First look, after installing odoo, such an error will be reported
Solution:
Under python\Lib\_strptime.py, add the code:
locale.setlocale(locale.LC_ALL,'en')
Find _strptime.py
This is generally under the python path, I installed the python virtual environment here, so find the Lib folder under the virtual environment location
Then find _strptime.py
Then under the import header file, add content:
Restart odoo
