The annoying 'Network error while fetching' while bundle install

Question

I'm trying to install the newest version of gitlab. When I try

sudo -u git -H bundle install --deployment --without development test mysql was --verbose

It always shows an error Network error while fetching, and re-fetches all the packages again when I retry, then the error appears again because my network is not stable. How to tell the bundler not to fetch packages already fetched?

Answer 1

Try adding the bundle install --retry option:

sudo -u git -H bundle install --retry 4 --deployment --without development test mysql was --verbose

This will retry failed network requests 4 times. From the Bundler Documentation:

--retry: Retry network and git requests that have failed.

Note: if it complains about Unknown switches '--retry', then your bundler version is very old. update it with:

gem update bundler

and then try again.
