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?

Answer 1

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.

Answer 2

Try following command:

Step 1 : remove node_modules and files and package-lock.json

Then run following command to install dependencies:

Step 2: $ rm -rf node_modules package-lock.json && npm install && npm start

Finally, run your package by following command:

npm start
