Library not loaded: libcrypto.1.0.0.dylib issue in mac

You might have come across this error while dealing with the openssl module.

Inorder to solve this issue follow the following steps

Step 1: Install openssl using brew

brew install openssl

Step 2: Copy copy libssl.1.0.0.dylib and libcrypto.1.0.0.dylib

cd /usr/local/Cellar/openssl/1.0.1f/lib

sudo cp libssl.1.0.0.dylib libcrypto.1.0.0.dylib /usr/lib/

Note the bold folder name. There will be change in that depending on your openssl version

Edit (2019 July) If you are getting permission denied error even after sudo. Try copying to `/usr/local/lib ` instead. Thanks to George Hotz from comments to pointing it out.

Step 3: Remove the existing links

sudo rm libssl.dylib libcrypto.dylib

sudo ln -s libssl.1.0.0.dylib libssl.dylib

sudo ln -s libcrypto.1.0.0.dylib libcrypto.dylib

That’s it. Now try installing what you have been trying to install.

I hope this helps. If you need any further clarification, do comment.

Enjoy smile
