Hi,all

I want to install dolfinx on anaconda.(I use anaconda on MacOS)  
I tried the following command,

##### 

import gmsh  
import numpy as np  
import pyvista  
import dolfinx

from dolfinx.fem import (Constant, dirichletbc, Function, FunctionSpace, assemble\_scalar,  
form, locate\_dofs\_geometrical, locate\_dofs\_topological)  
from dolfinx.fem.petsc import LinearProblem  
from [dolfinx.io](http://dolfinx.io) import XDMFFile  
from dolfinx.mesh import create\_unit\_square, locate\_entities  
from dolfinx.plot import create\_vtk\_mesh

###### 

But I can`t install dolfinx and following this error appeared. Error:No module named `dolfinx`

###### 

So,I use the command `conda install -c conda-forge fenics-dolfinx` on anaconda.  
But I can`t install dolfinx and appear this message.

###### 

Solving environment: failed with repodata from current\_repodata.json, will retry with next repodata source.

###### 

How can I install dolfinx on anaconda?

thank you in advance for your help!

This worked for me on a mac: [GitHub - FEniCS/dolfinx: Next generation FEniCS problem solving environment](https://github.com/FEniCS/dolfinx#conda)

As these commands work on other people’s mac’s it would be good if you could put the full trace (copy your input commands, and the corresponding output) and put it in markdown format, i.e.
