karma command not found when karma already installed - macos

Question

I used node.js to install karma. My first try failed when running the following command on Terminal:
npm install -g karma
That failed so I decided to use:
sudo npm install -g karma
After entering my password it seemed to install correctly.
I am pasting part of the output of the install, maybe it will mean something to someone and it will be relevant to my question. After all the npm http messages this is what I see:
> ws#0.4.27 install /usr/local/share/npm/lib/node_modules/karma/node_modules/socket.io/node_modules/socket.io-client/node_modules/ws
> (node-gyp rebuild 2> builderror.log) || (exit 0)

Then when I try to run the following command to create a karma config file with this command:
karma init karma.config.js
this is the message that gets returned:
-bash: karma: command not found
I have tried the same command with sudo before it but I get the same result.
Does anyone have any idea as to what is going on?
Any help is appreciated.
*Update!
I decided to check a file named: builderror.log
located in: /usr/local/share/npm/lib/node_modules/karma/node_modules/socket.io/node_modules/socket.io-client/node_modules/ws
This is what it shows:

Answer 1

#mayankcpdixit gave the answer up there in a response to the OP's original question, but I'll put it here again in case anyone misses it.
You do not need to uninstall everything, and if I had to manually add a new path link for every npm package I try to install I'd probably shoot myself.
npm install -g karma-cli
Boom. Now you have karma command lines installed. Just like Grunt.
Edit: Please don't forget to upvote #mayankcpdixit as well, he commented directly on the original post, but didn't actually "answer" the question.

Answer 2

In your ~/.bash_profile (or similar) amend your PATH to include npm-installed binaries:
export PATH="$PATH:/usr/local/share/npm/bin"
I had this very same issue, and found this solution to be less time-consuming and impactful than completely re-installing node.
EDIT this has also worked for others in bash_profile
export PATH="$PATH:/usr/local/lib/node_modules/karma/bin"

Answer 3

It is recommended to install karma with its Command-Line-Interface (karma-cli) which will take care of fetching the appropriate karma. You can also install a different local version specific to each project you're working on and karma-cli will pick the appropriate one.
From the karma installation page:
Typing ./node_modules/karma/bin/karma start sucks so you might find it useful to install karma-cli globally:
npm install -g karma-cli
Now, check that karma was installed by typing:
karma start
You can also check that karma was installed by going to this directory:
cd /usr/local/lib/node_modules/karma
Good luck!

Answer 4

Don't need to completely uninstall node.js
Just
sudo rm -rf /usr/local/lib/node_modules/npm/
Then
install node.js
Then
reinstall karma
This worked for me.

Answer 5

I had to add export PATH="$PATH":/usr/local/lib/node_modules/npm/node_modules/karma/bin after installing karma with sudo npm install karma.
hope this helps.

Answer 6

Just go to test.sh:
Find: $BASE_DIR/../node_modules/karma/bin/karma start $BASE_DIR/../config/karma.conf.js $*
Replace with: /usr/local/bin/karma start $BASE_DIR/../config/karma.conf.js $*
Or: karma start $BASE_DIR/../config/karma.conf.js $*

Answer 7

I was also facing the same issue. It looks like karma for command line is a separate package which can be installed by
npm install -g karma-cli

Answer 8

When upgrading from Karma 0.10 to 0.12 the link to the karma executable is removed.
You can get it back with
cd node_modules/.bin
ln -s ../karma/bin/karma karma

Answer 9

Try re-installing node.js. There are lots of ways to install it, but I recommend downloading from nodejs.org
If that doesn't work, you may try to re-install karma.
