Question

I am trying to install composer-cli 0.20 but everytime I get this error

I am using VSCode on Windows 10, my node version is 11.6.0 and npm version is 6.5.0. This is what the log file says:

387 verbose npm v6.5.0

Please Help.

Answer 1

Irrespective of the issue you are experiencing, Hyperledger Composer is not supported on windows, nor is node 11 supported on any Hyperledger Composer supported platform, as node 8 is the only supported version of node. I recommend you use a hypervisor such as HyperV, VirtualBox or VMWare to load a supported version of linux for Hyerledger Composer. see https://hyperledger.github.io/composer/latest/installing/installing-prereqs for more information about pre-reqs (note that ubuntu bionic 18.04 although not listed will work as well)

Answer 2

I've been running Composer on Windows 7 with VirtualBox and a few tweaks, so I don't think it is a problem. I think the problem is with the package you're installing. Try creating an empty project and adding sjcl@1.0.7. You can also use a package sniffer and check what's going on during the install.
