I'm very inexperienced, and was following directions here ---
Installing ifuse with Homebrew results in ERROR message
I believe I made some unintended changes when I was editing the file in
$ vi `brew formula ifuse`
without understanding what I was doing. When I went to install ifuse, it just give me an error. Is there any way to get back to the original file/undo my edits?
Homebrew formulas are in a local git repository. You can restore the original formula by typing:
cd `brew --prefix`/Library/Taps/homebrew/homebrew-core/Formula
git checkout ifuse.rb
I have tapped something as a certain name, but now I want to change the name. How do I do that in homebrew?
Today:
$ brew tap
[...]
existing/tap-name
Desired:
$ brew tap
[...]
new/tap-name
Homebrew doesn't (AFAICT) store information about what taps are installed anywhere on the filesystem, so all you need to do is move the directory to the correct new location.
This is made easier as brew --repo my-tap/name will tell you where a tap should go even if the tap doesn't yet exist.
old_tap=existing/tap-name # What you currently see in `brew tap`.
new_tap=new/tap-name # What you want to see in `brew tap`.
old_path=$(brew --repo "${old_tap?}")
new_path="$(brew --repo "${new_tap?}")"
mkdir -p "$(dirname "${new_path?}")"
mv "${old_path?}" "${new_path?}"
I have installed 1.6.0_beta3 since my company's app depends on Xcode 8.
When running the bootstrap script as explained I need to enter my github username.
Why? It's a public repository. Nothing happens when I enter my github username.

I also tried with:

Seems like more things were broken after updating OSX. Thanks Appium.

The official install instructions say:
If you want to build the wx application, you will need to get
wxWidgets-3.0 (wxWidgets-3.0.0.tar.bz2 from
http://sourceforge.net/projects/wxwindows/files/3.0.0/) or get it from
github with bug fixes:
$ git clone --branch WX_3_0_branch git#github.com:wxWidgets/wxWidgets.git
Who wouldn't want bug fixes:
$ git clone --branch WX_3_0_branch git#github.com:wxWidgets/wxWidgets.git
Cloning into 'wxWidgets'...
fatal: Remote branch WX_3_0_branch not found in upstream origin
Does anyone know where the bug fix version is located?
Response to comment:
With all caps, I get:
$ git clone --branch WX_3_0_BRANCH git#github.com:wxWidgets/wxWidgets.git
Cloning into 'wxWidgets'...
ssh_exchange_identification: read: Connection reset by peer
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
For future searchers: in order to use github commands like above, you need to setup ssh keys for your computer. I had already done that, but for some reason it didn't work a few hours later. Firewall problems at my new location? I don't know. I moved to a different location/server from where I was getting the Connection reset by peer error, and then I created a new ssh key, and I was able to download and install wxWidgets. The git clone command just downloads the source, so you probably want to be at the ~/Downloads prompt when you issue that command. The Erlang install directions tell you how to install wxWidgets.
The branch in question is named WX_3_0_BRANCH — all uppercase.

Updating e088818..5909e2c
Error: Failed while executing git pull origin refs/heads/master:refs/remotes/origin/master
I found a blog post by someone who experienced a similar problem after having installed Mountain Lion (which I did this week too). He explains how he removed the files referred to in the error message
I removed these files:
$ cd $(brew --prefix)
$ rm cocot.rb
However, removing these files didn't help with the brew update. Instead I had to manually update brew through git:
$ cd $(brew --prefix)
$ git fetch origin
$ git reset --hard origin/master
$ brew update
Already up-to-date.
Assuming those instructions are correct (which I maybe shouldn't assume), I tried to follow these instructions and do
$ cd $(brew --prefix)
$ rm cocot.rb
However, it said 'file doesn't exist' when I tried to rm cocot.rb
One thing I'm not sure about is the cd $(brew --prefix) Are those the exact words I type or do I have to replace prefix with something? the cd was successful, so I'm assuming it was correct -- it moved me into /usr/local, but there was no file to remove. Contents of /usr/local are
Cellar clamXav git mysql var Library doc heroku mysql-5.5.15-osx10.6-x86_64 README.md etc include rvm bin foreman lib share
At any rate, do you know how I can fix the 'brew update'
Update: After removing the files according to favoretti's instructions and trying chown -R <your_username> $(brew --prefix)/.git, I got the following error running brew update

Error: Failed while executing git pull origin refs/heads/master:refs/remotes/origin/master
You need to do the following:
cd $(brew --prefix)
rm Library/Formula/argp-standalone.rb
rm Library/Formula/cocot.rb
And then do the
git fetch origin
git reset --hard origin/master
brew update
Basically, to explain a bit more:
cd $(brew --prefix)
tells cd to change the directory to whatever brew --prefix will output.
If you try executing brew --prefix command you should see something in lines of:
brew --prefix
/usr/local
So the command would be in this case an equivalent of cd /usr/local.
Newer brew versions have formulae under its installation prefix and Library/Formula/, so that's where you need to look for those outdated/changed files.
Note, that if you changed those formulae yourself for a particular reason (like pinning a version) this action will revert them back to default ones and may produce unwanted effects.
#TedPennings noted in comments that this worked for him, but his sequence was:
chown everything to my_username:admin, ie, sudo chown -R ted:admin $(brew --prefix)
run the two git commands above,git fetch origin and git reset --hard origin/master
cd $(brew --prefix)
git reset --hard HEAD
brew update
This is caused by an old bug in the update code that has long since been fixed. However, the nature of the bug requires that you do the following:
cd $(brew --repository)
git reset --hard FETCH_HEAD
If brew doctor still complains about uncommitted modifications, also run this command:
cd $(brew --repository)
git clean -fd
$ cd $(brew --prefix)
$ git clean -fd
$ git reset --hard
$ sudo chown -R `whoami` `brew --prefix`
$ brew update
Note: steps 2&3 worked for me since I did step 5 before 4 before I got the error. The brew update before changing the owner of the folder caused the whole problem.
I had a similar issue where my brew package library got downloaded as a root user and then I was not able to run brew update as git would complain about not able to merge the file.
Solution was to do :-
sudo chown -R <user> /usr/local/Library
Resetting the brew repository should be the most efficient way if you don't mind to discard potential modifications on formulas you might have been applied:
$ cd `brew --prefix`
$ git fetch origin
$ git reset --hard origin/master
$ brew cleanup --force
$ brew update
I was able to fix this on my machine by adding admin group write (and setgid bit) permission at these paths:
sudo chmod -R g+ws /usr/local /Library/Caches/Homebrew
The s sets the group id on execution so that the write permissions aren't lost the next time a different admin user updates or upgrades Homebrew.
This answer is somewhat incomplete because when I try to do brew cleanup --force there is a permissions issue when Homebrew tries to remove content in /usr/local/Cellar/. (Unfortunately I'm not able to investigate this further at the moment.)
Another option is to just use git stash.
The brew update command performs a git pull, so if there are any changed files (or even file attributes, which happened to me when I changed permissions in the directory recursively) you have to somehow fix the conflicts. Using git stash is one way; it takes any changes and puts them aside so you effectively revert to the last updated repo version. The Homebrew 'location' is by default /usr/local and it installs as a git repository. You can look for a .git folder to see for yourself. I'm writing a homebrew uninstall script to be posted on my GitHub profile soon with more info.
sudo chown -R USER /usr/local/bin
note - for USER use command whom i.e. your username
sudo brew doctor
This approach may be simpler than some. It involves:
fixing a git issue so you can delegate management of changes to it again.
no manual moves of files or directories.
no manual adjustments of file or directory permissions.
Steps (with notes for those who want explanations):
cd $(brew --repository) // see Note 1 below
git remote add brew https://github.com/Homebrew/brew // see Note 2 below
git pull brew master // promising fast-forward report!
brew update // see Note 3 below
Overview:
From what I can tell, the actual cause of this issue is a change in the repo url. It's now brew and was brew.git. (Full up-to-date url: https://github.com/Homebrew/brew)
Note 1: This first command takes you from anywhere in your file structure to the correct directory. The directory structure is different for me than what others show above (Mac OS 10.11.16), but with this command, those differences should not matter.
Note 2: This second command adds the correct remote url to a new alias; I did so just in case this approach didn't accomplish what I wanted and I needed the previous address again. Since the new remote worked, I'll invite someone else to comment on simply changing the url aliased by origin. I'll happily update the answer to reflect what worked for you.
Note 3: This forth command has exactly the desired result: it reports a large number of updates, including the particularly nice report of "==> Migrated HOMEBREW_REPOSITORY to /usr/local/Homebrew!" (emphasis theirs).
This post helped me after updating to El Capitan. In my case, chown wasn't working ("zsh: command not found: chown"), so step 1 was adding this line to my .zshrc:
export PATH="$PATH:/usr/sbin"
I'd already tried several of the more popular answers above, so I'm pretty sure that git status was coming up clean by the time I pasted in the critical command from the blog post:
sudo chown $(whoami):admin /usr/local && sudo chown -R $(whoami):admin /usr/local
This should work.
1. cd `brew --prefix`
2. git fetch origin
3. git reset --hard origin/master
4. sudo brew update
