Can not start composer-cli

I followed the instructions to install the hyperledger tools on Ubuntu 18.04. Due to a permission problem I had to change the node_modules directory.

I can run the tools, except composer-cli (composer-cli: command not found).

Installation log:

$ npm install -g composer-cli@0.20
...

Solution

  • Well, as seen in the log snippet. I think you should try to upgrade the version of npm.
