安裝mavlink遇到的問題（future找不到）

從官網下載mavlink（git clone https://github.com/mavlink/mavlink.git)

然后進入mavlink 目錄執行 git submodule update --init --recursive 下載全部子模塊

在本目錄下執行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 future import standard_library
ImportError: No module named future

提示沒有future模塊，解決方案如下

1、安裝python3

sudo apt-get install python3

2、安裝

sudo apt-get install python3-tk

3、安裝pip3

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

sudo python3 get-pip.py

4、執行

sudo pip3 install future
5、執行

python3 -m mavgenerate
6、選擇xml文件、選擇輸出文件夾、選擇語言，點擊確定

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

另外個輸出文件夾隨便選

語言根據需要選擇

7、測試

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

編譯無錯誤

我是將輸出文件放在mavlink文件夾下的new-mavlink文件夾中
