  • 采用如下方式安装
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)

依然报错：

  • 重新安装zlib
brew uninstall --force zlib
brew cleanup -s zlib
brew cleanup --prune-prefix
brew install zlib

添加环境变量

export LDFLAGS="-L/usr/local/opt/zlib/lib"
