ReferenceError: window is not defined (moment-duration-format)

[pdcastro]

A dependency of the balena CLI, moment-duration-format was udpated from v2.2.2 to v2.3.0 and this is causing the CLI to break. I've first noticed it during the CLI builds:

C:\Users\Administrator\concourse\work\volumes\live\52cab583-cff9-4400-44e1-0e7b3683d1d4\volume\node_modules\moment-duration-format\lib\moment-duration-format.js:1723
        if (window.Intl && window.Intl.NumberFormat) {
        ^
ReferenceError: window is not defined
...

I've also opened an issue in their repo: jsmreese/moment-duration-format#131

Affects fresh npm installations of balena CLI version 10.17.4 and "all others before that".
I believe it does not affect installations with the standalone zip file.

Anyone affected may also need to delete the .fast-boot.json file from the balena-cli's folder and/or the ./bin/ subfolder (i.e. ./bin/.fast-boot.json subfolder). Otherwise, the CLI may fail with an unhelpful error message:

$ ./bin/balena version
null

Btw, @shaunmulligan, @thgreasi, that's a downside I have noticed with the .fast-boot.json file: when I switch branches I got in habit of deleting the .fast-boot.json file to avoid those null errors. But so far I am not aware of users reporting this error, I've only noticed it myself.

... causing the CLI to break ...

And the API usage of moment-duration-format. Thanks for reporting this upstream as we just encountered this in a different project not too long ago. :) *watching that issue*

@Martii this should now be resolved in CLI version 10.17.5 and later (PR #1282).
Can you try updating your balena-cli installation and give us a note if that's still an issue for you?
