I want to use conda to install it:
conda create -n fenicsx-env
conda activate fenicsx-env
conda install -c conda-forge fenics-dolfinx mpich pyvista
when I run conda install -c conda-forge fenics-dolfinx mpich pyvista in pycharm, it issues an error that is
Collecting package metadata (current_repodata.json): failed
CondaSSLError: Encountered an SSL error. Most likely a certificate verification issue.
Exception: HTTPSConnectionPool(host='conda.anaconda.org', port=443): Max retries exceeded with url: /conda-forge/noarch/current_repodata.json (Caused by SSLError(SSLEOFError(8, '[S
SL: UNEXPECTED_EOF_WHILE_READING] EOF occurred in violation of protocol (_ssl.c:1006)')))
I don’t know where is wrong, I have run the first 2 commands
That seems like a temporary problem with the certificate. Have you tried again later on? Are you behind a proxy or something similar? If you visit conda.anaconda.org on your web browser can you see it?
I disconnect my vpn then I can install it in the first step, then I encountered PackagesNotFoundError: The following packages are not available from current channels:
Current channels:
what should I do
What operating system are you on?
May be these DL links to these two packages are blocked in China, I am using win10
We don’t have windows package, and no ETA on when they will be available.
Please go to GitHub - FEniCS/dolfinx: Next generation FEniCS problem solving environment, search for
Windows: docker, or install WSL2 and use Ubuntu.
and follow the instructions there.
You can use the TsingHua channel. And I you want to install it in windows, you should use WSL.
(你可以使用清华的镜像，另外在windows上安装（安装在WSL中）记得把安装目录设置成大小写无关的。我在b站写了个教程有限元软件FENICS的安装 - 哔哩哔哩)
