sudo. How do I fix?

# Develop a Knowledge Object
# 🌌 I am having problem with
npm install, failing with
node-gyp. What could be wrong?
One possibility is that your project has dependencies on some native add-on node modules which in turn require Python27 to build on the fly. Install Python27 and try again.
# 🌌 I changed the payload code and rebuilt the KO. However, the KO Service is still using the old code. How to fix that?
auto-reload feature is not turned on for the activator, you will need to manually re-activate the updated KO so that the KO service can be refreshed. To do so, call the
/activate of the activator. Please refer to the KGRID API documentation for details.
# KGrid API
# 🌌 How can I upload multiple Knowledge Objects?
You can create a manifest file containing a list of urls pointing to the artifacts. These KOs should be packaged in ZIP format and retrievable from the host. You can then
POST your manifest
/kos/manifest. For details, please refer to the KGRID API documentation.
