Q: Error when installing "node-red-contrib-composer" using "Manage Palette" feature

When I try to install the plugin using the "Manage Palette" feature of node-red the installation fails with a general error: "Error: stderr maxBuffer exceeded". The work-around for me was to install the plugin from the command line inside the .node-red user settings directory.

Note beyond, I am able to install other plugins via "Manage Palette" without problems. So, I don't think it is a general issue with my setup or the way I am using node-red.

So I am wondering, if I am missing something or this is a bug?

Here is how to reproduce the issue:

  • Install hyperledger composer and fabric as described in the development guide - I am using Ubuntu LTS 16.04.3 (64-bit) and Node.js 8.9.1
  • Allow unprivileged users for installing global npm packages (this one is missing in the development guide, btw!) - I used npm-g_nosudo for the setup
  • Install node-red - Execute npm install -g node-red as unprivileged user (no need for --unsafe-perm at this point)
  • Start node-red - Execute node-red on the command line with the user account used to run hyperledger composer and fabric
  • Try to install the node-red-contrib-composerplugin using "Manage Palette"
Solution

  • This is a known issue, see https://github.com/hyperledger/composer/issues/2793

    and is due to this issue in node-red https://github.com/node-red/node-red/issues/1488
