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

File "/private/var/folders/6y/kf699bqj2sgcgjshb20fr5zh0000gn/T/python-build.20180721180716.86347/Python-3.6.6/Lib/xmlrpc/client.py", line 138, in from xml.parsers import expat File "/private/var/folders/6y/kf699bqj2sgcgjshb20fr5zh0000gn/T/python-build.20180721180716.86347/Python-3.6.6/Lib/xml/parsers/expat.py", line 4, in from pyexpat import * ModuleNotFoundError: No module named 'pyexpat' make: *** [install] Error 1

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

I had this problem with Mojave and Python 3.7.3.

This worked for me:

SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk MACOSX_DEPLOYMENT_TARGET=10.14 pyenv install 3.7.3

回答2:

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 /

回答3:

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

回答4:

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)

short answer:

$ brew upgrade

now you can try to install python through pyenv

$ pyenv install 3.7.4

then, you have to set the python path

pyenv global 3.7.4

now, close and open a new terminal and write the command

echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n  eval "$(pyenv init -)"\nfi' >> ~/.bash_profile

That's all. For me it was fine.

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 /

回答7:

In my case this was caused by migration of data from old to new Mac. Both Xcode Command Line Tools and Homebrew migrated, but something broke. Reinstalling them from scratch worked for me.

Reinstall CLI tools:

$ sudo rm -rf /Library/Developer/CommandLineTools

$ xcode-select --install

Reinstall and update Homebrew:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

brew update

Istall pyenv + packages and python 3:

brew install pyenv
brew install openssl readline sqlite3 xz zlib
pyenv install 3.7.5

回答8:

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
