我得到这个错误：IOError: [Errno 2] No such file or directory: '/usr/local/lib/python2.7/dist-packages/scrapy/core/downloader/responsetypes/mime.types'而且这个位置确实不存在但是这个库在 usr 位置中安装（我通过 pip 安装）：/usr/local/scrapy/core/downloader/responsetypes/mime.types我怎样才能更改 python 配置以便 python 2.7 能够找到他的包（我没有使用 venv）另外我还有另一台电脑可以比较，在我看来主要的区别在于 python 包的位置 - 需要be Location: /usr/local/lib/python2.7/dist-packages但是/home/ubuntu/.local/lib/python2.7/site-packages我怎样才能更改这个前缀？

答案1
Scrapy Python 网络抓取和爬取框架（Python 3）由 Ubuntu 18.04 及更高版本的默认 Ubuntu 存储库提供。要安装它，请打开终端并输入：
sudo apt install python3-scrapy
如果以这种方式安装 Scrapy，Ubuntu 将不会遇到任何找不到它的问题。Ubuntu 18.04 及更高版本中默认未安装 Python 2.x，因此如果您在 Ubuntu 18.04 及更高版本中安装 python3-scrapy，您将更容易使用它。
