Impossible d'installer npm - Impossible de corriger les problèmes, vous avez des paquets cassés?

J'essaie de mettre à niveau mes nodejs vers 7.6, mais j'ai échoué. Maintenant, j'ai un nouveau problème après avoir réinstallé le noeud 6.10:

$ sudo apt-get purge nodejs npm
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package 'npm' is not installed, so not removed
The following packages were automatically installed and are no longer required:
  linux-headers-4.8.0-40 linux-headers-4.8.0-40-generic linux-image-4.8.0-40-generic linux-image-extra-4.8.0-40-generic
Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED
  nodejs*
0 to upgrade, 0 to newly install, 1 to remove and 53 not to upgrade.
After this operation, 51.7 MB disk space will be freed.

Pourquoi dit-il Package 'npm' is not installed, so not removed? j'utilise npm pour installer de nombreux packages de nœuds pour mes projets !!

J'ignore l'erreur et j'ai continué l'installation du nœud 7.6:

$ curl -sL https://deb.nodesource.com/setup_7.6 | sudo -E bash - 
bash: line 1: html: No such file or directory
bash: line 2: syntax error near unexpected token `<'
'ash: line 2: `<head><title>404 Not Found</title></head>

Je suis donc retombé au nœud 6.x. Mais je ne peux plus installer npm:

$ sudo apt-get install npm

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

veuillez essayer ceci sudo apt install -f, puis essayez de réinstaller!

J'ai eu le même problème avec npm et j'ai dû installer les packages suivants dans l'ordre:

sudo apt install libssl1.0-dev
sudo apt install nodejs-dev
sudo apt install node-gyp
sudo apt install npm

J'espère que cela t'aides

Je me bats avec ça depuis quelques heures et cela a fonctionné comme un charme. Merci!

(Sur Kubuntu 18.04) J'avais précédemment installé libssl-dev, qui s'avère correspondre à libssl1.1, mais npm nécessite apparemment 1.0. J'ai dû supprimer libssl-dev et le remplacer par libssl1.0-dev, et tout a bien fonctionné. Les erreurs apt n'étaient pas utiles pour déterminer ce qui n'allait pas, donc votre réponse nous a sauvé la vie.

Oui! Merci! (Ubuntu 18.04.3 LTS)

Merci beaucoup, ça m'aide

J'ai eu le même problème avec npm.

Je vous suggère d'installer aptitude qui peut vous aider à résoudre les conflits

sudo apt install aptitude

puis installez votre package avec aptitude

sudo aptitude install npm

La meilleure solution doit essayer si vous obtenez une erreur de dépendance non satisfaite

— Rj_Innocent_Coder

Vraiment super d'avoir ça. Cela a résolu le problème

— Jerrychayan

J'avais un problème de dépendance. La seule solution que j'ai pu trouver. Merci.
