hi there, you need to check you meet all the pre-reqs here -> hyperledger.github.io/composer/latest/installing/… - You're using Node 10 and it is not supported by Hyperledger Composer - check the docs for the exact Node editions supported and use nvm to install a supported Node version – Paul O'Mahony
The answer was deleted and I can't point you to the other stackoverflow because the top answer is not a good solution to the problem. So what you need to do in a command window is 1) nvm install 8. 2) nvm use 8. Now you can install composer again. The reason is that node 10 has gone LTS and the prereqs-ubuntu script installs the lts version which means node 10 is currently being installed – david_k

You are using node js version 10.x.x, which is not supported by Hyperledger.

Please install node js version 8.x.x.

It will solve your problem.

Note: Make sure that you are installing composer tools as non-root user. Install composer tools without sudo.
