sudo pip install psycopg2
and I get a bunch of output that looks like:
cc -DNDEBUG -g -fwrapv -Os ..... ..... cc -DNDEBUG -g -fwrapv -Os ..... .....
And at the end it says:
ld: library not found for -lssl clang: error: linker command failed with exit code 1 (use -v to see invocation) error: command "cc" failed with exit status 1 ---------------------------------------- Cleaning up... Command /usr/bin/python -c "import setuptools, tokenize;__file__="/private/var/folders/bz/pvj1g9xj16d10pjjgbrfl3fw0000gn/T/pip_build_root/psycopg2/setup.py";exec(compile(getattr(tokenize, "open", open)(__file__).read().replace(" ", " "), __file__, "exec"))" install --record /var/folders/bz/pvj1g9xj16d10pjjgbrfl3fw0000gn/T/pip-uE3thn-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /private/var/folders/bz/pvj1g9xj16d10pjjgbrfl3fw0000gn/T/pip_build_root/psycopg2 Storing debug log for failure in /Users/Tyler/Library/Logs/pip.log
Running easy_install or doing it from source both give me the same error at the end (the part about library not found for -lssl).
Running brew install (or upgrade) openssl yields the below
$ brew upgrade openssl Error: openssl-1.0.1h already installed
Can anyone help me out?
For anyone looking for a solution for this on macOS Sierra 10.12 (or later, most likely): I fixed this by installing the command line tools:
pip install psycopg2 should work.
If it doesn"t, you could also try to link against brew"s openssl:
env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip install psycopg2
with openssl installed via brew. Note that the
brew link openssl --force does not work anymore:
$ brew link openssl --force 17.5s Warning: Refusing to link: openssl Linking keg-only openssl means you may end up linking against the insecure, deprecated system OpenSSL while using the headers from Homebrew"s openssl. Instead, pass the full include/library paths to your compiler e.g.: -I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib
As @macho points out below if this still does not work, you might need to use the
--no-cache option of pip, e.g.
env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip --no-cache install psycopg2
Remember to adjust these paths accordingly should you for instance build on ARM/Apple M1 Macs (as homebrew is installed at
/opt/homebrew/); command as follows:
env LDFLAGS="-I/opt/homebrew/opt/openssl/include -L/opt/homebrew/opt/openssl/lib" pip --no-cache install psycopg2
I had OpenSSL installed from brew (
brew install openssl)
The following worked for me:
export LDFLAGS="-L/usr/local/opt/openssl/lib" export CPPFLAGS="-I/usr/local/opt/openssl/include" pip install psycopg2
