尝试了那两行命令，仍旧是同样的报错

小鱼

@LI 那就尝试用pip卸载重新安装写这个缺少的模块，不过这个模块代码应该就在你电脑上

@小鱼最后靠着重装ros2，没改文件内容，解决了问题

小鱼

@LI 解决环境问题最好的办法就是重装了

晤易

@小鱼鱼哥，我也遇到这个问题了。这个问题到底怎么解决呀，重装了ros也没用

小鱼

@晤易你是哪个版本的ros2

晤易

@小鱼 humble 版本的

沉淀

找了半天才找到这个解决办法，系统是22.04,安装ros humble，也是报相同的错误，亲测是Conda和本机环境冲突，需要用鱼哥说的在安装中先conda deactivate

晤易

@沉淀我是 conda deactivate了还是报错，然后把之前的编译文件和日志都删除了，再重新编译就不报错了

LIME

@晤易我的情况按照你说的解决了，这个坑困扰我了一下午了。
