2.& Baidu一下看看问题如何解决：
&&& 原来这个问题，还是需要区分操作系统来分别处理的。window下暂无涉及。
3.& Linux系统的处理方式：
sudo apt-get install python-dev libxml2-dev libxslt1-dev zlib1g-dev&& or yum install .....
&& 然后继续使用 pip install lxml

缺少python包，下载2.7版本
设置系统环境变量
PYTHONPATH=C:\Pyhon
PYTHON=%PYTHONPATH%\python.exe
然后又报错
在此解决方案中一次生成一个项目。若要启用并行生成，请添加“/m”开关。

安装canvas包出错，解决办法：
最近项目需要用到 node-canvas 这个图形模块, 但是在Windows下其安装颇费周折, 经过一天试探,终于搞定了,
下面分享给大家:
1.先安装 P 通过Python 官网
下载并安装最新版本. 然后将Python
的安装目录(如: C:\Program Files\Python) 添加到PATH环境变量中;
2.安装node-gyp 或将 npm 升级到内含 node-gyp 的版本 (nodejs v0.6.13以上的 npm
已内置了node-gyp, 则此步可以略过);
3.再安装 Visual C++ 2010 E 因为需要用到其中的MSBuild 用以编译 cairo 类库到本地代码;
微软官方获取:
(VC++下载和安装的过程很漫长,需要耐心等待);
4.还要下载包含 cairo 图形处理库的GTK包:
选gtk+-bundle_2.24.10-_win32 （注意是整个包）或最新版,
5.将下载的GTK包解压到 C:\GTK\ 目录(必须是这个目录名,否则接下来的MSBuild编译可能通不过),
6.在Windows环境变量PATH 后添加 C:\GTK\bin 目录 (需要注销Windows重新登录才能全局生效), 以供
canvas 运行时调用cairo的动态链接库 libcairo-2.dll 等;
7.最后 npm install canvas , 期间将自动运行MsBuild 编译生成 canvas.node
本地目标库,
生成的目标库位于 path\to\node_modules\canvas\build\Release\canvas.
8.DOS命令行下: CD 进入 canvas\build\Release\ 这个目录, 运行 node
测试canvas是否安装成功:
C:\path\to\node\node_modules\canvas\build\Release& node.exe
var canvas = require('./canvas');
若显示 undefined , 而不是错误信息 ,应该就安装成功了.
若显示Unable to load shared library 则可能是 GTK\bin
目录未在PATH路径中,添加上即可.
