Bump

I'm not sure we want PlayOnMac to be dependant on NodeJS as it is written in Python ; moreover, the default netcat works properly with PoM.

[madprogramer]

I still have no idea why PoM was looking for node, because I had python installed. But

The problem I had was that PoM was misreporting netcat as missing, when it was upset with node. Printing those

env: node: No such file or directory

messages. After re-installing node, PoM found netcat just fine. This fixes the issue on my machine, at least.

[qparis]

Yes, but it enforce every PoM users to have nodejs installed, which should not because PoM is not written in node.
We'd better find a way to understand why POM is not happy with your own netcat

The reporter most likely used https://www.npmjs.com/package/nc, https://github.com/roccomuso/nc or similar, which seems to install by default as /usr/local/bin/nc - just have a look with a text editor what your /usr/local/bin/nc contains.
