[SolverProblemError]
The current project's Python requirement (*) is not compatible with some of the required packages Python requirement:
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0
  - isort requires Python >=3.6,<4.0

Because no versions of isort match >5,<5.0.1 || >5.0.1,<5.0.2 || >5.0.2,<5.0.3 || >5.0.3,<5.0.4 || >5.0.4,<5.0.5 || >5.0.5,<5.0.6 || >5.0.6,<5.0.7 || >5.0.7,<5.0.8 || >5.0.8,<5.0.9 || >5.0.9,<5.1.0 || >5.1.0,<5.1.1 || >5.1.1,<5.1.2 || >5.1.2,<5.1.3 || >5.1.3,<5.1.4 || >5.1.4,<5.2.0 || >5.2.0,<5.2.1 || >5.2.1,<5.2.2 || >5.2.2
 and isort (5.0.1) requires Python >=3.6,<4.0, isort is forbidden.
And because isort (5.0.2) requires Python >=3.6,<4.0, isort is forbidden.
And because isort (5.0.3) requires Python >=3.6,<4.0
 and isort (5.0.4) requires Python >=3.6,<4.0, isort is forbidden.
And because isort (5.0.5) requires Python >=3.6,<4.0
 and isort (5.0.6) requires Python >=3.6,<4.0, isort is forbidden.
And because isort (5.0.7) requires Python >=3.6,<4.0
 and isort (5.0.8) requires Python >=3.6,<4.0, isort is forbidden.
And because isort (5.0.9) requires Python >=3.6,<4.0
 and isort (5.1.0) requires Python >=3.6,<4.0, isort is forbidden.
And because isort (5.1.1) requires Python >=3.6,<4.0
 and isort (5.1.2) requires Python >=3.6,<4.0, isort is forbidden.
And because isort (5.1.3) requires Python >=3.6,<4.0
 and isort (5.1.4) requires Python >=3.6,<4.0, isort is forbidden.
And because isort (5.2.0) requires Python >=3.6,<4.0
 and isort (5.2.1) requires Python >=3.6,<4.0, isort is forbidden.
So, because isort (5.2.2) requires Python >=3.6,<4.0
 and dummy depends on isort (>5), version solving failed.
