Dear all, I am new to using FEniCsx and I am eager to install it using conda. I have a macOs machine. Are there already installation guidelines as for legacy FEniCS? Cheers Philipp ---

Thanks a lot! However, I will still have to install the c++ core and the dependencies before, isn’t it? ---

No, conda should take care of installation of all dependencies. ---

Yes, I had to install “libffi” still via conda install. Now, it works! I guess, one should add it to the conda package, no? ---

The missing cffi dependency should be added on conda-forge shortly: [dolfinx requires cffi by minrk · Pull Request #13 · conda-forge/fenics-dolfinx-feedstock · GitHub](https://github.com/conda-forge/fenics-dolfinx-feedstock/pull/13) It’s also missing [from dolfinx itself](https://github.com/FEniCS/dolfinx/blob/0eab5343fe8674875f94d50706b033d84fa6d67b/python/setup.py#L15-L21). ---

After an update dolfinx does not work properly anymore. It cannot find the JIT module: > File ~/opt/anaconda3/envs/dolfinx/lib/python3.10/site-packages/ffcx/codegeneration/jit.py:78, in get\_cached\_module(module\_name, object\_names, cache\_dir, timeout): > > ModuleNotFoundError: Unable to find JIT module. Is anyone here familiar with that problem? Thanks in advance for your help. ---

Could you try removing `~/.cache/fenics` if that is a folder on your computer. ---
