ResolvePackageNotFound and UnsatisfiableError

[wngmng]

When I run "conda env create -f environment.yml", I received a Error:
ResolvePackageNotFound:

• libtiff==4.0.10=h648cc4a_1001
• openblas==0.3.6=h6e990d7_1
  So I deleted these two lines in file "environment.yml", and rerun the command above. Then I got another Error:
  UnsatisfiableError: The following specifications were found to be in conflict:
• liblapack==3.8.0=8_openblas -> libblas==3.8.0=8_openblas -> openblas[version='>=0.3.6,<0.3.7.0a0'] -> libopenblas==0.3.6=h6e990d7_3
• libopenblas==0.3.3=h5a2b251_3
  I changed their version numbers after that, but these Issues did not seem to work out.
