Please help ,Thanks.

Answer 1

It looks like you don't have all the required pieces for npm to work on Windows. Try to do a "npm install --global windows-build-tools" and once this is done, rerun "npm install". For more info, see https://www.npmjs.com/package/windows-build-tools

Answer 2

In my case, I did

$ npm update

This should include fabric-client@1.1.2 (at DateTime.Now = Jun/09/2018)

Answer 3

Fabric client and Fabric CA client packages are needed to run this, which you have to install by "npm install" in the folder, if this operation is unsuccessful, remove the node_modules folder and then reinstall it , you can use "rm -rf node_modules" to remove it.

Answer 4

I had the same problem on mac and I had to re-install the xcode tools

sudo rm -rf $(xcode-select -print-path)
xcode-select --install 

Answer 5

rm package-lock.json
rm -rf node_modules
npm install

That should fix issue and install all packages.
