Downgrading is not easy due to the fact that older installers are removed when a new alpha is up. In this guide i am going to show how to downgrade nodejs on windows10.

Why?

Some packages require a specific versions  range of nodejs and npm. for example, version 5 of React-native doesn’t work with npm5.

Steps

  1. Delete the current nodejs version (Or delete the relevant nodejs parameters path from the Environment variables as shown on step 6 and 7).
  2. Visit all the nodejs available versions: 
    https://nodejs.org/dist/
  3. Select the version you need. for this guide, i am selecting 
    v7.9.0/
  4. Select the windows architecture you need. I selected x86: 
    node-v7.9.0-win-x86.zip
  5. Extract the zip file and place it on a permanent folder. for example: 
    ​c:\nodejs-v7.9.0
  6. Update windows variables: Press Start button >Write Environment and then select the next option:

  7. In the poped up window, Select Environment Variables
  8. In the poped up window, Edit the Path parameter under User variables for [username] and under System Variables add the path: 
    ​c:\nodejs-v7.9.0
