Error: spawn nj-cli ENOENT when building ~/.npm-global/lib/node_modules/@fraction/oasis/node_modules/ssb-validate2-rsjs-node

What's the problem you want solved?

When running npm -g install fraction/oasis#semver:on the current stable release of Manjaro-ARM, the build fails with the following:

$ npm -g install fraction/oasis#semver:
npm WARN deprecated debug@4.1.1: Debug versions >=3.2.0 <3.2.7 || >=4 <4.3.1 have a low-severity ReDos regression when used in a Node.js environment. It is recommended you upgrade to 3.2.7 or 4.3.1. (https://github.com/visionmedia/debug/issues/797)

FWIW, this also fails in the same way when building Patchwork, as well as with TOT (npm -g install . when in repository)

I just looked into https://www.npmjs.com/package/ssb-validate2-rsjs-node, which mentions that the package requires rust to be installed and functional:

Rust first needs to be installed in order to build the bindings (installation instructions).

git clone git@github.com:ssb-ngi-pointer/ssb-validate2-rsjs-node.git
cd ssb-validate2-rsjs-node
cargo install nj-cli
# generate release build of ssb-validate2-rsjs-node
npm run build
# run the tests
npm run test

The build process creates bindings in ./dist/index.node.

If you wish to rebuild the bindings after making changes to the code, use the nj-cli tool:

nj-cli build --release

Confirmed: Making sure I had a working Rust and nj-cli as above resolved the issue. Installation documentation needs to be updated
