在 anaconda 环境中安装 MySQL Python 包时出现以下错误

Question

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

Specifications:

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

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.

The following specifications were found to be incompatible with each other:

Answer 1

包 mysql-python 仅适用于 Python 2.7，您不需要它和 mysql-connector-python。只需安装后者。
