python - How to import requirements.txt from an existing project using Poetry

Question

I am trying out Poetry in an existing project. It used pyenv and virtual env originally so I have a requirements.txt file with the project's dependencies.

I want to import the requirements.txt file using Poetry, so that I can load the dependencies for the first time. I've looked through poetry's documentation, but I haven't found a way to do this. Could you help me?

I know that I can add all packages manually, but I was hoping for a more automated process, because there are a lot of packages...

Answer 1

poetry doesn't support this directly. But if you have a handmade list of required packages (at best without any version numbers), that only contain the main dependencies and not the dependencies of a dependency you could do this:

$ cat requirements.txt|xargs poetry add
