python - Scrapy 安装在 Ubuntu : pkg_resources. DistributionNotFound: attrs

Question

我按照教程 here 安装了scrapy ，安装成功但是一旦我尝试设置一个项目，它就会显示

pip install Scrapy
nikhil@nikhil:~$ scrapy startproject tutorial
Traceback (most recent call last):
  File "/usr/local/bin/scrapy", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python3/dist-packages/pkg_resources.py", line 2749, in <module>
    working_set = WorkingSet._build_master()
  File "/usr/lib/python3/dist-packages/pkg_resources.py", line 444, in _build_master
    ws.require(__requires__)
  File "/usr/lib/python3/dist-packages/pkg_resources.py", line 725, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3/dist-packages/pkg_resources.py", line 628, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: attrs
nikhil@nikhil:~$ pkg_resources.DistributionNotFound: attrs
pkg_resources.DistributionNotFound:: command not found

关于如何解决这个错误的任何想法..？我无法通过谷歌找到任何有用的指针。
