如果是使用树莓派的家人们可以考虑执行以下命令，速度虽然慢了点，但是可以很有效的防止内存100%：
export MAKEFLAGS="-j 1"
colcon build --executor sequential

@624753336 请问你解决了吗

@xiaolixi123 在 ROS2的参数Parameters通信接口和函数参数为啥不一致，一个数组一个是对象 中说：

rcl_interfaces/srv/SetParameters的返回参数为啥和parameters_callback的返回参数不一致
rcl_interfaces/srv/SetParameters的返回参数

答案在这里，代码种仅仅是对一个参数调用的，也就是接口是数组，但是代码确实一个个调用的。

注意reason只有是False的时候才能传给调用端，True的时候reason调用端是空的。

@3213447731 你好，我不清楚你是否解决了这个问题，但是我试用了一种方案可以成功安装，你可以把ROS2的源换成官方的源，也就是第二次选择时选择官方ROS源进行foxy的安装，之后虽然会出现python的依赖等问题，但是可以安装成功，安装成功后你再使用sudo apt install 或者pip等指令安装缺少的python依赖，这样就可以安装成功相关ROS和依赖了。

看你的ros版本，然后把指令最后面的版本改为你的ros版本就好了。

@1691904680 解决了吗

你好，小鱼。这个时区是UTC-0时区吧？不需要转换到UTC+8时区吗？

@1872311876 佬，解决了吗，我这边也是用robot_localization融合imu和odom后odometry的值比原始odom要差8e1fc7b1-ed2b-4141-b0e5-22d863577351-image.png

@杜守钰 你好，我这边是用static tf 去发布传感器到base_link之间的tf关系的，我也遇到了大量的message filter刷屏打印，有什么解决方式吗？

返回工作空间根目录执行就好了

@Sachham 已解决，main拼写错了
