Sqlalchemy IO и операционные ошибки

0 голосов
/ 16 мая 2019

Я использую Ubuntu 18.04 как часть WSL (подсистема Windows для Linux). Версия python 2.7, а версия sqlalchemy 0.7, которая требуется для пакета pele pele, (https://github.com/pele-python/pele). При запуске сценариякоторый вызывает библиотеку pele, я получаю IOError из sqlalchemy.

Когда я делаю то, что предлагает предыдущая ошибка, я получаю ошибку: sqlalchemy.exc.OperationalError: (OperationalError) нет такой таблицы: tbl_minima 'ALTER TABLEtbl_minima ADD fvib FLOAT; '().

The first error is below:

Traceback (most recent call last):
  File "bh.py", line 4, in <module>
    database=system.create_database('lj17.sqlite')
  File "/home/gn203/.local/lib/python2.7/site-
packages/pele/systems/basesystem.py", line 234, in create_database
    db = Database(**kwargs)

    "%d (%d). Please use migrate_db.py in pele/scripts to update database"%(schema, _schema_version))
IOError: database schema outdated, current (newest) version: 0 (2). Please use migrate_db.py``` 

```Second error is below:```

```lj17.sqlite

newest version: 2
