How to Setup Node.js for WYFA (Write Your First Application) Tests?

✍: FYIcenter.com

A

Before performing any Node.js SDK tests on the WYFA network, you need to setup the Node.js on your local host.

1. Make sure Node.js is installed:

$ node --version
v8.10.0

2. Install required packages:

$ cd hyperledger-binaries/fabric-samples

$ cd fabcar/javascript

$ sudo npm install

> pkcs11js@1.0.17 install /home/fyicenter/hyperledger-binaries/fabric-samples/fabcar/javascript/node_modules/pkcs11js
> node-gyp rebuild

gyp ERR! configure error
gyp ERR! stack Error: EACCES: permission denied, mkdir \
   '/home/fyicenter/hyperledger-binaries/fabric-samples/fabcar/javascript/node_modules/pkcs11js/build'
gyp ERR! System Linux 4.15.0-1037-azure
gyp ERR! command "/usr/bin/node" "/usr/local/lib/node_modules/npm/node_modules/node-gyp/bin/node-gyp.js" "rebuild"
gyp ERR! cwd /home/fyicenter/hyperledger-binaries/fabric-samples/fabcar/javascript/node_modules/pkcs11js
gyp ERR! node -v v8.10.0
gyp ERR! node-gyp -v v3.8.0
gyp ERR! not ok
npm WARN fabcar@1.0.0 No repository field.

Looks like there is a problem with the pkcs11js directory.

3. Create the failed directory manually and try it again:

$ sudo mkdir -p node_modules/pkcs11js/build

$ sudo npm install
...
gyp ERR! configure error
gyp ERR! stack Error: EACCES: permission denied, mkdir \
   '/home/fyicenter/hyperledger-binaries/fabric-samples/fabcar\
   /javascript/node_modules/fabric-client/node_modules/pkcs11js/build'

4. Create the failed directory manually and try it again:

$ sudo mkdir -p node_modules/fabric-client/node_modules/pkcs11js/build

$ sudo npm install
gyp ERR! configure error
gyp ERR! stack Error: EACCES: permission denied, mkdir \
   '/home/fyicenter/hyperledger-binaries/fabric-samples/fabcar\
   /javascript/node_modules/fabric-network/node_modules/pkcs11js/build'

5. Create the failed directory manually and try it again:

$ sudo mkdir -p node_modules/fabric-network/node_modules/pkcs11js/build

$ sudo npm install
gyp ERR! configure error
gyp ERR! stack Error: EACCES: permission denied, mkdir \
   '/home/fyicenter/hyperledger-binaries/fabric-samples/fabcar\
   /javascript/node_modules/fabric-network/node_modules/pkcs11js/build'

It failed again with the same directory. So "npm install" command just deleted the directory and not able to re-create it.

See next tutorial on how to resolve the issue.
