When I try to use pip install to install sage-numerical-backends-gurobi, I encounter the following error:
Error compiling Cython file: ------------------------------------------------------------ ... # the Free Software Foundation, either version 2 of the License, or # (at your option) any later version. # https://www.gnu.org/licenses/ #***************************************************************************** from sage.numerical.backends.generic_backend cimport GenericBackend ^ ------------------------------------------------------------ sage_numerical_backends_coin/coin_backend.pxd::0: 'sage/numerical/backends/generic_backend.pxd' not found. I'm certain that sage.numerical.backends.generic_backend is present in the package. When installing sage-numerical-backends-coin, I encountered the same issue. How can I resolve this? -- You received this message because you are subscribed to the Google Groups "sage-support" group.
