J'ai eu la chance d'avoir un Raspberry Pi sous l'arbre cette année et j'ai eu un peu de plaisir à jouer avec Node.js sur l'appareil. Cependant, Node.js est beaucoup plus intéressant lorsque vous pouvez dérouler des packages et les connecter à vos applications - et c'est là que j'ai des problèmes.
Si j'essaie d'installer NPM avec Node.js avec la commande suivante:
sudo apt-get install nodejs npm
J'obtiens l'erreur suivante:
pi@raspberrypi ~ $ sudo apt-get install nodejs npm
Reading package lists... Done

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.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
nodejs : Breaks: npm (< 1.1.4~dfsg-2~) but 1.1.4~dfsg-1 is to be installed
npm : Depends: node-semver but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Je suis assez nouveau sur la façon dont la gestion des packages fonctionne avec les systèmes d'exploitation Linux basés sur Debian et je ne sais pas grand-chose sur la façon dont la communauté node.js a structuré leurs packages spécifiques. Il convient de noter que l'installation de node.js en elle-même fonctionne très bien, et si j'essaie d'installer NPM tout seul, c'est ce que j'obtiens.

Je ne suis pas sûr, mais mon instinct me dit que c'est quelque chose à voir avec le node-semver
paquet. Si j'installe le nodejs
package par lui-même et que j'essaie d'installer node-semver
c'est la sortie que j'obtiens.
