安装mavlink遇到的问题（future找不到）

从官网下载mavlink（git clone https://github.com/mavlink/mavlink.git)

然后进入mavlink 目录执行 git submodule update --init --recursive 下载全部子模块

在本目录下执行python -m mavgenerate 提示：

$ python -m mavgenerate
Traceback (most recent call last):
  File "/usr/lib/python2.7/runpy.py", line 162, in _run_module_as_main
    "__main__", fname, loader, pkg_name)
  File "/usr/lib/python2.7/runpy.py", line 72, in _run_code
    exec code in run_globals
  File "/home/ev/work/px4/mavlink/mavgenerate.py", line 42, in <module>
    from pymavlink.generator import mavgen
  File "pymavlink/generator/mavgen.py", line 12, in <module>
    from future import standard_library
ImportError: No module named future
ev@Ev-Mayca:~/work/px4/mavlink$ python -m mavgenerate
Traceback (most recent call last):
  File "/usr/lib/python2.7/runpy.py", line 162, in _run_module_as_main

    from pymavlink.generator import mavgen

    from future import standard_library
ImportError: No module named future

提示没有future模块，解决方案如下

1、安装python3

sudo apt-get install python3

2、安装

sudo apt-get install python3-tk

3、安装pip3

wget https://bootstrap.pypa.io/get-pip.py

sudo python3 get-pip.py

4、执行

sudo pip3 install future
5、执行

python3 -m mavgenerate
6、选择xml文件、选择输出文件夹、选择语言，点击确定

xml选择mavlink/message_definitions/v1.0/common.xml

另外个输出文件夹随便选

语言根据需要选择

7、测试

gcc -I ../../new-mavlink/common/ -o mavlink_udp mavlink_udp.c

编译无错误

我是将输出文件放在mavlink文件夹下的new-mavlink文件夹中
