lxml永远不会在ubuntu上完成构建

Question

我在vwmare上运行ubuntu 14.04 LTS和python 2.7.5.

当我跑:

sudo pip install lxml

我明白了:

Collecting lxml
  Using cached lxml-3.4.4.tar.gz
Building wheels for collected packages: lxml
  Running setup.py bdist_wheel for lxml

永远运行.

我找不到与此相关的任何资源,也没有任何类似错误的经验.

注意,下面的解决方案不起作用:

sudo apt-get build-dep -y lxml;
pip install lxml

我也尝试过:

sudo apt-get install -y build-essential python-dev

我刚刚再次运行它得到了:

sudo pip install lxml

Answer 1

请注意,如果您top在单独的终端中运行,您会注意到您的系统正忙于构建lxml程序包:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1645 root 20 0 322224 305740 5384 R 100.0 29.8 3:27.47 /usr/lib/gcc/arm-linux-gnueabihf/5/cc1 -quiet -I /usr/include/libxml2 -I src/lxml/includes -I /usr/include/python2.7 -imultiarch arm-linux-gnueabihf -D_REENTRANT -D ...

如果你在资源有限的VM或SBC上构建,这可能需要一段时间......

Answer 2

当我尝试在 Raspberry Pi 1 B+ 上“pip install”依赖于 lxml 的包时，我遇到了同样的问题。几个小时（和多次尝试）后，SSH 连接在未完成 Wheel 构建的情况下断开。这似乎是一种内存不足的情况。

我选择分别使用apt install python-lxml或来安装预构建的二进制包apt install python3-lxml。
