What have I tried

Installing zlib: brew install zlib

My question

How can I install multiple Python environment with pyenv on MBP?

回答1:

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 /

回答2:

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

回答3:

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
