Can you please tell me what does this error mean ?
gapic-google-cloud-logging-v2 0.91.3 has requirement google-gax<0.16dev,>=0.15.7, but you'll have google-gax 0.12.5 which is incompatible.
You have an older version of google-gax.
To update you can run:
npm update -g google-gax
To install the latest version you can run:
npm install google-gax
