소개

Anaconda에서 조금 고뇨고요 하려고 했을 때, python3.7을 사용하고 싶었습니다만, 어째서나 Navigator로 버젼의 선택을 할 수 없었습니다(아래 그림의 풀다운을 선택할 수 없다)


뭐, 약간의 실험 정도이므로, 거기까지 강한 조건도 없었기 때문에, 그대로 하고 있었습니다만 OpenCV의 인스톨시에 깨졌습니다.

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

  - opencv -> python[version='>=2.7,<2.8.0a0|>=3.5,<3.6.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0']

Your python: python=3.8

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

요컨대 마이너 버전(대응하고 있는 버전도 명기해 주고 있습니다)을 넣어, 라고 하는 것으로 3.7을 넣었습니다.

$ conda install python=3.7

그 위에 다시

$ conda install opencv

에서 일건 낙착.
