python - 为什么我安装不了python-Scrapy？

Question

我是 Vagrant 的新手，有一个 trusty64 盒子。我这样做:

sudo apt-get install -y python-pip
sudo pip install --upgrade setuptools

Then this happens.

Traceback (most recent call last):
  File "/usr/local/bin/scrapy", line 7, in <module>
    from scrapy.cmdline import execute
  File "/usr/local/lib/python2.7/dist-packages/scrapy/__init__.py", line 34, in <module>
    from scrapy.spiders import Spider
  File "/usr/local/lib/python2.7/dist-packages/scrapy/spiders/__init__.py", line 10, in <module>
    from scrapy.http import Request
  File "/usr/local/lib/python2.7/dist-packages/scrapy/http/__init__.py", line 11, in <module>
    from scrapy.http.request.form import FormRequest
  File "/usr/local/lib/python2.7/dist-packages/scrapy/http/request/form.py", line 11, in <module>
    import lxml.html
ImportError: No module named lxml.html`

我到底要在这里做什么？首先，我尝试通过 pip3 安装，但后来读到 Twisted 在 2 中。我该如何正确安装？

更新:::@Paula:所以我用

销毁并初始化了它

sudo apt-get install -y python-dev libxml2-dev libxslt1-dev zlib1g-dev python-pip
sudo pip install --upgrade setuptools
sudo pip install Scrapy

在安装 SCRAPY 时，我不止一次打印了这个:

x86_64-linux-gnu-gcc: internal compiler error: Killed (program cc1)
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.8/README.Bugs> for instructions.
Compile failed: command 'x86_64-linux-gnu-gcc' failed with exit status 4

那怎么样？

您需要先运行它。

sudo apt-get install python-dev libxml2-dev libxslt1-dev zlib1g-dev

正如@Cfreak 所说，您有未满足的库依赖项。
