What's your version of node and python?

Please make sure you have node 8, python 3.6 or above.

@zixia Node V9.8.0 and Python V3.6.5, but python3 is not recognized here

What's the output when you run the check version helper script?

[leo-def]

I got the following error

[: !=: unary operator expected

in this line

ret=$(node -e 'console.log(process.versions.node.split(".")[0] >= 7 ? 0 : 1)')

But it works's fine when I execute directly in the CMD the following command

node -e 'console.log(process.versions.node.split(\".\")[0] >= 7 ? 0 : 1)

Other problem is about the python3 command that my system can't recognize, I guess that I need to downgrade my python to 3.5.

When I run the following command, its works fine.

python3 -c 'import sys; v = sys.version_info; print("%i" % (v.major <3 or v.major==3 and v.minor<5));'

Can you provide the re-produce steps in detail?

I'm afraid that I could not be able to help without that information.

And I just get the code from latest master branch passed the CI unit tests, you can have a look at https://travis-ci.com/zixia/node-facenet/jobs/124931260, hope it helps.
