internal/modules/cjs/loader.js:800 throw err

Question

Executed yarn install in my project folder and got below error.

internal/modules/cjs/loader.js:800
throw err;
^
Error: Cannot find module 'ts-node/register'

}

Removed node_module, yarn.lock and node-cache. But no success.

This error is not project specific. If i run yarn, node or npm anywhere in my system I'm getting above error. Is my node and yarn package corrupted?

Solution

Solved Issue by checking NODE_OPTIONS

Run echo %NODE_OPTIONS% and got ts-node/register.

So, to remove ts-node/register run setx NODE_OPTIONS ""

After this node,npm and yarn are working properly.

+1 in my case it was project specific and this fix helped me. my issue occurred after Windows 10 updates on insider build on 3/22/21
