python - 出现错误为什么要在开发模式下尝试 dffml？

Question

这些是我在文档中提到的正在运行的命令

git clone https://github.com/intel/dffml
cd dffml
python3 -m pip install -U pip setuptools wheel
python3 -m pip install --prefix=~/.local -e .[dev]

但是我在最后一个命令上收到警告和错误
警告

WARNING: Ignoring invalid distribution -jango (/home/dhruv/.local/lib/python3.8/site-packages)

错误

    Found existing installation: Pillow 7.0.0
    Uninstalling Pillow-7.0.0:
ERROR: Could not install packages due to an OSError: [Errno 13] Permission denied: '_imagingtk.cpython-38-x86_64-linux-gnu.so'
Consider using the `--user` option or check the permissions.

并且程序在错误后停止执行，我不知道错误的根源是什么以及如何删除它，感谢任何帮助

对于错误，请尝试使用 --user ， 像这样:

python3 -m pip install --user -e .[dev]

Their docs谈谈他们为什么不使用 --user ，但解释对我来说没有多大意义。

Installing to your home directory will reduce permissions issues. To do this we use the --prefix=~/.local flag. pip sometimes gets confused about the --user flag (and will blow up in your face if you try to pass it). So we use the --prefix=~/.local flag, which has the same effect but should always work.

具体来说，不知道为什么 pip会“感到困惑”，但我不是专家。
