I get this error when I try to run python

```
(myvenv) C:\Users\SONY\Desktop\djangoproject>python
    Fatal Python error: Py_Initialize: unable to load the file system codec
    ModuleNotFoundError: No module named 'encodings'

I use window 7, it runs without errors in CMD but when I activate the virtualenv it still prints out that error. I had Python 3.6.2 installed previously, I uninstalled it and installed 3.6.7 that's when my problem began.

Note: I created the Virtualenv with 3.6.2

Any ideas on how I can fix this please??
