ROS：找不到包配置文件

Question

編輯：好的，所以我決定嘗試一些隨機的東西，我也將 rospy 指定為必需的組件。 我從我的 cmakelists 文件中刪除了所有 OpenCV 的東西，現在它只是吐出關於 rospy 的相同錯誤......以及與 std_msgs 相同的處理。 我首先在我正在使用 ROS 教程的這台計算機上使用 ROS，直到此時一切都運行良好。

我知道很多人都遇到了這個問題，運行 catkin_make/cmake 並看到它沒有找到您的 OpenCV 文件：

Could not find a package configuration file provided by "OpenCV" with any
  of the following names:

    OpenCVConfig.cmake
    opencv-config.cmake

當我嘗試僅使用 roscpp、rospy 等時，也會出現此錯誤：

  Could not find a package configuration file provided by "roscpp" with any
  of the following names:

roscppConfig.cmake
roscpp-config.cmake

這是我到目前為止所嘗試的：導出 OpenCV_DIR、CMAKE_PREFIX_PATH 等。人們在堆棧中建議的大部分內容。 還是出現這個錯誤。 檢查以確保我正確安裝了 OpenCV，使用 IDMTEST，我發現一切正常。 我可以在 python 等中完美地使用 opencv。

以及來自評論的 Tsyvarev 的解決方案：如果它是簡單的 find_package(OpenCV)，那么任何應該都有幫助： 1. cmake -DOpenCV_DIR=/usr/share/OpenCV .... 2. cmake -DCMAKE_PREFIX_PATH=/usr。 3. 導出 CMAKE_PREFIX_PATH=/usr。

我有這些 .cmake 文件位於：/usr/share/OpenCV 和 /usr/local/share/OpenCV

不確定它們是否可以位於其他任何地方，嘗試進行批量搜索，它似乎只是指向這兩個特定文件夾

瀏覽了我的 CMakeLists.txt 文件並按照 .cmake 文件的指示添加了目錄、目標庫等

我真的不知道此時該怎么辦。

一些代碼/文件：

    cmake_minimum_required(VERSION 2.8.3)

## Declare ROS messages, services and actions ##
################################################

## To declare and build messages, services or actions from within this
## package, follow these steps:
## * Let MSG_DEP_SET be the set of packages whose message types you use in
##   your messages/services/actions (e.g. std_msgs, actionlib_msgs, ...).
## * In the file package.xml:
##   * add a build_depend tag for "message_generation"
##   * add a build_depend and a run_depend tag for each package in MSG_DEP_SET
##   * If MSG_DEP_SET isn't empty the following dependency has been pulled in
##     but can be declared for certainty nonetheless:
##     * add a run_depend tag for "message_runtime"
## * In this file (CMakeLists.txt):
##   * add "message_generation" and every package in MSG_DEP_SET to
##     find_package(catkin REQUIRED COMPONENTS ...)
##   * add "message_runtime" and every package in MSG_DEP_SET to
##     catkin_package(CATKIN_DEPENDS ...)
##   * uncomment the add_*_files sections below as needed
##     and list every .msg/.srv/.action file to be processed
##   * uncomment the generate_messages entry below
##   * add every package in MSG_DEP_SET to generate_messages(DEPENDENCIES ...)

## Generate messages in the 'msg' folder
 add_message_files(
   FILES
   Num.msg

 )

## Generate services in the 'srv' folder
 add_service_files(
   FILES
   AddTwoInts.srv
 )

## Generate actions in the 'action' folder
# add_action_files(
#   FILES
#   Action1.action
#   Action2.action
# )

## Generate added messages and services with any dependencies listed here
 generate_messages(
   DEPENDENCIES
   std_msgs  # Or other packages containing msgs
 )

################################################
## Declare ROS dynamic reconfigure parameters ##
################################################

## To declare and build dynamic reconfigure parameters within this
## package, follow these steps:
## * In the file package.xml:
##   * add a build_depend and a run_depend tag for "dynamic_reconfigure"
## * In this file (CMakeLists.txt):
##   * add "dynamic_reconfigure" to
##     find_package(catkin REQUIRED COMPONENTS ...)
##   * uncomment the "generate_dynamic_reconfigure_options" section below
##     and list every .cfg file to be processed

## Generate dynamic reconfigure parameters in the 'cfg' folder
# generate_dynamic_reconfigure_options(
#   cfg/DynReconf1.cfg

Answer 1

 Could not find a package configuration file provided by "roscpp" with
 any of the following names:

         roscppConfig.cmake
         roscpp-config.cmake

如果 ROS 是依賴項並且未安裝，則會發生這種情況。 從這里安裝它： http : //wiki.ros.org/ROS/Installation並重復。

Answer 2

如果有人像我一樣尋找簡單的解決方案來到這里，這就是訣竅：

sudo apt-get install ros-<distro>-roscpp

替換為您的 ROS 發行版，例如：

sudo apt-get install ros-melodic-roscpp
