当我在根文件夹中为一个项目创建环境时出现 pip 子进程错误

Question

在 Win10 上运行 Ubuntu 18.04 LTS 作为 WSL2，我需要创建一个环境来在我的系统上安装 Devito。因此，在该项目的根文件夹中，我执行：

(base) quant@NB-W-I-NIKONENKO:~/devito$ conda env create -f environment-dev.yml

并得到：

CondaEnvException: Pip failed

下一个安装命令应该是：

source activate devito

有效，下一个：

pip install -e .

显示以下内容：

因此，我无法正确安装包并执行最终命令：

conda update - all –yes

我注意到基本Python版本是3.7.6，源激活后Python版本是3.9.7（我不确定它是否有帮助，但我真的很努力解决这个问题）。
