Cannot find module 'typescript' Error in TS

Cannot find module 'typescript' Error in TS #

To solve the cannot find module 'typescript' error, make sure to install typescript globally by running the npm i -g typescript command and create a symbolic link from the globally-installed package to node_modules by running the npm link typescript command.

Open your terminal in your project's root directory and run the following commands:

Copied!
# ✅ Install TypeScript globally
npm install -g typescript

# ✅ Create a symbolic link from the global package
# to node_modules/ of current folder
npm link typescript

Once you run the two commands, the error should be resolved.

If the global installation of TypeScript fails, you might have to run the command with sudo.

You can check if you have TypeScript installed successfully, by running the following command:

Copied!
tsc --version

The output of the command should show the version of the TypeScript package on your machine, e.g. 4.8.0.

The npm link command creates a symbolic link from the globally installed package to the node_modules/ directory of the current folder.

If the error is not resolved, try to delete your node_modules and package-lock.json files, re-run npm install and restart your IDE.

Copied!
rm -rf node_modules package-lock.json

npm install

npm link typescript

Make sure to restart your IDE if the error persists. VSCode glitches often and a reboot solves things sometimes.

If this also doesn't work, try installing TypeScript locally.

Copied!
npm install --save-dev typescript

This will add typescript to the development dependencies of your project, so you don't have to run the link command.
