Where is zlib mac os x

This uses homebrew in the background to try to install python, which fails with zipimport. ZipImportError: can't decompress data; zlib not available. The same command worked before the upgrade. This question has been asked before and the generally accepted solution is to install xcode command line tools using this command: xcode-select --install.

Incidentally I also looked into installing python from a binary but there's no v3. If you use homebrew, you can install the PIL with just brew install pil.

I ran the above just now on OSX Sara N. Frank Frank 6, 8 8 gold badges 43 43 silver badges 55 55 bronze badges. Confirmed - works on mojave, using brew install zlib also did not work. This was the only thing that worked for me too. Brew was what caused me all the issues in the first place! This works for me on Big Sur. Nothing worked for me except this on Big Sur. I also did a brew install zlib that did nothing. Thank you!! ZipImportError: can't decompress data; zlib not available.

It provides in-memory compression and decompres- sion decompression sion functions, including integrity checks of the uncompressed data. This version of the library supports only one compression method deflation but other algorithms will be added later and will have the same stream interface. Compression can be done in a single step if the buffers are large enough for example if an input file is mmap'ed , or can be done by repeated calls of the compression function.
