Error: Cannot find module './api' (Hyperledger composer)

Question

After installing Hyperledger Composer cli from this page, I tried to call composer command but got this error:

module.js:549
throw err;
^

Error: Cannot find module './api'

I used this command to install Hyperledger Composer:

npm install --unsafe-perm -g composer-cli

May I know what is going wrong?

Answer 1

In my case I installed composer-cli in global /usr/lib/node_modules/composer-cli and I met the same problem. I don't know what's wrong but I tried:

1. Change directory into the composer-cli:

   cd /usr/lib/node_modules/composer-cli

2. Reinstall node report module, locally inside the composer-cli:

   sudo npm install node-report --unsafe-perm

Notice I don't put -g param in sudo npm install to make the installation local to the composer-cli itself.

The node-report will run make with g++ to compile something (which for some reason was not run during composer-cli installation) and it just works... Now I can run composer.

For your case set the working directory to /home/user/.nvm/versions/node/v8.11.1/lib/node_modules/composer-cli instead.
