Hello Colleen,
Yes, I concur that this is a space issue and changing your $TMPDIR from /tmp is a great idea!
See this post:
# Make new directory
mkdir -p /full/path/to/new/temp
# Export this environment variable:
export TMPDIR='/full/path/to/new/temp'
# and/or check on what it's set to
echo $TMPDIR
Maybe someone else is using up all the space on /tmp
