generator-karma does not satisfy its siblings' peerDependencies requirements

Question

The same notorious error

npm ERR! peerinvalid The package generator-karma does not satisfy its siblings' peerDependencies requirements!
npm ERR! peerinvalid Peer [email protected] wants generator-karma@~0.6.0
npm ERR! peerinvalid Peer [email protected] wants generator-karma@~0.5.0

comes from installation various packages, e.g. for

npm update -g yo

The only found advice to uninstall generator-karma does not help - it re-installs back.

Any better explanation of why it happens and working solution?

Just making it clear, you did try sudo npm update -g generator-karma correct? You may also try looking at /node_modules/generator-karma/package.json, and view the version to see if it's above equal or above 0.6.0. – Thermostat

Yes, I tried that too. I was able to get rid of that error by uninstalling generator-angular-ui-router, which seems to use older version of generator-karma. Kind of annoying there is no better way. – Thereof

Answer 1

You need to update all of your globally installed NPM packages. Run this command from your console:

npm update -g

This command will update all the packages listed to the latest version (specified by the tag config).

It will also install missing packages.

When you specify the -g flag, this command will update globally installed packages. If no package name is specified, all packages in the specified location (global or local) will be updated.

Just running this fixed the problem for me – Exceed

This command totally screwed npm for me. It came back with lot of error and now I have this : -bash: /usr/local/bin/npm: No such file or directory. Think twice before running this – Sauder

@Sauder npm has destructive behavior of deleting itself sometimes upon failure. You can simply restore it by re-installing node. Annoying but works. – Thereof

Answer 2

Try running npm uninstall -g generator-karma

Conner

Any explanation what exactly happens here? – Thereof

not really sorry, I just had this generator somehow installed globally and uninstalling it fixed it. I reckon there have been a lot of changes during different versions of karma. – Conner

Good call. I ran into this when trying to install webpack and this solution satisfies it as well. – Toritorie

This worked for me. Thanks! I then re-installed karma afterwards and everything was happy. – Davenport

Answer 3

I had a similar issue and I did this in terminal:

rm -rf /usr/local/lib/node_modules/karma-*

and then updated the package.json:

  "devDependencies": {
    "karma": "0.12.0",
    ...
  }

then reinstall

sudo npm install karma

It worked for me

You should never sudo npm -- see https://mcmap.net/q/503117/-how-to-remove-sudo-requirement-for-local-npm-install – Thereof

Answer 4

It fixed it by running this command, which installs the latest version from GitHub:

$ npm install -g git://github.com/iamblue/generator-angular-ui-router.git

I had tried all the others - for Windows your solution was the only one that worked – Dropsy

Answer 5

i was able to install simply by:

npm install karma-generator

Guess it installs a later version of Karma. I was able to successfully install generator-angular after that. Was able to get coffeescript going as well after doing the above.

Answer 6

I had permissions issues with some of the directories under /usr/local/lib/node_modules. I must have installed some packages with sudo but most under my own user id. I solved this issue on a Mac with these commands:

sudo chown -R `whoami` /usr/local/lib/node_modules/
sudo chgrp -R admin /usr/local/lib/node_modules/
