Docker

Ever had one of these issues with Pycharm 2018 and Docker?

Couldn't refresh skeletons for remote interpreter
The docker-compose process terminated unexpectedly: /usr/local/bin/docker-compose -f docker-compose.yml -f .PyCharm2018.3/system/tmp/docker-compose.override.8.yml run --rm --name skeleton_generator_643129755 python
Regenerate skeletons

or

can't open file '/opt/.pycharm_helpers/pycharm/django_test_manage.py' + "No such file or directory"

Then you should clear all pycharm helpers from your docker containers and images:

docker ps -a | grep -i pycharm | awk '{print $1}' | xargs docker rm
docker images | grep -i pycharm | awk '{print $3}' | xargs docker rmi

Sometimes I just love how the open source community works nowadays! Sometimes you  use your favourite search engine to find a package/repository/etc..., just to find out thatit contains a quickstart info, a proper package.json or docker-compose.yml. All you need to do is "npm install && npm run" or "docker-compose build && docker-compose up" and you are good to go.

This helps devs to contribute to open source software soooooo much!

TL;DR: Use Docker, package.json, requirements.txt, and for the love of god, write a Quickstart section into your Readme!

One major difference when using Windows vs. Linux is that Windows "prefers" \r\n (CRLF) for newlines. This has been a known fact for years, and most tools will automatically handle this  (e.g., Filezilla). However, docker on Windows does not handle this, which will cause massive issues that are literally impossible to debug. For instance, you might get this error:

standard_init_linux.go:175: exec user process caused "no such file or directory"

This issue is really easy to fix: Convert your files from \r\n (CRLF) to just \n (LF). Most editors/IDEs on Windows can do that for you (including Notepad++). However, this will not be a permanent solution. If you are using GIT, you need to configure either your repository or your global GIT configuration to prefer \n over \r\n:

Unless you really need to keep your \r\n, I recommend to change this globally with

git config --global core.autocrlf input
