XcodeMacosZlibPyenvXcode Problem Overview
My goal
I am trying to install Python 2.7.5 and 3.6.5 side-by-side on my MBP with with pyenv.
pyenv Installation
Following https://stackoverflow.com/questions/18671253/how-can-i-use-homebrew-to-install-both-python-2-and-3-on-mac , I tried:
$ pyenv install 3.6.5
Which erred with:
python-build: use openssl from homebrew
python-build: use readline from homebrew

What have I tried
- Installing zlib:
brew install zlib
My question
How can I install multiple Python environment with pyenv on MBP?
Xcode Solutions
Solution 1 - Xcode
On Mojave, after installing Xcode command line tools, had to run the following:
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
Solution 2 - Xcode
brew install zlib
export LDFLAGS="-L/usr/local/opt/zlib/lib"
export CPPFLAGS="-I/usr/local/opt/zlib/include"
pyenv install 3.7.2
Samsin's answer didn't work for me. I didn't have a Packages dir
Solution 3 - Xcode
On MacOS 11.1 (Big Sur) I eventually needed:
brew install bzip2
export LDFLAGS="-L $(xcrun --show-sdk-path)/usr/lib -L brew --prefix bzip2/lib"
export CFLAGS="-L $(xcrun --show-sdk-path)/usr/include -L brew --prefix bzip2/include"
pyenv install 3.9.0
I added the export commands in ./bash_profile so next time I can just use pyenv if I need to install more versions.
Keep an eye on : https://github.com/pyenv/pyenv/issues/1643 which tracks this, hopefully this will be fixed in pyenv.
Solution 4 - Xcode
I tried all the solution here with no success.
This is what worked for me on MacOs 11.2.1 (Big Sur):
export MACOSX_DEPLOYMENT_TARGET=11.0
brew install pyenv bzip2 zlib xz [email protected]
## 3.6.8
CFLAGS="-I$(brew --prefix openssl)/include -I$(brew --prefix bzip2)/include -I$(brew --prefix readline)/include -I$(xcrun --show-sdk-path)/usr/include" LDFLAGS="-L$(brew --prefix openssl)/lib -L$(brew --prefix readline)/lib -L$(brew --prefix zlib)/lib -L$(brew --prefix bzip2)/lib" pyenv install --patch 3.6.8 < <(curl -sSL https://github.com/python/cpython/commit/8ea6353.patch\?full_index\=1)
## 3.6.12
CFLAGS="-I$(brew --prefix openssl)/include -I$(brew --prefix bzip2)/include -I$(brew --prefix readline)/include -I$(xcrun --show-sdk-path)/usr/include" LDFLAGS="-L$(brew --prefix openssl)/lib -L$(brew --prefix readline)/lib -L$(brew --prefix zlib)/lib -L$(brew --prefix bzip2)/lib" pyenv install --patch 3.6.12 < <(curl -sSL https://github.com/python/cpython/commit/8ea6353.patch\?full_index\=1)
## 3.7.9
CFLAGS="-I$(brew --prefix openssl)/include -I$(brew --prefix bzip2)/include -I$(brew --prefix readline)/include -I$(xcrun --show-sdk-path)/usr/include" LDFLAGS="-L$(brew --prefix openssl)/lib -L$(brew --prefix readline)/lib -L$(brew --prefix zlib)/lib -L$(brew --prefix bzip2)/lib" pyenv install 3.7.9
The solution is taken from this gist.
Solution 5 - Xcode
The pyenv wiki has a page specific for common build problems. There are some possible solutions mentioned for the missing zlib error.
I have the same ZipImportError but with the following command installation is successful:
CFLAGS="-I$(xcrun --show-sdk-path)/usr/include" pyenv install 3.6.5
Solution 6 - Xcode
In order to get Python 3.8.6 with tkinter, I built on Vincent Gerris's answer and this blog post, and found success with
brew install bzip2
export LDFLAGS="-L $(xcrun --show-sdk-path)/usr/lib -L brew --prefix bzip2/lib"
export CFLAGS="-L $(xcrun --show-sdk-path)/usr/include -L brew --prefix bzip2/include"
export PYTHON_CONFIGURE_OPTS="--with-tcltk-includes='-I/usr/local/opt/tcl-tk/include' --with-tcltk-libs='-L/usr/local/opt/tcl-tk/lib -ltcl8.6 -ltk8.6' --enable-framework"
pyenv install 3.8.6
Solution 7 - Xcode
The following works for me on macOS Big Sur (11.6.1):
brew update
brew install bzip2
echo 'export PATH="/usr/local/opt/bzip2/bin:$PATH"' >> ~/.zshrc
export LDFLAGS="-L/usr/local/opt/zlib/lib"
export CPPFLAGS="-I/usr/local/opt/zlib/include"
pyenv install 3.8.6
