解决办法安装依赖：
```
sudo apt-get install libxml2-dev libxslt1-dev
```
再次安装还有其他错误：
```
ERROR: b'/bin/sh: 1: xslt-config: not found\n'
** make sure the development packages of libxml2 and libxslt are installed **
```
查了一下，这是python-dev中提供的一个头文件，所以需要安装python-dev（我用的是Python3,所以装了python3-dev）。用apt安装一下，然后再用pip install lxml，没想到依旧报错不能安装orz。这次错误换了一个

```
/usr/bin/ld: cannot find -lz
```
stackoverflow上对于这个问题提供的方法是安装zlib1g-dev，用apt-get安装后，再次尝试编装lxml，终于编译安装成功。

实际上用一条命令吧所需的几个dev包装上就能搞定了。
```
sudo apt-get install python-dev python3-dev libxml2-dev libxslt1-dev zlib1g-dev
```
后来发现Stackoverflow上的已经有人问了这个问题。[Stackoverflow](https://stackoverflow.com/questions/5178416/libxml-install-error-using-pip "Stackoverflow链接")

# 安装python-ldap问题
问题：
```inux-x86_64-3.6/Modules/LDAPObject.o
  Modules/LDAPObject.c:16:10: fatal error: sasl/sasl.h: 没有那个文件或目录
   #include <sasl/sasl.h>
            ^~~~~~~~~~~~~
  compilation terminated.
  error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
  ----------------------------------------
  ERROR: Failed building wheel for python-ldap

```
还是缺少依赖
解决办法：
```
sudo apt-get install libsasl2-dev
```
# 总结
安装第三方包过程中有`xml`和`python-ldap`两个包需要分别安装额外的应用：

```
sudo apt-get install python-dev python3-dev libxml2-dev libxslt1-dev zlib1g-dev
sudo apt-get install libsasl2-dev
```
