QUESTION

Python/Docker ImportError: cannot import name 'json' from itsdangerous

Asked 2022-Mar-31 at 12:49

I am trying to get a Flask and Docker application to work but when I try and run it using my docker-compose up command in my Visual Studio terminal, it gives me an ImportError called ImportError: cannot import name 'json' from itsdangerous. I have tried to look for possible solutions to this problem but as of right now there are not many on here or anywhere else. The only two solutions I could find are to change the current installation of MarkupSafe and itsdangerous to a higher version: https://serverfault.com/questions/1094062/from-itsdangerous-import-json-as-json-importerror-cannot-import-name-json-fr and another one on GitHub that tells me to essentially change the MarkUpSafe and itsdangerous installation again https://github.com/aws/aws-sam-cli/issues/3661, I have also tried to make a virtual environment named veganetworkscriptenv to install the packages but that has also failed as well. I am currently using Flask 2.0.0 and Docker 5.0.0 and the error occurs on line eight in vegamain.py.

Here is the full ImportError that I get when I try and run the program:

veganetworkscript-backend-1  | Traceback (most recent call last):
veganetworkscript-backend-1  |   File "/app/vegamain.py", line 8, in <module>
veganetworkscript-backend-1  |     from flask import Flask

How exactly can I fix this code? thank you!

ANSWER

I was facing the same issue while running docker containers with flask.

I downgraded Flask to 1.1.4 and markupsafe to 2.0.1 which solved my issue.

Check this for reference.

Install mysql

Simple install the package to your $GOPATH with the go tool from shell:. Make sure Git is installed on your machine and in your system's PATH.

Support

Since version 1.5 Go-MySQL-Driver automatically uses the collation utf8mb4_general_ci by default. Other collations / charsets can be set using the collation DSN parameter. Version 1.0 of the driver recommended adding &charset=utf8 (alias for SET NAMES utf8) to the DSN to enable proper UTF-8 support. This is not necessary anymore. The collation parameter should be preferred to set another collation / charset than the default. See http://dev.mysql.com/doc/refman/8.0/en/charset-unicode.html for more details on MySQL's Unicode support.
