System: macOS mojave 10.14.6
when I use brew install llvm, this error appears:
Error: cmake: undefined method `on_linux' for #<Class:0x00007f7f744bf6b8>
I happened to have a Mojave machine and re-did the installation process myself, and it works fine.
Here is what I did:
brew install llvm (I actually used brew reinstall llvm, since it is reinstall for me)
echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.bash_profile, brew version would be on your PATH
source ~/.bash_profile, apply the PATH change

To use the bundled libc++ please add the following LDFLAGS:
LDFLAGS="-L/usr/local/opt/llvm/lib -Wl,-rpath,/usr/local/opt/llvm/lib"
llvm is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.
If you need to have llvm first in your PATH run:
echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> /Users/rchen/.bash_profile
For compilers to find llvm you may need to set:
export LDFLAGS="-L/usr/local/opt/llvm/lib"
export CPPFLAGS="-I/usr/local/opt/llvm/include"

How to prevent Homebrew from installing a certain dependency formula when installing any future formulae? On my mac, python is provided by conda and I don't want duplicate pythons. Every time I install a python-dependent formula it gets automatically installed.
First, have a look the dependencies you need for the formula. (use brew deps --tree xpdf for a tree view)
brew deps -n formula
dep1
dep2
Then install the dependencies you want manually.
brew install dep1
And finally install the formula using --ignore-dependencies.
brew install --ignore-dependencies formula
#Pau's answer worked for me. One thing to add is that brew deps
will show all dependencies including optional and already installed ones so it made it hard for me when there were more than a dozen.
I ended up using brew info
brew info openjdk
#... basic info
==> Dependencies
Build: autoconf ✘, pkg-config ✔
Required: giflib ✔, harfbuzz ✔, jpeg-turbo ✔, libpng ✔, little-cms2 ✔
==> Requirements
Build: Xcode ✘
Required: macOS >= 10.15 ✔
#... more info
Then the key part of the answer that #Pau pointed out is to install with
brew install --ignore-dependencies openjdk
I've installed snappy (I think) with brew install snappy.
And brew info snappy gives

Yet there is no snappy in /usr/local/bin. Where is it?
Ah! Need to run brew install snzip to create a command line wrapper to the snappy library.
Can run snzip -k FILE to compress a file and keep it. snzip -d FILE.sz to decompress.
I just installed Homebrew on Lion 10.7.5 (it did complain that it is not supported, so I am aware that this may be the reason). I tried to install pandoc, and apparently cryptonite is causing problems.

I hope I can install pandoc on 10.7.5. This is a MBP early 2011 with 4 GB RAM. Newer versions run very slowly, so I'd prefer not to upgrade from Lion, unless I have to.
UPDATE: I ended up upgrading to Mavericks. Everything worked just fine (some hiccups, nothing major). Homebrew installed fine, then pandoc was installed with Homebrew and now everything is humming.
Inspired by https://discourse.brew.sh/t/how-to-install-old-version-of-a-formula, I found a workaround.
As Homebrew doesn't offer Pandoc < 2.0 anymore, we need to sneak it into the current formula like so:
$ cd "$(brew --repo homebrew/core)"
In Formula/pandoc.rb, replace the contents of url with https://hackage.haskell.org/package/pandoc-1.19.2.4/pandoc-1.19.2.4.tar.gz and the contents of sha256 with bbe08c1f7fcfea98b899f9956c04159d493a26f65d3350aa6579aa5b93203556
Now you can install Pandoc: $ brew install pandoc.
I'm on: OSX 10.11.6, Homebrew version 0.9.9m OpenSSL 0.9.8zg 14 July 2015
I'm trying to play with with dotnetcore and by following their instructions,
I've upgraded/installed the latest version of openssl:
> brew install openssl
==> Downloading https://homebrew.bintray.com/bottles/openssl-1.0.2h_1.el_capitan.bottle.tar.gz

A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
/usr/local/etc/openssl/certs
and run
/usr/local/opt/openssl/bin/c_rehash
This formula is keg-only, which means it was not symlinked into /usr/local.
Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries
Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:
LDFLAGS: -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include
But when I try to link openssl I continue to run into this linking error:
> brew link --force openssl
Warning: Refusing to link: openssl
Linking keg-only OpenSSL means you may end up linking against the insecure,
deprecated system version while using the headers from the Homebrew version.
Instead, pass the full include/library paths to your compiler e.g.:
-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib
The option to include compiler flags doesn't make sense to me, since I'm not compiling these libraries that I'm dependent on.
EDIT dotnetcore has updated their instructions:
brew update
brew install openssl
ln -s /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib /usr/local/lib/
ln -s /usr/local/opt/openssl/lib/libssl.1.0.0.dylib /usr/local/lib/
This is what worked for me:
brew update
brew install openssl
ln -s /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib /usr/local/lib/
ln -s /usr/local/opt/openssl/lib/libssl.1.0.0.dylib /usr/local/lib/
ln -s /usr/local/Cellar/openssl/1.0.2j/bin/openssl /usr/local/bin/openssl
Thanks to #dorlandode on this thread https://github.com/Homebrew/brew/pull/597
NB: I only used this as a temporary fix until I could spend time correctly installing Openssl again from scratch. As I remember I spent best part of a day debugging and having issues before I realised the best way was to manually install the certs I needed one by one. Please read the link in #bouke's comment before attempting this.
As the update to the other answer suggests, the workaround of installing the old openssl101 brew will no longer work. For a right-now workaround, see this comment on dotnet/cli#3964.
The most relevant part of the issue copied here:
I looked into the other option that was suggested for setting the rpath on the library. I think the following is a better solution that will only effect this specific library.
sudo install_name_tool -add_rpath /usr/local/opt/openssl/lib /usr/local/share/dotnet/shared/Microsoft.NETCore.App/1.0.0/System.Security.Cryptography.Native.dylib
and/or if you have NETCore 1.0.1 installed perform the same command for 1.0.1 as well:
sudo install_name_tool -add_rpath /usr/local/opt/openssl/lib /usr/local/share/dotnet/shared/Microsoft.NETCore.App/1.0.1/System.Security.Cryptography.Native.dylib
In effect, rather than telling the operating system to always use the homebrew version of SSL and potentially causing something to break, we're telling dotnet how to find the correct library.
Also importantly, it looks like Microsoft are aware of the issue and and have both a) a somewhat immediate plan to mitigate as well as b) a long-term solution (probaby bundling OpenSSL with dotnet).
Another thing to note: /usr/local/opt/openssl/lib is where the brew is linked by default:
13:22 $ ls -l /usr/local/opt/openssl
lrwxr-xr-x 1 ben admin 26 May 15 14:22 /usr/local/opt/openssl -> ../Cellar/openssl/1.0.2h_1
If for whatever reason you install the brew and link it in a different location, then that path is the one you should use as an rpath.
Once you've update the rpath of the System.Security.Cryptography.Native.dylib libray, you'll need to restart your interactive session (i.e., close your console and start another one).
None of these solutions worked for me on OS X El Capitan 10.11.6. Probably because OS X has a native version of openssl that it believes is superior, and as such, does not like tampering.
So, I took the high road and started fresh...
Manually install and symlink
cd /usr/local/src
If you're getting "No such file or directory", make it:
cd /usr/local && mkdir src && cd src
Download openssl:
curl --remote-name https://www.openssl.org/source/openssl-1.0.2h.tar.gz
Extract and cd in:
tar -xzvf openssl-1.0.2h.tar.gz
cd openssl-1.0.2h
Compile and install:
./configure darwin64-x86_64-cc --prefix=/usr/local/openssl-1.0.2h shared
make depend
make
make install
Now symlink OS X's openssl to your new and updated openssl:
ln -s /usr/local/openssl-1.0.2h/bin/openssl /usr/local/bin/openssl
Close terminal, open a new session, and verify OS X is using your new openssl:
openssl version -a
Just execute brew info openssland read the information where it says:
If you need to have this software first in your PATH run: echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
If migrating your mac breaks homebrew:
I migrated my mac, and it unlinked all my homebrew installs - including OpenSSL. This broke gem install, which is how I first noticed the problem and started trying to repair this.
After a million solutions (when migrating to OSX Sierra - 10.12.5), the solution ended up being comically simple:
brew reinstall ruby
brew reinstall openssl
Edit much later: as Gal Bracha noted in the comments, you ?might? need to delete /usr/local/opt/openssl before doing the reinstalls, just to be safe. I didn't need to at the time, but if you're still having trouble, give that a try.
After trying everything I could find and nothing worked, I just tried this:
touch ~/.bash_profile; open ~/.bash_profile
Inside the file added this line.
export PATH="$PATH:/usr/local/Cellar/openssl/1.0.2j/bin/openssl"
now it works :)
Jorns-iMac:~ jorn$ openssl version -a
OpenSSL 1.0.2j 26 Sep 2016
built on: reproducible build, date unspecified
//blah blah
OPENSSLDIR: "/usr/local/etc/openssl"
Jorns-iMac:~ jorn$ which openssl
/usr/local/opt/openssl/bin/openssl
The solution above from edwardthesecond worked for me too on Sierra
brew install openssl
cd /usr/local/include
ln -s ../opt/openssl/include/openssl
./configure && make
Other steps I did before were:
installing openssl via brew
brew install openssl
adding openssl to the path as suggested by homebrew
brew info openssl
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
I have a similar case. I need to install openssl via brew and then use pip to install mitmproxy. I get the same complaint from brew link --force. Following is the solution I reached: (without force link by brew)
LDFLAGS=-L/usr/local/opt/openssl/lib
CPPFLAGS=-I/usr/local/opt/openssl/include
PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig
pip install mitmproxy
This does not address the question straightforwardly. I leave the one-liner in case anyone uses pip and requires the openssl lib.
Note: the /usr/local/opt/openssl/lib paths are obtained by brew info openssl
This worked for me:
brew install openssl
cd /usr/local/include
ln -s ../opt/openssl/include/openssl .
By default, homebrew gave me OpenSSL version 1.1 and I was looking for version 1.0 instead. This worked for me.
To install version 1.0:
brew install https://github.com/tebelorg/Tump/releases/download/v1.0.0/openssl.rb
Then I tried to symlink my way through it but it gave me the following error:
ln -s /usr/local/Cellar/openssl/1.0.2t/include/openssl /usr/bin/openssl
ln: /usr/bin/openssl: Operation not permitted
Finally linked openssl to point to 1.0 version using brew switch command:
brew switch openssl 1.0.2t
Cleaning /usr/local/Cellar/openssl/1.0.2t
Opt link created for /usr/local/Cellar/openssl/1.0.2t
I had the same problem while trying to install newer version of ruby 2.6.5
https://github.com/kelaberetiv/TagUI/issues/86 helps me to solve the problem. This if for macOS catalina Version 10.15.1
Basically, I did update and upgrade homebrew and install openssl and install ruby.
brew update && brew upgrade
brew install openssl
Then create these 2 symlinks
ln -s /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib /usr/local/lib/
ln -s /usr/local/opt/openssl/lib/libssl.1.0.0.dylib /usr/local/lib/
then installed ruby 2.6.5
Note: this no longer works due to https://github.com/Homebrew/brew/pull/612
I had the same problem today. I uninstalled (unbrewed??) openssl 1.0.2 and installed 1.0.1 also with homebrew. Dotnet new/restore/run then worked fine.
Install openssl 101:
brew install homebrew/versions/openssl101
Linking:
brew link --force homebrew/versions/openssl101
for me this is what worked...
I edited the ./bash_profile and added below command
export PATH="/usr/local/opt/openssl/bin:$PATH"
export https_proxy=http://127.0.0.1:1087 http_proxy=http://127.0.0.1:1087 all_proxy=socks5://127.0.0.1:1080
works for me
and I think it can solve all the problems like
Failed to connect to raw.githubusercontent.com port 443: Connection refused
The solution might be updating some tools.
Here's my scenario from 2020 with Ruby and Python:
I needed to install Python 3 on Mac and things escalated. In the end, updating homebrew, node and python lead to the problem with openssl. I did not have openssl 1.0 anymore, so I couldn't "brew switch" to it.
So what was still trying to use that old 1.0 version?
It tuned out it was Ruby 2.5.5.
So I just installed Ruby 2.5.8 and removed the old one.
Other things you can try if this is not enough: Use rbenv and pyenv. Clean up gems and formulas. Update homebrew, node, yarn. Upgrade bundler. Make sure your .bash_profile (or equivalent) is set up according to each tool's instructions. Reopen the terminal.
