我正在尝试使用以下命令安装Scrapy:
$ sudo pip install scrapy
但是在此之后,它显示以下输出并出现错误:

我搜索了任何解决方案,并根据其中一条建议尝试使用以下命令安装python-dev
:
$ sudo apt-get install python-dev
但是这也显示出python-dev
已经是最新版本:
Reading package lists... Done
Building dependency tree
Reading state information... Done
python-dev is already the newest version.
有人能帮我解决这个问题吗?
python3-dev
