Composer Error: git fetch composer" exceeded the timeout of 300 seconds

git fetch composer" exceeded the timeout of 300 seconds

Composer itself impose a limit on how long it would allow for the remote git operation. Composer documentation confirms that the environment variable COMPOSER_PROCESS_TIMEOUT governs this. The variable is set to a default value of 300 (seconds) which is apparently not enough for a large clone operation using a slow internet connection.

We can resolve this problem by raising composer's process timeout value.

#export COMPOSER_PROCESS_TIMEOUT=600

Then re-run the composer commands.
