No binary for PhantomJS browser on your platform. Please, set "PHANTOMJS_BIN" env variable

Question

My package.json looks like this..

"karma-phantomjs-launcher": "^0.1.4",
"karma-safari-launcher": "^0.1.1",
"karma-sinon-chai": "~0.2.0",
"karma-spec-reporter": "~0.0.16",
"mocha": "~1.20.1"

my npm version is 2.2.0

whay am I getting this when I run karma test - karma start my.conf.js

Solution 1

I was having this issue with an older version of node, too. If you don't want to have to hard-code this environment variable, updating your version of node will solve the problem. Just do the following (OSX instructions):

npm uninstall -g phantomjs
npm cache clean -f
brew upgrade nodejs
rm -rf node_modules
npm install -g YOUR_GLOBAL_DEPENDENCIES
npm install

Edit: updated instructions to make sure there is no global phantomjs dependency

Solution 2

This seems to be an issue with phantom js runner and phantom js versions.

https://github.com/karma-runner/karma-phantomjs-launcher/issues/31

How I fixed my issue..

   # install 
   npm install -g karma-phantomjs-launcher

   # temporary path.. set the path
   export PHANTOMJS_BIN=/usr/local/lib/node_modules/karma-phantomjs-launcher/node_modules/phantomjs/lib/phantom/bin/phantomjs

   karma start my.conf.js

Solution 3

I ran into this same problem. The fix is to manually set the PHANTOMJS_BIN variable to point to the correct phantomjs path. Somehow karma launcher tries to look at the wrong path set by PHANTOMJS_BIN.

Here is what worked for me:

$ echo $PHANTOMJS_BIN

/usr/local/lib/node_modules/karma-phantomjs-launcher/node_modules/phantomjs/lib/phantom/bin/phantomjs

$ export PHANTOMJS_BIN=/usr/local/lib/node_modules/phantomjs/lib/phantom/bin/phantomjs

$ grunt test

everything is ok after that.

Solution 4

I remove all my node_modules folder under my Project and run "npm install". This did fix my problem.

Solution 5

I hit this problem with [email protected], where I had also installed [email protected].

Turns out that phantomjs is deprecated, replaced with phantomjs-prebuilt.

Uninstalling both packages and reinstalling phantomjs-prebuilt fixed the problem with karma-phantomjs-launcher:

npm -g remove phantomjs phantomjs-prebuilt
npm -g install phantomjs-prebuilt

The message is pretty clear: there's no PhantomJS installed on your machine. karma-phantomjs-launcher should download a binary of PhantomJS and install on your machine if available: because it's not you have to manually install yourself and then add its path to the environment variables using the PHANTOMJS_BIN.

@MarcoCI I do have the same problem and there actually is a binary of phantomjs being installed together with the karma-phantomjs-launcher.

[MarcoL]

@Flek: then export the path of that file as shown in the answer below.

I fixed it by removing karma-phantomjs-launcher and phantomjs and running npm install

These commands initially seemed to cause more problems then solutions but I eventually worked through them. brew upgrade nodejs didn't work out for me, I got Error: node not installed. But it seems that just unistalling phantomjs, cleaning npm cache, and reinstalling packages with npm cleared my No binary for PhantomJS browser on your platform. Please, set “PHANTOMJS_BIN” env variable error. Thank you!

exactly why i didnt want to embark on them. i physically downgraded node to cure another problem. no time for that tonite

I am able to do this for the first time, but every time I close my system and restart the app, I have to do this again. Is there a way to permanently get rid of this error?

I also ran into issues with npm after doing the upgrade... npm install would simply quit after a deprecation warning. Physically downloading the latest from nodejs.org fixed it for me
