I could not install node-rdkafka module without setting PYTHON to v2.7. My current version of python is 3.7.1

@cclauss one for you I think? I can't see anything in https://github.com/Blizzard/node-rdkafka/blob/master/binding.gyp that suggests unicode is getting involved, other than the BUILD_LIBRDKAFKA environment variable possibly but it's only used to check for ==1. I also don't see any unicode in the paths here. 🤷‍♂

I believe that @dothebart nailed this one in #1925 which landed in v5.0.6.
v5.0.5 does not have this fix so I believe that npm/cli needs to do another gyp round trip.

[dothebart]

yes, this stacktrace sounds familliar.

[sadvazha]

Yep, works for me after updating npm
