I recently formatted my Mac OS X Mountain Lion and I installed pypy using brew -v install pypy as always. However, this time, when I hit pypy in the terminal, bash reported command not found.
I went check and brew did install pypy in the normal directory /usr/local/Cellar, but there is no link to pypy in /usr/local/bin as it used to have.
I made an alias with my mouse and moved it to /usr/local/bin. Then I typed:
chmod 755 pypy
And I tried to run pypy again typing:
pypy
so...
-bash: /usr/local/bin/pypy: cannot execute binary file
Does anybody have any idea of what is happening?
Try removing the alias you created with the mouse and create one with :
sudo ln -s /usr/local/Cellar/pypy /usr/local/bin/pypy

I'm on the M1 MacBook.
This is the error when I try to install Homebrew:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Homebrew is not (yet) supported on ARM processors!
Rerun the Homebrew installer under Rosetta 2.
If you really know what you are doing and are prepared for a very broken experience you can use another installation option for installing on ARM:
https://docs.brew.sh/Installation
So how do I "Rerun the Homebrew installer under Rosetta 2."?
Got an answer from a developer in the Homebrew github https://github.com/Homebrew/brew/issues/9173
arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Use this to install packages:
arch -x86_64 brew install <package>
If you have not yet installed Rosetta 2 to emulate Intel CPUs on ARM Macs, you will get the error arch: posix_spawnp: /bin/bash: Bad CPU type in executable. Prompt a Rosetta 2 installation with:
softwareupdate --install-rosetta
I have two instances of brew installed, the Intel version that runs using Rosetta2 and which installs to /usr/local/bin and the Arm version that runs natively and installs to /opt/homebrew/bin. Now it is all working, I do not have to start iTerm using Rosetta.
I have these aliases to reach the two versions.
ibrew='arch -x86_64 /usr/local/bin/brew'
mbrew='arch -arm64e /opt/homebrew/bin/brew'
I have the native version in my path first:
path=( /opt/homebrew/bin /opt/homebrew/opt /usr/local/bin /usr/bin /bin /usr/sbin /sbin /Library/Apple/usr/bin )
Now I can try mbrew search and mbrew install. If they work, I am good to go with a native program. For example:
mbrew install ag
If brew fails I try building from source, with verbose output, e.g.
mbrew install -sv rust
Be warned, this takes a while and may still fail.
If it still fails, (and mbrew install -sv go results in a segmentation fault for me) I have two choices. Use ibrew search and ibrew install to get the Intel build instead, or examine the verbose output and look for problem dependencies. In some cases an install -s on the dependencies is enough to get the native brew to work.
I must stress that native brew always prints this warning
Warning: You are running macOS on a arm64 CPU architecture.
We do not provide support for this (yet).
Reinstall Homebrew under Rosetta 2 until we support it.
So proceed at your own discretion.
For completeness, and assuming you have iTerm2, Rosetta2 and the Xcode command line tools installed, I did this to install brew under Rosetta (with credit to all those who have posted on this page before me):
Copy the installed iTerm2.app application to iRosetta2.app
Press command+I to Get Info for iRosetta.app, click Open Using Rosetta2
Run iRosetta2 and use this command from https://brew.sh
Like so
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)
alias ibrew='arch -x86_64 /usr/local/bin/brew' # put this in ~/.zshrc
And I did this to install native brew, taken from other contributors to Stack Overflow and the Homebrew alternative installation site, using iTerm2 without Open Using Rosetta2
mkdir ~/homebrew
curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew
sudo mv ~/sudo mv homebrew /opt
mbrew='arch -arm64e /opt/homebrew/bin/brew' # for .zshrc
export PATH="/opt/homebrew/bin:/opt/homebrew/opt:$PATH" # also for .zshrc
Edit
Time has passed and I have changed the architecture to arm64e following Fernando García Redondo observation. Now the warning about Arm architecture not supported has gone and Rust and Go install without problems and without compiling from source. I assume the good people at Homebrew have been working hard over Christmas. Thanks!
Edit Feb 21
The Homebrew team have announced that they support Apple silicon. So I wondered if I could delete my aliases and just use brew to install for Apple silicon. The short answer is no! if you run brew from /usr/local without the arch -x86_64, it complains that /usr/local is reserved as the Intel default prefix and using /opt/homebrew is required. So I will retain my two aliases and try mbrew first and only use ibrew if the native brew fails.
Another option is by going into your applications in Finder, select Terminal and press ⌘+I and check the "Open using Rosetta" option.
Sorry if the formatting is off, first time posting a solution.
The easiest way to run Homebrew is with Rosetta 2.
1. Duplicate Your Favourite Terminal for Rosetta
Find your favourite terminal, right-click to duplicate it, and rename it for easier identification. In this example, I'm using the default Terminal app on Big Sur 11.2.1.
Right-click the Terminal Rosetta and go to Get Info to check the Open using Rosetta option.
2. Install Homebrew
Open the rosetta terminal and run the following command:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Running this command will ask you for the password, and then it will provide you with the information of what all it will install and which new directories it will create.
3. Using Homebrew
Once HomeBrew is installed, you can start using it to install your required packages into the M1 Mac.
Run the following command to get brew help:
brew help
To install a package, you can run the following command:
brew install packagename
That’s all about installing and getting started with Homebrew on Apple M1 Macs.
EDIT: Thanks all! Upvote to help other devs! Homebrew 3.0.0 now officially supports Apple Silicon (https://brew.sh/2021/02/05/homebrew-3.0.0/)
After I installed Rosetta, I added an alias so I can use brew install <package> as I would normally.
alias brew='arch -x86_64 brew'
I agree with everyone else in that you need to add the arch -x86_64 in front of the original command so thought to include that alias to help anyone finding this thread in the future
arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)" worked on my new M1 Mac
Do below
/usr/sbin/softwareupdate --install-rosetta --agree-to-license
arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
alias brew='arch -x86_64 brew'
brew install azure-cli
now try az login. you are good to go
You can change the setting of Terminal to launch it using Rosetta.
Go to your Application/Utilities folder, right click on the Terminal App and check the tick box 'Open using Rosetta'
But to be honest, I have Homebrew installed without Rosetta. Just removed the x86 version yesterday and installed a fresh version without Rosetta.
I tried to install homebrew onto my mac, but I couldn't because curl wasn't found. I typed:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
This returned this error:
-bash: curl: command not found
So, I tried to install curl but apparently to install curl, I need to use curl? This is what I found:
Run in Terminal app:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" <
/dev/null 2> /dev/null
Run:
brew install curl
Done! You can now use curl.
However, this uses curl to install curl, so it gives the same error message: -bash: curl: command not found
TL;DR, how do I install curl on mac without using curl
I solved the problem!
To use bash on mac:
Go to terminal ––> preferences
Click on Shells open with: and set it to Command (complete path)
Enter one of the following:
/bin/bash
/bin/csh
/bin/zsh
/bin/zsh-4.0.4 (Mac OS X 10.2.8 or earlier)
/bin/zsh-4.1.1 (Mac OS X 10.3 or later)
/bin/ksh (Mac OS X 10.4 or later)
/bin/ksh worked for me

I thought I broke my curl symlink somehow too, and somewhere in there I ran into your same issue, where no command would work. Somewhere in this mess, I fixed it.
https://brew.sh/
The main website requires you to install wget, maybe it gets deleted when you uninstall homebrew.
Regardless I found a way to install it using Ubuntu commands.
https://xmrig.com/docs/miner/build/ubuntu
but ran into an issue where I had to download cmake from the developer website and add it to the path in it's menu options on Mac OS X 10.11 to compile and run my program as ./program instead of program, then I installed macports(opened a new terminal window), and installed hwloc with macports, to no avail, just getting totally different errors.
I've also tried to add curl as an alias of curl into the bash profile and it recognized the error after I used this;
https://github.com/Homebrew/homebrew-core/issues/5084
However, I forgot I have an identical computer that is working just fine, but when I run "which curl", in the working computer, I get /usr/bin/curl, instead of /usr/local/bin/curl, so I ran
export PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/bin/curl"
I'm still getting the error, so I used vim, to sudo edit the /etc/paths file by using
sudo vim /etc/paths
i for edit
esc to exit edit mode
:x to save
Restart Terminal
Still getting a 403 SNI Error cannot download Python 3.9
rm -rf /opt/local/bin/curl
rm -rf /usr/local/bin/curl
which curl finally returns the correct path, /usr/bin/curl
exit
Restart Terminal
Still same error so I removed /usr/bin/curl from /etc/paths, and export file. Also deleted the bash profile, as the working computer doesn't return one, and...still the same error, so I conclude that "curl is not in path" should be ignored.
I did get brew doctor to return with no errors.
brew upgrade curl
curl not installed
brew install curl
403 Error SNI is required.
brew upgrade openssl
openssl 1.1.1j already installed
In my case, I made a mistake while editing my $PATH.
I would recommend looking at all your ~/.bash_profile and ~/.zshrc.
Remove ALL code related to $PATH. Carefully add things back in.
I am trying to install ROOT (cern.root.ch). When I run ./configure , I get a message that libX11 is missing and must be installed.
I did some research and found that I need to install
) XQuartz (I already have the latest version.)
) Command line tools in Xcode.
I tried installing Command Line Tools from apple's developer website. The installation goes through smoothly but how do I know whether it has been installed? I still get libX11 missing error with root's configure command.
I also tried xcode-select --install and it once went through smoothly and then later again gives error saying this package is no longer maintained - or something of that sort.
I understand I may have multiple installations... But I am still facing the problem of not having libX11 and not being able to install ROOT.
Thanks,
Hershal.
This link and the one referenced in it suggests you use homebrew (brew) to install it
$ ruby <(curl -fsS https://raw.github.com/mxcl/homebrew/go)
$ brew doctor
Remember to add the Homebrew directory to your PATH by adding the directory (found with brew --prefix) to your .bashrc, .zshrc or whatever shell file you’re using (.bashrc is the OS X default). We’ll also add the XQuartz binaries to the PATH in case anything needs them in the future.
export PATH=/usr/local/bin:/opt/X11/bin:$PATH
Start a new Terminal session to pick up the changes.
Now that Homebrew is installed, we can use it to install the required dependencies. Each may take some time as Homebrew generally compiles from source.
$ brew install gfortran # Fortran compiler
$ brew install python # Python interpreter
$ brew install pcre # Regular Expressions library
$ brew install fftw # Fast Fourier Transforms
$ brew install cmake # Cross-platform make
install root
$ brew tap homebrew/science
$ brew install --with-cocoa root
You don't say whether you have installed XCode as well as the commandline tools but I think you will need it
I spent quite some time figuring out how to install libSVM on Mac OSX and use easy.py and grid.py. I've done quite some research but there are problems such as gnuplot isn't installed in the place where easy.py is calling it with brew.
It turned out I have to do the following steps
go to https://www.dropbox.com/s/rpn6yersv06tttz/gnuplot-4.2.5-i386.dmg
download the gnuplot-4.2.5-i386.dmg
open the resulting DMG file
open the gnuplot-4.2.3 DMG the Extras folder
drop Gnuplot.app into your applications folder
go to /usr/bin in terminal and do
$ sudo ln -sf "/Applications/Gnuplot.app/Contents/Resources/bin/
gnuplot"
You will be prompted to install X11 if you haven't done so, but after that if you run sample line like
python easy.py svmguide1 svmguide1.t
it should work. The sample files can be downloaded at http://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/binary.html#svmguide1
references: http://www.csie.ntu.edu.tw/~cjlin/papers/guide/guide.pdf
Make sure Homebrew is installed, then just run:
brew install gnuplot
Link the executable, so that it is in the PATH (i.e. /usr/bin) and can be found by the Python scripts:
sudo ln -s /opt/local/bin/gnuplot /usr/bin/gnuplot
After that's done, libsvm's Python scripts should not complain any longer.
Since macOS high sierra, /usr/bin is not modifyable by the user anymore, gnuplot is installed at /usr/local/bin instead. Open easy.py and change the path from "/usr/bin" to "/usr/local/bin"
I want to install MIT Scheme on my Mac, I have downloaded the MacOS X binary(x86-64).
However, I could not make it work using Mac Terminal.
I have tried to follow these articles:
Installing MIT/GNU Scheme on Mac OS X Leopard
Installing MIT Scheme on Mac OS X
but it seems out of date and does not work.
So, I'm looking for a simple method which allows me to write Scheme code using Mac Terminal.
I have struggled for hours to try to install it.
UPDATED FOR EL CAPITAN:
The best way that I've found was from here:
Download either the 32-bit or 64-bit dmg file for Scheme.
Double click the .dmg file, and you'll get this window, in which you should drag the "MIT/GNU Scheme" file into the Applications folder.
For the 32-bit version, run this command:
sudo ln -s /Applications/MIT\:GNU\ Scheme.app/Contents/Resources /usr/local/lib/mit-scheme-i386
Then enter your administrator password, and run this command:
sudo ln -s /usr/local/lib/mit-scheme-i386/mit-scheme /usr/local/bin/scheme
For the 64-bit version, first run this command:
sudo ln -s /Applications/MIT\:GNU\ Scheme.app/Contents/Resources /usr/local/lib/mit-scheme-x86-64
Then enter your administrator password and run this command:
sudo ln -s /usr/local/lib/mit-scheme-x86-64/mit-scheme /usr/local/bin/scheme
And that's it! Now you should be able to use MIT Scheme in your terminal by typing "scheme" into the command line:
Homebrew makes it easy for you. On Terminal, type:
ruby <(curl -fsSkL raw.github.com/mxcl/homebrew/go) ; brew install mit-scheme
Done!
Edit
The install script has been moved:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" ; brew install mit-scheme
For Yosemite 10.10.3:
After installing X11.app and homebrew,
$ brew tap homebrew/x11
$ brew install mit-scheme
I found it easier when a maintained package manager such as homebrew covers all the dependency and build stuff.
Edit: simply
$ brew install mit-scheme
would do. X11 is now optional instead of dependence. There is still an --with-x11 option which requires whole Xcode.
You can install scheme using homebrew using the following command
brew install mit-scheme
If you have the latest version of Mac system, El Capitan 10.11.2, You might need to do something different than above.
The first command will be same.
For the 64-bit version, first run this command:
sudo ln -s /Applications/MIT\:GNU\ Scheme.app/Contents/Resources /usr/local/lib/mit-scheme-x86-64
Then enter your administrator password and run this command:
sudo ln -s /usr/local/lib/mit-scheme-x86-64/mit-scheme /usr/local/bin/scheme
Note: The difference is you need to put local between /usr/ and /bin/
Type scheme in the terminal to see if it works. If you get the following screenshot, that means you succeed it.
Success Result
You definitely need to put local there.
The reason is this, Apple improved OS security in OSX 10.10 (rootless), and changes to the general system-wide binaries (such as /usr/bin) is not permitted.
If you are having trouble with the accepted answer from #virgil-ming, try this:
$ brew install Caskroom/cask/xquartz
$ brew install mit-scheme
Same idea, of course, but this got me up and running when brew tap homebrew/x11 responded with multiple conflicts.
As always, remember to brew update then try again when you are having problems, a la Homebrew's troubleshooting guide.
If you are using docker, and I recommend you do:
docker run -it inikolaev/alpine-scheme
will drop you right into a scheme REPL.
UPDATE FOR MAC OS HIGH SIERRA:
Worked for me just by executing (if you are using Homebrew):
brew install mit-scheme
If you are using MacPorts, the command is similar to what others have posted for homebrew -
sudo port install mit-scheme
That set me up pretty well on OS X 10.8.5
I came across a problem that the 10.x versions of the MIT/GNU Scheme do not support Mac OS X 10.11 El Capitan. In fact, it requires Mac OS X 10.13 or higher.
The topmost version supporting older Mac OS X versions is MIT/GNU Scheme 9.2.
