PyEnv BUILD FAILED installing Python on MacOS

问题:

While trying to install Python 3.6.6 (for Airflow) using PyEnv on MacOS, I am encountering build failure with following stack-trace

I've followed the steps mentioned in the docs for setting-up PyEnv on Mac via Homebrew.

Environment / Framework versions

• MacOS High Sierra 10.13.6
• Homebrew 1.7.1
• PyEnv 1.2.6
• Existing Python distributions
  • Python 2.7.15 [GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.39.2)] on darwin
  • Python 3.7.0 [Clang 9.0.0 (clang-900.0.39.2)] on darwin

回答1:

I was able to get away with above error by referring to Common build problems

• brew install readline xz
• xcode-select --install
• brew install openssl

---

After this, I installed and initialized pyenv

• brew install pyenv
• pyenv init (inside your project directory)

---

Finally install and activate required python version

• pyenv install 3.6.6
• pyenv local 3.6.6 (inside your project directory)

The only way I could get it working is through the below prefixes before installing

CFLAGS="-I$(brew --prefix readline)/include -I$(brew --prefix openssl)/include 
-I$(xcrun --show-sdk-path)/usr/include" \
LDFLAGS="-L$(brew --prefix readline)/lib -L$(brew --prefix openssl)/lib" \
PYTHON_CONFIGURE_OPTS=--enable-unicode=ucs2 \
pyenv install -v 3.7.1

The accepted answer didn't work for me (Mojave) but this did:

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

I found the solution from http://digidememory.blogspot.com/2019/01/macos-mojave-10142python371.html

In my case, I solved by this command

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

This worked for me:

1. remove CommandLineTools folder under /Library/Developer
2. run in terminal: xcode-select --install
3. sudo mv /usr/local/include /usr/local/include_old
