Ubuntu 易于获取 NPM 的未满足依赖项

Question

I am trying to install NPM. To do so, I ran:

sudo apt-get install nodejs

This worked successfully. I then ran:

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.
 The following information may help to resolve the situation:

 The following packages have unmet dependencies:
  npm : Depends: node-gyp (>= 0.10.9) but it is not going to be installed
 E: Unable to correct problems, you have held broken packages.

Trying to install node-gyp leads down an endless path of "unmet dependencies".

I followed these instructions and have 0 not upgraded packages; https://askubuntu.com/questions/140246/how-do-i-resolve-unmet-dependencies-after-adding-a-ppa

I disabled all Other Software Source and still have problems. I keep running into this issue for other packages (hhvm and mono). What can I do to resolve these issues?

Answer 1

I exactly had the same symptom and error message when installing npm.

Refer to Node Package Manager got corrupted

You can do the following

sudo apt-get remove nodejs npm ## remove existing nodejs and npm packages
sudo apt-get install curl  
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install -y nodejs  

This works on my Ubuntu 16.04.2

Answer 2

Do sudo apt-get clean or sudo apt-get -f install .

clean clears the local cache of .deb files.

-f means "fix broken".

Answer 3

This happens because the nodejs is already installed in a newer version than the latest ubuntu, possible from a PPA. If you remove the current nodejs and install the one provided by ubuntu, then you can install npm.

You've to remove it with dpkg to avoid remove dependencies:

sudo dpkg -r --force-depends nodejs

Answer 4

On Ubuntu 18.04 I had packages installed that prevented the installation of npm dependencies:

# apt install npm
...
 npm : Hängt ab von: node-gyp (>= 0.10.9) soll aber nicht installiert werden

# apt install node-gyp
...
 node-gyp : Hängt ab von: nodejs-dev soll aber nicht installiert werden

# apt install node-gyp nodejs-dev
...
 nodejs-dev : Hängt ab von: libssl1.0-dev (>= 1.0.2) soll aber nicht installiert werden

# apt install node-gyp nodejs-dev libssl1.0-dev
...
Die folgenden Pakete werden ENTFERNT:
  libcurl4-openssl-dev libneon27-dev libssl-dev

So the problem was that I had these three packages installed:

libcurl4-openssl-dev libneon27-dev libssl-dev

After removing them, I could install npm without problems.

Answer 5

Before running npm install , performing the following steps may help:

remove node_modules using rm -rf node_modules/ run npm cache clean

Answer 6

The error you're getting is because the npm package is tied to the built-in nodejs package.

You do not need to install npm when installing nodejs from nodesource, as it already includes npm .

Just do this:

curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
sudo apt-get install nodejs

It will install both node and npm .

node -v
npm -v
