Python3.7 system installation raises: ImportError: cannot import name 'SerializableEncoder' from 'mashumaro.types'

[czardien]

Describe the bug

After installation from source guide: https://docs.getdbt.com/dbt-cli/installation#install-from-source, running dbt --help raises:

Traceback (most recent call last):
  File "/home/adrien/.local/bin/dbt", line 11, in <module>
    load_entry_point('dbt-core==0.19.0', 'console_scripts', 'dbt')()

    from dbt.dataclass_schema import dbtClassMixin
  File "/home/adrien/.local/lib/python3.7/site-packages/dbt/dataclass_schema.py", line 13, in <module>
    from mashumaro.types import SerializableEncoder, SerializableType
ImportError: cannot import name 'SerializableEncoder' from 'mashumaro.types' (/home/adrien/.local/lib/python3.7/site-packages/mashumaro/types.py)

Steps To Reproduce

With a python3.7 package, follow installation from source guide at: https://docs.getdbt.com/dbt-cli/installation#install-from-source:

$ cd /tmp
$ git clone https://github.com/fishtown-analytics/dbt
$ cd dbt
$ python3.7 -m ensurepip && python3.7 -m pip install --upgrade pip
$ python3.7 -m pip install -r requirements.txt
$ dbt --help

... should raise the above error.

Expected behavior

dbt --help

... shouldn't raise an error.

Screenshots and log output

The operating system you're using:
Linux host 5.11.2-arch1-1 #1 SMP PREEMPT Fri, 26 Feb 2021 18:26:41 +0000 x86_64 GNU/Linux

The output of python --version: python 3.7.9

Additional context

I'm not using a virtual environment as advised in the docs because I don't mind but I didn't think it would be a problem. From a virtual environment and install dbt directly everything is fine:

$ python3.7 -m venv venv
$ venv/bin/pip install dbt 
$ venv/bin/dbt --version
installed version: 0.19.0
   latest version: 0.19.0

Up to date!

Plugins:
  - bigquery: 0.19.0
  - snowflake: 0.19.0
  - postgres: 0.19.0
  - redshift: 0.19.0

Another point is that I couldn't find the class SerializableEncoder imported at: dataclass_schema.py in mashumaro.types.py, with:

$ python3.7 -m pip show mashumaro
Name: mashumaro
Version: 2.0
Summary: Fast serialization framework on top of dataclasses

Just pointing out that I also get the error from a regular system-wide pip install with python3.7, i.e. not from the source:

$ python3.7 -m ensurepip && python3.7 -m pip install dbt
$ dbt --help
Traceback (most recent call last):

hey @czardien, sorry about this. The develop branch of dbt, which is also set as the default branch, is unstable at the moment and it is unable to be installed from source without also installing the dependencies listed in dev_requirements.txt (pip install -r dev_requirements.txt). We are aware of this and will be resolved once #3138 is merged. (which should hopefully be soon!)

As for #3143 (comment), I believe this is related to the previous attempt to install dbt from source. Please uninstall dbt completely first or pass --force-reinstall (python3.7 -m pip install dbt --force-reinstall) Hope this helps! Closing this issue for now, as #3138 should resolve this.
