Impossibile installare npm - Impossibile correggere i problemi, hai conservato pacchetti rotti?

Sto cercando di aggiornare i miei nodejs a 7.6 ma non sono riuscito. Ora ho un nuovo problema dopo aver reinstallato il nodo 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.

Perché si dice Package 'npm' is not installed, so not removed? sto usando npm per installare molti pacchetti di nodi per i miei progetti !!

Ignoro l'errore e ho continuato l'installazione del nodo 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>

Quindi sono tornato al nodo 6.x. Ma non riesco più a installare 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

prova questo sudo apt install -f, quindi riprova a installare!

— George Udosen,

Ho avuto lo stesso problema con npm e ho dovuto installare i seguenti pacchetti in ordine:

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

Spero che sia di aiuto

Ho lottato con questo per un paio d'ore e questo ha funzionato come un fascino. Grazie!

— desveladisimo,

(Su Kubuntu 18.04) avevo precedentemente installato libssl-dev, che risulta corrispondere a libssl1.1, ma apparentemente npm richiede 1.0. Ho dovuto rimuovere libssl-dev e sostituirlo con libssl1.0-dev, e tutto ha funzionato bene. Gli errori apt non sono stati utili nel determinare ciò che era sbagliato, quindi la tua risposta è stata salvavita.

Sì! Grazie! (Ubuntu 18.04.3 LTS)

Grazie mille, mi aiuta

Ho avuto lo stesso problema con npm.

Ti suggerisco di installare aptitude che può aiutarti a risolvere i conflitti

sudo apt install aptitude

quindi installa il tuo pacchetto con aptitude

sudo aptitude install npm
