Error in bazel build -c opt xls/...

[Sujeet Kamble]

I am a newbie in xls, but while running the command bazel build -c opt xls/... I am getting many errors.
Attached is also a screenshot for the same.

[Leary, Chris]

Hi Sujeet,

"Connection reset" sounds like your network connection was interrupted when dependencies were being downloaded.

Since our CI is passing I imagine this might be a specific problem with your environment.

Can you try again / try with a clean image / make sure your network connectivity seems right? e.g. can you wget the URL?

Also consider installing from conda (as described in the README) if you want to avoid building from source.

Cheers,

- Chris Leary
