In my case, I have: Currently installed python versions on my systemįrom the screenshot above, the asterisk shows the currently active Python version, which is the default system version: python -version To see the list of the Python versions we have, we use the following command: pyenv versions Then we'll use this command: pyenv install 3.10.2 The version argument follows semantic versioning which is "".įor Python 3, let's say we want to install 3.10.2. You can install Python using pyenv with the following syntax: pyenv install With pyenv installed, you don't need to install Python with Homebrew anymore (as you may already be doing). Make sure you follow the rest of the steps for installing pyenv in the documentation. Here's the command to install Python 3 on Mac: brew install pyenv Install pyenv using Homebrew with the following command: This tool helps you to work on different environments which require different versions of Python. pyenv does the same thing for Python – it's a version management tool. If it works in the python REPL, then it should work when actually run.If you're familiar with NodeJS, you'll know that nvm is used for managing versions of Node in different environments. Similar to the Intel instructions, virtual environments help isolate packages between projects Install the x86 compatible version of Python you want.Īrch -x86_64 brew install Make sure you’re using a virtual environment.# Install the x86-compatible version of homebrewĪrch -x86_64 /bin/bash -c "$(curl -fsSL )" You might need to uninstall your current version of homebrew first Reinstall homebrew, but the x86 compatible version of homebrew! The explanation for why this is needed is on the python-ibmdb page.The steps for this are a bit more complicated an very easy to get wrong unfortunately Your results may varyĬonnecting to IBM DB2 on MacOS (M1 / Apple Silicon) with Python Testing with Python 3.9, I don’t have this problem, and don’t need to run this script. Note, I’ve only had this issue when using Python 3.7 and python 3.8. Ln -s "/usr/local/lib/$py_folder/site-packages/clidriver/lib/libdb2.dylib" libdb2.dylibĮxport DYLD_LIBRARY_PATH="venv/lib/$py_folder/site-packages/clidriver/lib:$DYLD_LIBRARY_PATH"Īfter this, you should successfully be able to connect to DB2 via Python. If test -f "$PWD/clidriver/lib/libdb2.dylib" then Install_name_tool -change libdb2.dylib "$(pwd)/clidriver/lib/libdb2.dylib" "$db2_binary" # Only need to execute this when running on macĭb2_binary=$(ls ibm_db.cpython* | head -n 1) If you don’t do this, the below script won’t work # Create the virtual environment in your project folder # Double check this is the python version you're wanting to use I primarily use Pycharm IDE, so isolating this issue to a virtual environment made it easier to fix for me. Make sure you’re using a virtual environment.Source ~/.bashrc # If bash is your default shell Source ~/.zshrc # If zsh is your default shell # Example: brew install install Add the installed Python brew to your PATHĮcho 'export > ~/.zshrc # If zsh is your default shellĮcho 'export > ~/.bashrc # If bash is your default shell Doing so allows give you a more standard location for the Python3.x executable Here are the steps I used to solve this problem: Referenced from: venv/lib/python3.7/site-packages/ibm_db.cpython-37m-darwin.so Reason: image not foundĪfter hours and even days of Googling, I finally compiled a number of Github issues and Stack overflow posts to come to the solution to this problem.Ĭonnecting to IBM DB2 on MacOS (Intel) with Python If you’ve tried to connect to a DB2 database using the ibm-db package, you might have run into this issue at some point: ImportError: dlopen(venv/lib/python3.7/site-packages/ibm_db.cpython-37m-darwin.so, 2): Library not loaded: libdb2.dylib Update (): I've updated these instructions to also handle issues with Macbooks using the M1 / Apple Silicon chip
