I’m trying to get a working version of python 3.7 to run in the machine executor. I’ve tried the following, but am getting errors: - compile from source - can’t find the resulting .so python file - installation via pyenv - ssl library error - installation via the deadsnakes ppa - ssl library error Here is a sample of my installation script, this currently fails due to the ‘\_ssl’ library not being linked/installed properly. ```auto version: 2 jobs: build: machine: true working_directory: ~/repo steps: - checkout - run: name: install ubuntu build reqs command: | sudo apt update && sudo apt upgrade -y sudo apt install build-essential libssl-dev zlib1g-dev libncurses5-dev libncursesw5-dev libreadline-dev libsqlite3-dev libgdbm-dev libdb5.3-dev libbz2-dev libexpat1-dev liblzma-dev tk-dev libffi-dev - run: name: install python 3.7 command: | sudo add-apt-repository --yes ppa:deadsnakes/ppa sudo apt-get update sudo apt-get install python3.7 wget https://bootstrap.pypa.io/get-pip.py sudo python3.7 get-pip.py sudo python3.7 -m pip install --upgrade pip setuptools wheel sudo python3.7 -m pip install pipenv ``` Has anyone gotten python 3.7 installed and working in the machine executor? ---

Hey, So the first question is, do you really need the `machine` executor? This is simpler with Docker. If you do need the `machine` executor, pyenv is already installed and Python v3.7.0 is pre-installed. You can try this: ```auto version: 2 jobs: build: machine: true working_directory: ~/repo steps: - checkout - run: name: "Set Python Version" command: pyenv global 3.7.0 - run: name: "Do things!" command: python run.py ``` ---

Thanks! It’s definitely debatable if I’m doing the appropriate configuration. I started with a testing scheme locally using docker-compose. Where the service under-development is tested by bringing up only the supporting services, and running the key service tests with the key service communicating with the docker-compose raised supporting services. As I understand, I can spin up the whole docker-compose full service using the docker executor. But with the way my project is structured I need to run tests outside and communicate with the docker-compose network. Anyway, your suggestion, is more what I expected and was looking for. However, when I run the config below I get the error: ERROR: ``` #!/bin/bash -eo pipefail pyenv global 3.7.0 pyenv: version `3.7.0' not installed ``` Config: ``` version: 2 jobs: build: machine: true working_directory: ~/repo steps: - checkout - run: name: install python 3.7 command: | pyenv global 3.7.0 sudo python -m pip install --upgrade pip setuptools wheel sudo python -m pip install pipenv ``` ---

So as mentioned initially, I did try to install python 3.7.0 through pyenv, but the build process fails with the following error: ``` Updating /opt/circleci/.pyenv/plugins/pyenv-update...

Hey, So my apologies. What I provided before only worked because I was using a different VM. The best solution I can find is to use an updated `machine` image. The one in the example below already has Python 3.7.0: ```auto version: 2 jobs: build: machine: image: circleci/classic:201808-01 steps: - checkout - run: name: "Switch to Python v3.7" command: | pyenv versions pyenv global 3.7.0 ``` You can see an example of this build running [here](https://circleci.com/gh/felicianotech/cci-testing-pub/729). ---

@FelicianoTech Thanks! With the image specification I was able to run python 3.7 with the machine executor! Just what I was looking for! ---
