Issues installing fabric-sdk-rest

I am trying to install hyperledger fabric sdk rest server. I have cloned fabric-sdk-rest repo and installed the prerequisites but when trying to run "npm link" in packages/loopback-connector-fabric I get the following error:

npm ERR! path /usr/lib/node_modules/loopback-connector-fabric
npm ERR! code EACCES
npm ERR! errno -13
npm ERR! syscall unlink
npm ERR! Error: EACCES: permission denied, unlink '/usr/lib/node_modules/loopback-connector-fabric'
npm ERR!  { Error: EACCES: permission denied, unlink '/usr/lib/node_modules/loopback-connector-fabric'
npm ERR!   stack: 'Error: EACCES: permission denied, unlink \'/usr/lib/node_modules/loopback-connector-fabric\'',
npm ERR!   errno: -13,
npm ERR!   code: 'EACCES',
npm ERR!   syscall: 'unlink',
npm ERR!   path: '/usr/lib/node_modules/loopback-connector-fabric' }
npm ERR! 
npm ERR! Please try running this command again as root/Administrator.

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/user/.npm/_logs/2018-02-12T22_24_45_379Z-debug.log

This is what happens if I run it with sudo:

> [email protected] install /home/user/Documents/fabric-sdk-rest/packages/loopback-connector-fabric/node_modules/pkcs11js
> node-gyp rebuild

gyp ERR! configure error 
gyp ERR! stack Error: EACCES: permission denied, mkdir '/home/user/Documents/fabric-sdk-rest/packages/loopback-connector-fabric/node_modules/pkcs11js/build'
gyp ERR! System Linux 4.8.0-36-generic
gyp ERR! command "/usr/bin/node" "/usr/lib/node_modules/npm/node_modules/node-gyp/bin/node-gyp.js" "rebuild"
gyp ERR! cwd /home/user/Documents/fabric-sdk-rest/packages/loopback-connector-fabric/node_modules/pkcs11js
gyp ERR! node -v v9.5.0
gyp ERR! node-gyp -v v3.6.2
gyp ERR! not ok 
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] install: `node-gyp rebuild`
npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the [email protected] install script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/user/.npm/_logs/2018-02-12T22_26_40_864Z-debug.log

This is done in Ubuntu 16.04. What am I doing wrong?

I was facing this errors too. After a while trying all kind of insane things to get it running I came into account that the problem was I was installing npm modules as superuser globally. This conflicts with hyperledger*.

Solutions is $: sudo npm uninstall -g *** for every module you just installed as superuser.

Then you need to install the modules not as superuser. This are some advices. If installing Hyperledger Composer using Linux, be aware of the following advice:

  • Login as a normal user, rather than root.
  • Do not su to root.
  • When installing prerequisites, use curl, then unzip using sudo.
  • Run prereqs-ubuntu.sh as a normal user. It may prompt for root password as some of it's actions are required to be run as
  • Do not use npm with sudo or su to root to use it.
  • Avoid by all means installing node modules globally as root.

If you're running on Ubuntu, you can download the prerequisites using the following commands:

curl -O https://hyperledger.github.io/composer/prereqs-ubuntu.sh
chmod u+x prereqs-ubuntu.sh

Next run the script - as this briefly uses sudo during its execution, you will be prompted for your password.

$: ./prereqs-ubuntu.sh

This is the best way

Or you can visit this page and follow the prereqs installation guide.

Prerequisites for Ubuntu

and finally follow this link to continue the installation it works just fine.

Install development tools

This is the latest update

Hope this helps
