L'installation des modules python échoue - "limits.h" est manquant?

J'essaie d'installer un certain nombre de modules python 3 (par exemple regex, cytoolsz, spacy) qui nécessitent une compilation, mais ils échouent tous avec une erreur identique à celle ci-dessous (en bas). J'ai essayé pour vérifier la présence de "limits.h" en utilisant le grep ci-dessous. J'ai réinstallé gcc, g ++ build-essentials, python3-dev etc, mais en vain.

Avant tout pour répondre complètement à votre question. Le fichier limits.h dans /usr/include/linux/ est fourni par le linux-libc-dev paquet. Donc, pour avoir les fichiers d'en-tête à cet emplacement, vous devez simplement l'installer en:

Sudo apt install linux-libc-dev

pour avoir les fichiers d'en-tête fournis dans /usr/include/ qui sont également utilisés occasionnellement, vous avez besoin du libc6-dev package qui les fournit. Installez-le par:

Sudo apt install libc6-dev

En outre, il est déconseillé d'utiliser pip3 avec Sudo car il a tendance à créer des dossiers appartenant à la racine dans votre répertoire personnel. Pour résoudre ce problème, je suppose que vous avez déjà effectué quelques installations de cette manière, reprenez simplement la propriété de /home/$USER/.cache/pip par:

Sudo chown -Rv <your-username>:<your-username> /home/<your-username>/.cache/pip
