Expected Behavior:

can re-install

Steps To Reproduce:

1. prepare some directory as deps. I prepared 50 directories.
2. create a new dir(target) and run 'npm init' in it
3. list prepared directory into dependencies
4. run 'npm i' in target
5. run 'npm i' in target again

Environment:

• OS: osx
• Node: 12.8
• npm: 6.14.6

it seems something overflow caused this bug. when I reduce directory count to 9, I can't reproduce this problem
