruby
shows that Ruby does exist in /usr/bin then you should add it back into the path. You can do that by editing ~/.bashrc, but also check ~/.bash_profile to make sure something isn't messing up the path. And, if you don't understand how the path works, take the time to read about it, because a badly set-up PATH variable can slow your use of the command-line, or cause all sorts of weirdness.
By default there is no /usr/local/bin/ruby. It won't exist using RVM or rbenv either, but Homebrew will probably put a symlink; I don't have it supplying my Ruby, so I can't check that.
I installed vim via brew so I could have the latest version (7.4) and get syntax highlighting for Clojure. No big deal. Unfortunately, the brew version of vim seems to be broken on my system. I also aliased the vim command:
brew install vim # Install went successfully
alias vim=/usr/local/Cellar/7.4.052/bin/vim # Shouldn't be any problems here
When I open the brew version of vim, it fails to load any of my plugins (I use spf13) throwing a bunch of "Undefined variable" and "Invalid expression", etc errors for every plugin in my bundle directory; I just hit enter to continue. My .vimrc loads properly. When I open a file, it opens two tabs, both blank. One is a new file, the other is the file I tried to open, except there's nothing in it.
Potentially useful information: echo $VIM returns an empty line, while echo $ZSH returns /User/bsima/.dotfiles as expected.
Here are my dotfiles, but I don't think the problem lies in those configuration files.
Is this a known bug? Or is something wrong with my vim install?
I have no idea what's going on and I really miss my vim :( As good as Textmate is, I can't be without vim forever.
Edit: MacVim, installed via Homebrew, kinda works. It still opens 2 tabs on startup, but it does open files for editing and saves.
I found the problem: it was with my spf13 vim config. The following commands fixed the issue, in addition to double-checking that symlinks such as ~/.vim and ~/.vimrc were correct:
> which vim # This should output /usr/local/bin/vim since I'm using Homebrew
/usr/local/bin/vim
> cd ~/.spf13-vim-3
> ./bootstrap.sh # Basically re-installs spf13
Firstly apologies if this is a really simple question but Git is absolutely brand new to me. Basically I've been dabbling with a bit of iOS development for a little while and now have a project idea that I want to start working on and for the first time I'm planning on putting this into source control.
Now I know Xcode 4 has some Git integration but I've spotted a couple of posts that suggest the integration isn't that great and it's better to do it the command line way.
So, I've been following instructions here http://git-scm.com/book/en/Getting-Started-Installing-Git and I've downloaded version 1.7.10.3 for Mac and ran the install.
However when I run git --version I get version 1.7.4.4 which is the version that was installed with Xcode I assume?
My question is, how do I make use of my new version 1.7.10.3? The plan is to learn to use Git via command tools and set up a central repository on a server I have at home, then have local copies on my laptop.
As I say I'm really new to this, so a quick step by step idiots guide would be helpful. I have searched and tried to find details here and on google but other than the suggestion to use Git outside of Xcode I've not found out exactly how to do it.
Any advice, or links to a decent tutorial that covers this would be very much appreciated.
Update:
I've changed the path to the new path in .bash_profile (/usr/local/git/bin) and now get git version 1.7.7.5 (Apple Git-26). This still appears to be the wrong version (although this could be me being dense). I downloaded the installer for OSX from the above link. Should I be doing something else. I want to play around with the command line tools so I can get a proper understanding
Update 2:
I'm now also trying MacPorts as recommended in the article. This seems to be downloading a lot more than just Git though
Xcode installs git in /Applications/Xcode.app/... but if you run 'Install Command Tools' then git gets installed also in /usr/bin/git. Xcode uses its private version in Xcode.app. If you installed git in /usr/local/git/bin then you need to include that directory in your PATH. You should have a .bashrc file (or equivalent for whatever shell you are using). Add
PATH=/usr/local/git/bin:$PATH # your shell might use different syntax.
to that file 'rc' file.
Also, note that Xcode would allow you to accomplish your goal of setting up a remote at home while maintaining a local copy on your laptop. Go to the Xcode 'organizer' and click 'repositories'. There you will find all your machine's Git repositories. Choose one, select the 'remotes' folder and then '+' to add your home remote. I use Xcode this way.
Credits goes to #GoZoner for the answer. I'm just summing up everything.
Download official git installer from : http://git-scm.com/download/mac
Install and add its directory to your path :
echo "PATH=/usr/local/git/bin:\$PATH" >> ~/.bash_profile
source ~/.bash_profile
The best way is:
step 1:
Install homebrew on your mac this is the official website Homebrew homepage
From a Terminal prompt:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
step 2:
From a terminal prompt
brew install git
On my Mac OSX 10.6 machine, I started to use MacVIM for vim. Then I noticed my terminal version was different to the MacVIM version (MacVIM was 7.3 and my terminal version 7.2)... I thought they used the same vim?
I need 7.3 for some of the features. So I set about wanting to update the terminal version. I basically cloned it using Mercurial (the perferred way according to the official site) and then did the usual to compile it. This did work and I now have 7.3 in my terminal. But, on some commands when exiting, I can this error:
/bin/bash: q: command not found
shell returned 127
Press ENTER or type command to continue
...I've tried my hardest to try and fix this problem, but trying to reinstall MacVIM, deleting the vim in my /usr/local/bin and compiling again and I just can't get rid of this annoying error.
Can anyone possibly help me? Am I doing this all wrong? ...most of the time I will be using MacVIM, but it'd be nice for me to have it in the Terminal - exactly how I'd have it on my Ubuntu servers.
Any help would be fantastic!
:!q is not :q!. This is probably not a bug.
The error message you're seeing is is most likely the result of accidentally typing :!q instead of :q!, which would be user error, not a bug. :!q shells out to run q, and your shell (bash) is not finding such a command and bails with 127. (For comparison, you might try :!true, :!false, :!vim %, to get a feel of this.)
There isn't really a “fix” for this, and ! is really useful for other purposes; maybe with more practice you'll make the typo less often. You could also try using ZQ instead of :q!; this has other disadvantages (a typo ZZ will instead save the file if it's edited, and ZQ specifically is a vim extension), but at least you see this error again.
The upshot here is basically check to make sure you typed in your commands right, I guess.
I'm not sure on the exact path, but somewhere a few folders deep into the Applications/MacVim.app folder is the vim executable that will also run in a terminal (Use the -g option to launch it in GUI mode).
You should be able to throw this in your .bashrc:
alias vim=/Applications/MacVim.app/Contents/MacOS/vim
This is the homebrew formula for vim. Try these settings for "configure" or just install homebrew and install vim from there.
system "./configure", "--prefix=#{prefix}",
"--mandir=#{man}",
"--enable-gui=no",
"--without-x",
"--disable-nls",
"--enable-multibyte",
"--with-tlib=ncurses",
"--enable-pythoninterp",
"--enable-rubyinterp",
"--with-features=huge"
system "make"
system "make install"
