pip installation requirements.txt échoue avec AssertionError: Egg-link ne correspond pas à l'emplacement d'installation

Question

Je travaille sur un projet Python/C++ qui est à la fois une bibliothèque et une application. Je vais avoir le problème en cours d'exécution

$ pip install -r requirements.txt 

me donne deux fois l'erreur suivante (ce qui est la deuxième manche):

$ pip install -r requirements.txt

Je dois courir autant de fois que possible parce que le pip install sera faire partie d'un Makefile ou faciliter la vie des utilisateurs finaux de l'application. J'ai trouvé seulement one post avec ce problème mais aucun chemin vers une solution.

Answer 1

Cela se passait pour moi parce qu'il y avait un dossier myProject.egg-info au mauvais endroit, que Pip semble tomber en essayant de le désinstaller. J'ai supprimé ce, reran pip install -r requirements.txt, et le dossier a été installé à l'emplacement correct spécifié.
