The solution is to create a .env file to set the src folder in PYTHONPATH otherwise pytest is unable to find the model package. Also, putting conftest.py inside the src folder doesn't help as suggested by someone.

How to install local python packages when building jobs under Github Actions?

Asked 2021-Jun-12 at 17:27

I am building a python project -- potion. I want to use Github actions to automate some linting & testing before merging a new branch to master.

To do that, I am using a slight modification of a Github recommended python actions starter workflow -- Python Application.

During the step of "Install dependencies" within the job, I am getting an error. This is because pip is trying to install my local package potion and failing.

The code that is failing if [ -f requirements.txt ]; then pip install -r requirements.txt; fi

The corresponding error is:

Recently updated the macOS to Bigsur and as part of the update, I also updated the packages through homebrew. My coc.nvim plugin was not working so, I reinstalled the package. And after that, I am unable to see the color of my scheme (gruvbox) which is also installed as a plugin. Now the screen is all grey with the dark background (the background was dark even previously). I am attaching the vim settings for clarification. The syntax setting is enabled and it is rightly picking erlang, the termguicolors is set as well. I am using mac terminal to invoke vim.

How can I set up my imports in order to run my python application without installing it, and still be able to run tox using poetry?

Asked 2021-Jun-02 at 14:37

I have a python 3.6 code-base which needs to be installed in the environment's site-packages directory in order to be called and used. After moving it to docker, I decided that I should set up a shared volume between the docker container and the host machine in order to avoid copying and installing the code on the container and having to rebuild every time I made a change to the code and wanted to run it. In order to achieve this, I had to change a lot of the import statements from relative to absolute. Here is the structure of the application:

ANSWER

Answered 2021-Jun-02 at 14:37

You have to change the imports back to from app import something, the src part is, with respect to the code as a deliverable, completely transient. Same goes for adding in another app directory, your initial project structure was fine.

You were right about going from relative imports to absolute ones though, so all that is necessary thereafter is telling your python runtime within the container that root/src should be part of the PYTHONPATH:

This is a bug in pyflakes -- I'd suggest reporting it there

The subtlety is that assignment expressions break out of comprehension scopes, but pyflakes assumes that comprehension scopes enclose all assignments

I'd suggest reporting an issue here

as a workaround, you can place a # noqa comment on the line which produces the error, for example:

QUESTION

flake8 only linting partial file in VS Code

Asked 2021-Apr-26 at 17:12

I've successfully setup flake8 in my python project (with a .flake8 file in the root), and tied it to VS Code by way of a .vscode/settings.json file so that I see linter warnings in the file that I'm cleaning up. However, at line 1000, the linter support suddenly disappears. All lines following line 1000 do not provide linter feedback.

When I run flake8 /path/to/file from the command line, I get the full list of errors and their corresponding line numbers (including a number of warnings beyond line 1000), but for some reason VS Code seems to be unable to report these errors in-line in the IDE.

Is there some configuration I'm missing to allow VS Code to lint the rest of my large files beyond line 1000?

...

ANSWER

Answered 2021-Apr-26 at 17:12

After further testing, I found the issue. I was using black and flake8 in the settings.json file for vscode, and apparently, black was hitting a syntax error that I had introduced higher up in the file (around line 1000). This caused a silent failure of the linter sequence that VS code is running to present the "error squiggly lines".

When running a pre-commit hook (pre-commit run -a) that runs all 3 linters (black, iSort, and flake8), the syntax error was reported by black and easily fixed, but when run "on save" in VS-code, it fails silently and stops reporting inline errors in the IDE.

With the syntax error fixed, running flake8 from the command line returns the expected number of warnings/errors, and VS Code again shows the squiggly lines on errors, for the full file, regardless of length.
