Knowing that there is Django, there was a tutorial site first, so I tried it. Since I am new to Python, there were many places where I failed, so I made a note to look back. There should be no problem for people who are used to it. Or rather, if you matched the versions of Python and Django on your Mac as per the tutorial, there should have been no problem.

Tutorial site I tried this time

https://djangobrothers.com/ The guy who makes the blog management site of

environment

Windows 10
python 3.8.1
Django 2.0.2

Since it is Python 3.6 in the tutorial, it is better to match it. I got an error because of 3.8.1.

Where I stumbled

Creating a virtual environment
Enter the virtual environment
pip update
Display in the directory
Create an empty file
Error on admin page
I can't post a blog from the admin page

1. Creating a virtual environment

cd /d C:\XXX\
python3 -m venv virtual environment name

I didn't even get an error. In Python3, you can use python, so solve it with the following command.

cd /d C:\XXX\
python -m venv virtual environment name

2. Enter the virtual environment

For Windows

.\Virtual environment name\Scripts\activate

3. pip update

(Virtual environment) >pip install --upgrade pip
...
Installing collected packages: pip
  Found existing installation: pip 19.2.3
    Uninstalling pip-19.2.3:
ERROR: Could not install packages due to an EnvironmentError: [WinError 5]Access denied.: 'xxx\\scripts\\pip.exe'
Consider using the `--user` option or check the permissions.

Adding --user as instructed does not succeed. Probably because it has been uninstalled.

(Virtual environment) >pip install --upgrade pip --user
Traceback (most recent call last):
  File "xxx\AppData\Local\Programs\Python\Python38-32\lib\runpy.py", line 193, in _run_module_as_main
    return _run_code(code, main_globals, None,
  File "xxx\AppData\Local\Programs\Python\Python38-32\lib\runpy.py", line 86, in _run_code
    exec(code, run_globals)
  File "xxx\Scripts\pip.exe\__main__.py", line 5, in <module>
ModuleNotFoundError: No module named 'pip'

You can install pip, but it's easier to initialize the virtual environment

cd /d Directory above the virtual environment#Move to a directory above the virtual environment
python -m venv --clear virtual environment name#Initialization
.\Virtual environment name\Scripts\activate  #Enter the virtual environment
(Virtual environment) >pip install --upgrade pip --user

4. Display in the directory

On Windows, the dir command instead of ls

5. Create an empty file

On Windows

copy nul index.html

6. Error on admin page

http://127.0.0.1:8000/adminページでエラーが出た A server error occurred. Please contact the administrator.

Looking at the command prompt screen

    raise UnknownTimeZoneError(zone)
pytz.exceptions.UnknownTimeZoneError: 'Asia/Tkyo'

I forgot to write o in settings.py

#TIME_ZONE = 'Asia/Tkyo'
TIME_ZONE = 'Asia/Tokyo'

7. I can't post a blog from the admin page

django.db.utils.OperationalError: no such table: main.auth_user__old

Reference page https://kenjimorita.jp/operationalerror-at-adminpostspostadd-no-such-table-main-auth_user__old/ https://stackoverflow.com/questions/53637182/django-no-such-table-main-auth-user-old

keep django version 2.1.5 (the issue addressed in this version) pip install django==2.1.5
Delete the SQLite db
Migrate again python manage.py makemigrations and then python manage.py migrate
Start the server python manage.py runserver

I think it's because SQLite was new because my environment didn't follow the tutorial Django Version:2.0.2 Sqlite3:3.28.0

Resolved by recreating SQLite db with django 2.1.5

pip install django==2.1.5
del db.sqlite3
python manage.py migrate
python manage.py runserver
python manage.py createsuperuser

[PYTHON] I tried Django
