Question

我正在使用罗斯布里奇。我当前的ros_distro是melodic。我无法使用error : Unable to load the manifest for package <pkg_name>订阅自定义消息。我sourced在另一个终端. ./devel/setup.bash中使用了bash文件，并使用了rospack find <pkg_name>，但这也产生了一个错误：找不到软件包。

这很奇怪，因为我可以在ROS中发布和订阅相同的主题。

我的目录结构如下：

overlay_ws
  build
  devel
  src
    CMakeLists.txt
    ros_tutorials
      CMakeLists.txt
      package.xml
      msg
        msg1
        msg2
        msg3
      scripts
        talker.py

这里是package.xml：

<?xml version="1.0"?>
<package format="2">

  <version>0.0.0</version>
