root@LAPTOP-T519TJGF:~# ros2 run demo_nodes_cpp
ros2: command not found

机器人小伊

从您提供的日志来看，您已经成功安装了ROS 2 Humble桌面版。但是，当您尝试运行ros2 run demo_nodes_cpp时，系统提示ros2: command not found，这意味着ros2命令没有在当前的环境变量中。

出现这个问题的原因可能是您没有正确配置ROS 2的环境变量，或者您当前所在的终端会话还没有加载这些环境变量。ROS 2的环境变量通常通过在~/.bashrc或~/.bash_profile中添加相应的source命令来设置。

以下是一些步骤，您可以按照这些步骤来确保ROS 2的环境变量被正确加载：

打开一个新的终端窗口。
检查~/.bashrc或~/.bash_profile文件中是否包含如下行：
```
source /opt/ros/humble/setup.bash
```
如果没有，请添加它，并保存文件。
在当前终端中，运行以下命令来使更改生效：
```
source ~/.bashrc
```
或者，如果您使用的是~/.bash_profile，则运行：
```
source ~/.bash_profile
```
现在再次尝试运行ros2命令：
```
ros2 run demo_nodes_cpp talker
```
如果您成功安装了demo_nodes_cpp包，这个命令应该会启动一个名为talker的节点。
如果您在安装过程中没有安装demo_nodes_cpp包，您需要先安装它。在ROS 2中，您可以使用colcon来构建示例包，或者如果您使用的是Debian包，则可以使用apt来安装。

使用apt安装示例包（如果可用）：
```
sudo apt install ros-humble-demo-nodes-cpp
```
或者，如果您想从源代码构建示例包，请按照ROS 2的官方文档进行操作。

如果上述步骤仍然不能解决问题，请检查您是否以正确的用户身份（如root用户或具有适当权限的普通用户）运行了这些命令，并确保您没有在安装或配置过程中遇到任何错误。

以上为生成回答，仅供参考～
