Error: Cannot find module '../lib/utils/unsupported.js' while using Ionic

Question

I always get this error message when I run \"Ionic start project name\":

Error message

Running command - failed![ERROR] An error occurred while run         


        

Answer 1

On Mac OS X (10.12.6), I resolved this issue by doing the following:

brew uninstall --force node
brew install node

I then got an error complaining that node postinstall failed, and to rerun brew postinstall node

I then got an error:

permission denied @ rb_sysopen /usr/local/lib/node_modules/npm/bin/npx

I resolved that error by:

sudo chown -R $(whoami):admin /usr/local/lib/node_modules

And now I don't get this error any more.

Answer 2

This is a helpful video and blog post about removing node from your computer OS. It is a different method of removal based on how you installed node in the first place (brew vs. binary file downloaded from https://nodejs.org/en/

• if you installed node with Homebrew then brew uninstall node will work. Verify that with running a node -v command in your terminal.

• Otherwise and if you have installed the binary file from nodeJS's websitethen you have to run this command in your terminal: sudo rm -rf /usr/local/{bin/{node,npm},lib/node_modules/npm,lib/node,share/man/*/node.*}. Again, verify that with running a node -v command.

• In both cases, successful removal of node should result in bash not recognizing what node is if it is completely removed

Answer 3

Try to remove /usr/local/lib/node_modules/npm and reinstall node again. This should work.

On MacOS with Homebrew:

sudo rm -rf /usr/local/lib/node_modules/npm
brew reinstall node

Answer 4

As mentioned earlier.

 sudo rm -rf /usr/local/lib/node_modules/npm
 brew uninstall --force node                
 brew install node

Answer 5

Yes you should re-install node:

sudo rm -rf /usr/local/lib/node_modules/npm
 brew uninstall --force node                
 brew install node

Answer 6

I received a similar error and now have it working.

First make sure you have the latest version

brew update

Remove your previous instance of node:

brew uninstall node

Then reinstall the latest version:

brew install node

And then make sure it is symlinked into /usr/local if it isn't already. You would get an error to let you know to complete this step.

brew link --overwrite node 

More details on how to install/upgrade node are also available.
