LibMambaUnsatisfiableError: Encountered problems while solving: - nothing provides _python_rc needed by python-3.12.0rc3-rc3_h2628c8c_1_cpython Could not solve for environment specs The following packages are incompatible \u251c\u2500 phonopy 2.27.0** is installable and it requires \u2502 \u2514\u2500 python_abi 3.8.* *_cp38, which can be installed; \u2514\u2500 python 3.12** is not installable because there are no viable options \u251c\u2500 python [3.12.0|3.12.1|...|3.12.5] would require \u2502 \u2514\u2500 python_abi 3.12.* *_cp312, which conflicts with any installable versions previously reported; \u2514\u2500 python 3.12.0rc3 would require \u2514\u2500 _python_rc, which does not exist (perhaps a missing channel).
