Installing express generator error

Question

Everytime I try to run the command npm install -g express-generator I receive the following errors. Do you have a solution to this problem?

Answer 1

Though Your Problem seems to your system's error because as your screen shot shows : I've observed following:

1. You've Altered Your NodeJs Installation Directory(knowingly / Unknowingly)
2. Packages are stored here : "C:\\Users\\YOUR_AC_NAME\\AppData\\Roaming\\npm"

Remedies :

1. First Uninstall Node.js Completely From System
2. Delete Residue Folders left behind
3. Install a Fresh copy of Node.js

4. Add Path to Environment + System Variable as Following :

   C:\\Program Files\\nodejs

   C:\\Users\\YOUR_AC_NAME\\AppData\\Roaming\\npm

5. After That Install Express Generator Globally

Hope It Helps :)
