This is in a docker container running on MacOSX

node_exporter version: output of node_exporter -version

bash: ./node_exporter: No such file or directory (hence my problem)

Are you running node_exporter in Docker?

Yes. Image Ubuntu:16.04

What did you do that produced an error?

Try to execute node_exporter

What did you expect to see?

It working.

What did you see instead?

bash: ./node_exporter: No such file or directory

I downloaded the linux-386 binaries and unzipped the tarball, which gave me the directory containing the node_exporter executable and LICENSE and NOTICE files. Attempting to execute the node_exporter script yields the warning documented above.
This is the release binary I downloaded: https://github.com/prometheus/node_exporter/releases/download/v0.14.0/node_exporter-0.14.0.linux-386.tar.gz

It looks like the problem is you're trying to run a 32-bit linux binary on a 64-bit platform.

You probably want the amd64 binary.
