CalledProcessError when installing diffeqtorch

[Silentmoonlight]

Using
julia version 1.7.2
Python 3.8.0
when I try to install diffeqtorch by using python -c "from diffeqtorch.install import install_and_test; install_and_test()",something is wrong
Test Julia dependencies
Traceback (most recent call last):
File "", line 1, in
File "/home/zjh/anaconda/envs/py38/lib/python3.8/site-packages/diffeqtorch/install.py", line 25, in install_and_test

subprocess.CalledProcessError: Command 'export JULIA_PROJECT=/home/zjh/anaconda/envs/py38/lib/python3.8/site-packages/diffeqtorch/julia; julia -E 'using DifferentialEquations'' returned non-zero exit status 1.

I wonder how can I fix it.
