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
Already downloaded: /Users/administrator/Library/Caches/Homebrew/openssl-1.0.2h_1.el_capitan.bottle.tar.gz
==> Pouring openssl-1.0.2h_1.el_capitan.bottle.tar.gz
==> Caveats
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/
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
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
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
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:$PATH"' >> ~/.bash_profile
The solution above from edwardthesecond worked for me too on Sierra
brew install openssl
cd /usr/local/include
ln -s ../opt/openssl/include/openssl
./configure && make
Other steps I did before were:
installing openssl via brew
brew install openssl
adding openssl to the path as suggested by homebrew
brew info openssl
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
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.
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.
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...
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
for me this is what worked...
I edited the ./bash_profile and added below command
export PATH="/usr/local/opt/openssl/bin:$PATH"
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
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 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
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
