Python 当u+；w未在src上设置，导致pip安装失败；在哪里报告错误？

我正在执行

pip安装。

，其中当前工作目录位于文件系统上。当

pip

尝试复制目录树（包括

.git

中的文件）时，由于

os.setxattr

中的最终故障，它将失败：

$ pip install .

更深入的挖掘表明，错误源于：

Traceback (most recent call last):

…并可通过以下方式复制：

这适用于未设置用户写入位的任何源文件

现在，谁来处理这件事？这是

pip

、

shutil.copytree

、

shutil.copystat

、

setxattr

、

panfs

中的一个bug，还是以上都没有

报告为。另见
