问题 After installing pyenv from Homebrew on MacOS Mojave I am getting build errors when attempting to install any python versions.

How to implement locking in a multi process system?

由 可紊 提交于 2019-12-21 22:12:57
问题 We are running lots of jenkins projects in parallel. We are using python, and we have chosen to manage the virtual environments with pyenv. Unfortunately, pyenv has a well-known race condition. To work around the problem, I would like to implement locking at the process level. What I want to do is: lock some resource (a file?) do my pyenv stuff unlock the resource My scripts are written in bash. How can I implement resource locking / unlocking in bash? 回答1: So your friend in the unix world

问题 I've moved over to using pyenv when running python. The problem though is when I execute a module and that module imports other module pyenv will often print a huge chunk of what to me is gibberish. For example, alias py37="pyenv local 3.7.3 && python" Admins-MacBook-Pro-4:general kylefoley$ py37 Python 3.7.3 (default, Oct 16 2019, 03:01:07) [Clang 10.0.1 (clang-1001.0.46.4)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import keyboard bool b'B'

Looking for a cross-platform (Linux, MacOS, Windows) tool for managing Python environments

由 早过忘川 提交于 2019-12-13 03:59:01
问题 I was investigating the use of Anaconda environments for CI/CD (since, to my knowledge, it is the only platform that supports Linux, MacOS, and Windows). I tried to use Miniconda which is supposed to only install the bare minimum. However, I realised that, by default, Miniconda is not "mini" after all. For example, if I attempt to create a new Python environment ( conda create -n py36 python=3.6 anaconda ), it will install a bunch of not needed stuff like JupyterLab and others. So, before

The current way manage my projects: I have pyenv and pyenv-virtualenv installed. I have a few (currently 4) specific virtualenvs that each cater to a type of project. The projects themselves have .pyenv-version set, I have the autoload virtualenv feature of pyenv enabled. If I need to share a project, I generate a requirements
