Multiple packages found with the same name "msgs_demo":

这个错误通常出现在 Android 项目中,意味着存在多个版本的同名依赖包。解决这个错误的方法是使用 `exclude` 关键字来移除冲突的依赖包。
例如,假设你的项目中有两个依赖包 A 和 B,它们都依赖了同一个包 `msgs_demo`,但是它们的版本不同。你可以在 B 的依赖声明中使用 `exclude` 关键字来移除 `msgs_demo`:
```
implementation('dependency-B') {
exclude group: 'com.example', module: 'msgs_demo'
}
```
这样,编译器就会使用 A 中的版本来解决冲突。如果你需要使用 B 中的特定版本,你可以尝试更新 A 的版本,或者查找其他版本兼容的依赖包。

ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: slam_sim_demo: Cannot locate rosdep definition for [hector_mapping] navigation_sim_demo: Cannot locate rosdep definition for [dwa_local_planner] robot_sim_demo: Cannot locate rosdep definition for [yocs_cmd_vel_mux] Continuing to install resolvable dependencies...
这个错误是由于ROS依赖管理工具rosdep无法找到某些软件包的依赖项所导致的。在这种情况下,您可以尝试手动安装这些软件包的依赖项,或者更新rosdep缓存以解决依赖项问题。
要更新rosdep缓存,请运行以下命令:
```
sudo rosdep init
rosdep update
```
要手动安装软件包的依赖项,请使用以下命令:
```
sudo apt-get install <dependency-name>
```
在这个例子中,您需要安装以下软件包的依赖项:
- hector_mapping
- dwa_local_planner
- yocs_cmd_vel_mux
您可以使用以下命令来查找软件包的依赖项:
```
rosdep check <package-name>
```
这将列出软件包的所有依赖项及其状态。
/bin/sh: mysql_config: command not found /bin/sh: mariadb_config: command not found /bin/sh: mysql_config: command not found
These errors indicate that the system is unable to locate the "mysql_config" or "mariadb_config" command. This could be due to a missing package or an incorrect installation.
To resolve this issue, you can try the following steps:
1. Install the MySQL or MariaDB development package by running the following command:
For MySQL:
```
sudo apt-get install libmysqlclient-dev
```
For MariaDB:
```
sudo apt-get install libmariadbclient-dev
```
2. If the above command does not work, you can try locating the "mysql_config" or "mariadb_config" command manually by running the following command:
```
sudo find / -name mysql_config
```
If the command is found, update the PATH environment variable to include the directory where the command is located. For example, if the command is located in "/usr/local/mysql/bin", you can add the following line to your .bashrc or .bash_profile file:
```
export PATH=$PATH:/usr/local/mysql/bin
```
3. If the above steps do not work, you may need to reinstall MySQL or MariaDB and ensure that the required development packages are installed.
