#### 介绍

#### 安装教程

1. 下载rpm包

aarch64:

```
wget https://117.78.1.88/build/home:Chenjy3_22.03/openEuler_22.03_LTS_standard_aarch64/aarch64/message_filters/ros2-foxy-ros2-message_filters-3.2.5-2.oe2203.aarch64.rpm
```

x86_64:

```
wget https://117.78.1.88/build/home:Chenjy3_22.03/openEuler_22.03_LTS_standard_x86_64/x86_64/message_filters/ros2-foxy-ros2-message_filters-3.2.5-2.oe2203.x86_64.rpm
```

2. 安装rpm包

aarch64:

```
sudo rpm -ivh --nodeps --force ros2-foxy-ros2-message_filters-3.2.5-2.oe2203.aarch64.rpm
```

x86_64:

```
sudo rpm -ivh --nodeps --force ros2-foxy-ros2-message_filters-3.2.5-2.oe2203.x86_64.rpm
```
