We may face this error if we run npm run dev this. We need to make cross-env working globally instead of having it in the project.

Solution 1

1. Delete node_modules folder from your project.
2. Run npm install --global cross-env this command.
3. Delete "cross-env": "^5.0.1", from package.json file devDependencies section.
4. Run npm install --no-bin-links
5. Now run npm run dev to what happens.

Solution 2

1. Delete node_modules directory from your project.
2. Delete package-lock.json file.
3. Start command prompt as Administrator.
4. Run npm install
5. Then Run npm run dev
