ros 错误集合
总结学习ros中遇到的一些错误
"cmake" failed
（1）cmake:11(message):
CMake Error at /opt/ros/kinetic/share/catkin/cmake/safe_execute_process.cmake:11 (message):

returned error code 1
删除掉工作空间src里面的一个package后再catkin_make就出现这个错误
解决： pip install catkin_pkg.
You probably need to install other required Python packages like nose. Then remove the build folder, as the Python PATH seems to be cached there rm -rf ./build 再重新catkin_make c
(2) cmake:83(find package)
安装缺的包可以解决
rosdep install --from-paths src --ignore-src --rosdistro kinetic -y
serialConfig ：sudo apt-get install ros-kinetic-serial
gazebo加载缓慢或不能加载

火狐浏览器安装百度云插件
https://addons.mozilla.org/zh-CN/firefox/addon/baidu-pan-exporter/
添加完插件后重启火狐浏览器，再百度网盘下载界面会出现导出下载，点击文本导出，复制文本框内的下载链接，打开一个终端，粘贴回车后（可能要安装aria2）开始下载。下载目录就在链接的开头部分。
sudo chmod 777 目录 可以修改只读文件夹的权限，之后就可以复制文件进去
rospack list | grep ros_ws 找不到包
得重新source ~/ros_ws/devel/setup.bash 后才能找到，尽管已经添加进.bashrc文件，这也可能是之前roscore,提示roscore未安装的原因, 得重新source /opt/ros/kinetic/setup.bash

ubuntu下 ~/.bash_profile 环境变量配置是 vim ~/.profile
执行.py 找不到文件

无法获得锁 /var/lib/apt/lists/lock - open
sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock
因为提示可以automove一些没用到的包，导致一些ros包被删了
cmake时报错
(1)
Could not find a package configuration file provided by “diagnostic_updater” with any of the following names:
diagnostic_updaterConfig.cmake
diagnostic_updater-config.cmake
sudo apt-get install ros-kinetic-diagnostics
(2)Could not find a package configuration file provided by "industrial_msgs"
sudo apt-get install ros-kinetic-industrial-core
(3)Could not find a package configuration file provided by "interactive_markers"
apt-get install ros-kinetic-interactive-markers
（4），居然rviz和moveit都被删了
sudo apt-get install rviz
sudo apt-get install ros-kinetic-moveit
ROS由于公钥更新导致用户apt-get update报错解决办法(下载软件仓库信息失败 检查您的网络连接)
