Trying to setup marbles application locally and encountered this error when tried to install the chaincode Steps followed:

1. Cloned the fabric-samples first and installed all the necessary node modules and got the CA Cert for Admin and User and also tested the fabcar sample app with node query.js and got the output properly.
2. Cloned the marbles app from github
3. cd marbles
4. sudo npm install : got the error for Error: EACCES: permission denied on a pkcs11js but fixed it with sudo npm install pkcs11js --unsafe-perm=true --allow-root as mentioned in the fabric-samples setup document.
5. sudo npm install
6. cd ./scripts
7. node install_chaincode.js : got the error

   
   throw err;
   ^

Error: Cannot find module 'fabric-ca-client/lib/FabricCAClientImpl.js' at Function.Module._resolveFilename (module.js:547:15) at Function.Module._load (module.js:474:25) at Module.require (module.js:596:17) at require (internal/module.js:11:18) at module.exports (/Volumes/D Drive/Gitlab/marbles/utils/fc_wrangler/parts/enrollment.js:11:18) at module.exports (/Volumes/D Drive/Gitlab/marbles/utils/fc_wrangler/index.js:10:51) at Object.

but fixed the above error by ```sudo npm install fabric-ca-client```

then again tried node install_chaincode.js but got this error:
