当 python 包安装在本地机器上而不是 virtualenv 中时，如何在 virtualenv 上安装 pytest？

Question

这是我尝试在虚拟环境中为 ONNX 框架安装 pytest 和 nbval 时遇到的错误。我的主目录 (~/) 内存有限。当我尝试使用变量 $IPYTHONDIR 更改 IPython 目录路径时，它表明 pytest 中提到的模块丢失 当我在 virtualenv 中运行测试时，我得到以下结果。

platform linux -- Python 3.7.7, pytest-5.4.1, py-1.8.1, pluggy-0.13.1
rootdir: /local/mnt2/workspace2/Virtual_Env/venv-onnx
plugins: nbval-0.9.5

请清除所有临时文件夹和所有不需要的文件。

您的堆栈跟踪清楚地表明超出了磁盘配额。 磁盘配额是允许您在给定磁盘或位置存储的最大数据量
