问题描述
catkin build 失败，原因是
Errors << mavlink:make /home/eia-lab1/catkin_ws/logs/mavlink/build.make.005.log

尽管安装了未来。
$ pip list | grep fut
future 0.18.2
我已经尝试了以下方法：
$ pip install -U future
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: future in /home/eia-lab1/.local/lib/python3.6/site-packages (0.18.2)
$ sudo -H pip install future

资源：
我开始认为这可能是路径采购问题！？我使用的是 Ubuntu 18.04 LTS。
解决方法
我无法添加评论，所以我走了。
-
您可能使用了错误版本的 python，请尝试使用更新或旧版本
-
模块可能在错误的文件中
这是我看到的唯一两件事，因为您已经尝试了各种安装方法
