Trying to install edge-impulse-cli on Mac OS. Getting npm error

I’m a bit of a node/npm noob. I’m trying to install edge-impulse-cli on Mac OS and I’m getting this:

npm install -g edge-impulse-cli

I already set strict-ssl in npm to false.

This is in preparation for upcoming class on April 1.

Please help! Thank you!

Hi @tjfoth,

I’m not entirely sure why you run into this issue but can try the following:

npm uninstall -g --force edge-impulse-cli
NODE_TLS_REJECT_UNAUTHORIZED=0 npm install -g edge-impulse-cli


My company’s security is getting in the way. I’ll use one of my own computers.
