Hyperledger Fabric Fabcar error for enrolladmin.js

Question

I have started the fabric script and after that I run the enrolladmin.js file.

node enrolladmin.js

but got the following error. How to resolve it?

node enrollAdmin.js
fs.js:904
return binding.readdir(pathModule._makeLong(path), options.encoding);
             ^

Answer 1

I had the same problem. just resolved it by these steps:

1. Create directory : < FABCAR_DIR>/node_modules/grpc/src/node/extension_binary/
2. Do "npm install" in < FABCAR_DIR>
3. Do "npm rebuild" in < FABCAR_DIR>

step 2 or 3 - one of them should solve the problem - try in the same order.

After step 2 OR step 3 - you should see a file. < FABCAR_DIR>/node_modules/grpc/src/node/extension_binary/node-v46-linux-x64-glibc/grpc_node.node

After that enroll admin should succeed like:

sprint @ fabcar>node enrollAdmin.js
 Store path:/home/ravir/hl/fabric-samples/fabcar/hfc-key-store
Successfully enrolled admin user "admin"
Assigned the admin user to the fabric client ::{"name":"admin","mspid":"Org1MSP","roles":null,"affiliation":"","enrollmentSecret":"","enrollment":{"signingIdentity":"42d8536072cf7e47358c137b254d78d8e853934caee70d03dbec06a22f482ad9","identity":{"certificate":"-----BEGIN CERTIFICATE-----\}

if u look closely, the output of startFabric.sh prints

"

Start by installing required packages run 'npm install'
Then run 'node enrollAdmin.js', then 'node registerUser'
