Error findup-sync not found with grunt-cli 0.1.13

[ManasaVTR]

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 ?

@ManasaVTR, your node js version seems very old

node version - 6.17.1 is that right?

LTS is now at version 18

Yes . We haven't updated node version because few of the dependencies might break .
Do you think updating node version can resolve the issue with grunct-cli ?
