无法使用虚拟环境在 Windows Ubuntu WSL 中启动 Scrapy 项目

Question

我是 Scrapy 的新手，发现这个错误让我很困惑。我在 Windows 机器上工作，并使用 Ubuntu 子系统 (WSL) 来完成我所有的开发工作。我已经创建了一个虚拟环境并尝试开始学习Scrapy，但是，每当我在虚拟环境中尝试创建一个新项目时，就会出现以下错误并且无法成功创建文件。

OS: Windows 10

环境：Windows10 - WSL Ubuntu20.04.1

Python: Python 3.8.5

重现问题：

python3 -m venv /Directory/
source /Directory/bin/activate
(venv) pip install scrapy
(venv) scrapy startproject /directory/

错误信息：

Traceback (most recent call last):
  File "/mnt/c/Users/.../bin/scrapy", line 10, in <module>
    sys.exit(execute())

    _copyxattr(src, dst, follow_symlinks=follow)

    os.setxattr(dst, name, value, follow_symlinks=follow_symlinks)
PermissionError: [Errno 13] Permission denied: '/mnt/c/Users/.../module/spiders'

奇怪的是，当我不使用虚拟环境时，它工作得很好。有什么办法可以解决这个问题吗？

非常感谢。

Answer 1

而不是

python3 -m venv /Directory/

尝试

python3 -m venv Directory

前者将您的虚拟环境作为目录放在 / 而不是当前目录中。

(请不要调用你的虚拟环境目录;))
