我是VM的新手，但正在关注这本书 - DKL的Learning Scrapy。它似乎是通过Vagrant和VirtualBox建立一个虚拟环境。我想我已经完成了所有设置 - 安装了ubuntu 12.04.5 LTS的Vagrant和VirtualBox。
然后我使用Cmder.exe（在我的项目文件夹e：... \ Project中）访问Vagrant
λ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Checking if box 'hashicorp/precise64' is up to date...
==> default: Machine already provisioned. Run `vagrant provision` or use the `--provision`
==> default: flag to force provisioning. Provisioners marked to run always will still run.
λ vagrant ssh

你可以试试：
sudo apt-cache search scrapy
找出包名。在新的Ubuntu系统上，包名是python-scrapy，因此：
sudo apt-get install python-scrapy
您可以随时使用pip安装Scrapy：
pip install scrapy
