Error findup-sync not found with grunt-cli 0.1.13

We have been working with grunt-cli version 0.1.13 , node version - 6.17.1, npm version-3.10.10
While running grunt commands we are seeing dependency not found errors even though these modules are present in node_modules.
Can anyone help us resolving this issue ?
Error while running grunt --help
Cannot find module 'findup-sync'

Reproduce the failure with grunt --help using grunt-cli 0.1.13, then inspect the reported grunt-cli/bin/grunt entry point and its findup-sync dependency resolution. Done means the command no longer reports “Cannot find module 'findup-sync'” in the stated Node and npm environment.
