sudo升级后，catkin无法找到qt_build

编程问答 2022-06-22

问题描述

我正在从事我的项目，而我不小心做了sudo apt-get升级。 现在我有一些我不明白的问题。

当我在工作区中执行catkin_make时，它说找不到qt_build软件包，需要将其安装在CMAKE_PREFIX_PATH中。

    CMake Warning at /opt/ros/kinetic/share/catkin/cmake/catkinConfig.cmake:76 (find_package):
  Could not find a package configuration file provided by "qt_build" with any
  of the following names:

    qt_buildConfig.cmake
    qt_build-config.cmake

  Add the installation prefix of "qt_build" to CMAKE_PREFIX_PATH or set
  "qt_build_DIR" to a directory containing one of the above files.  If
  "qt_build" provides a separate development package or SDK,be sure it has
  been installed.
Call Stack (most recent call first):
  motion_manager/CMakeLists.txt:31 (find_package)

---Could not find the required component 'qt_build'. The following CMake error indicates that you either need to install the package with the same name or change your environment so that it can be found.

但是，软件包qt_build已经在该目录中。

在升级之前，一切正常，但是现在出现此错误。

有人知道如何解决此类问题吗？谢谢
