19 February 2020 6 comments Python, MacOSX
I'm still working on getting pyenv in my bloodstream. It seems like totally the right tool for having different versions of Python available on macOS that don't suddenly break when you run brew upgrade
periodically. But every thing I tried failed with an error similar to this:
python-build: use openssl from homebrew
python-build: use readline from homebrew

I read through the Troubleshooting FAQ and the "Common build problems" documentation. xcode was up to date and I had all the related brew packages upgraded. Nothing seemed to work.
Until I saw this comment on an open pyenv issue: "Unable to install any Python version on MacOS"
All I had to do was replace the 10.14 for 10.15 and now it finally worked here on Catalina 10.15. So, the magical line was this:
SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk \ MACOSX_DEPLOYMENT_TARGET=10.15 \ PYTHON_CONFIGURE_OPTS="--enable-framework" \ pyenv install -v 3.7.6
Hopefully, by blogging about it you'll find this from Googling and I'll remember the next time I need it because it did eat 2 hours of precious evening coding time.
You are awesome! I was getting nowhere, and that was exactly the solution I needed.
Seconding Peter's comment!
Thank you for this post! It saved me a lot of time!
Thanks for the contribution!
On the new MacOS version (11.0 aka Big Sur), the command line becomes:
SKDROOT=/Library/Developer/CommandLineTools/SDKs/MacOSX11.0.sdk \
MACOSX_DEPLOYMENT_TARGET=11.0 \
PYTHON_CONFIGURE_OPTS="--enable-framework" \
pyenv install 3.7.6
But then another error comes up:
python-build: use openssl@1.1 from homebrew
python-build: use readline from homebrew

Every time I attempt this, it gets as far as checking through the various dependencies and this happens:
checking for python3... python3
checking for --enable-universalsdk... no
checking for --with-universal-archs... no
checking MACHDEP... checking for --without-gcc... no
checking for --with-icc... no
checking for gcc... clang
checking whether the C compiler works... no
Between the script deciding that gcc is clang, and that the C compiler's bad, a dialog comes up insisting I need to install the XCode command line tools. I've installed them multiple times, but it makes no difference. The script decides the C compiler is no good, and then dies like this:
configure: error: in `/var/folders/st/vtyr0y6902v7ylvbbq31vv9r0000gn/T/python-build.20210213162036.58382/Python-3.7.6':
configure: error: C compiler cannot create executables
See `config.log' for more details
Any ideas?
A version of the solution found in the comment at https://github.com/pyenv/pyenv/issues/1348#issuecomment-514057168 fixed this for me.
Don't let homebrew link binutils.
