Hi All

I was curious to try out Nanos and started here https://nanos.org/getting_started While ops downloaded fine, when running the ops pkg load command i am running into following issue:

~/code/nanos % ops pkg load node_v14.2.0 -p 8083 -n -a hi.js
panic: runtime error: index out of range [-1]

@chitreshd those instructions need to be updated as we recently namespaced packages under usernames - the correct syntax would now be:

 ops pkg load eyberg/node:v14.2.0 -p 8083 -a hi.js

Had the same issue, just a fyi that it is still "ops pkg load node_v11.5.0 -p 8083 -f -n -a hi.js" on the readme.

@karoofish thanks for the heads up, https://github.com/nanovms/ops/pull/1325
