怎么解决这个?

您可以通过在cmake
命令后附加填充相应文件夹的-DPYTHON_LIBRARY
和-DPYTHON_INCLUDE_DIR
标记来修复错误。
因此,诀窍是使用python解释器返回的信息填充这些参数,这是最可靠的。这可能独立于您的python位置/版本(也适用于Anaconda用户):
$ cmake .. \
-DPYTHON_INCLUDE_DIR=$(python -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())") \
-DPYTHON_LIBRARY=$(python -c "import distutils.sysconfig as sysconfig; print(sysconfig.get_config_var('LIBDIR'))")
如果你要链接到cmake的python版本是Python3.X而默认的python符号链接指向Python2.X,则可以使用python3 -c ...
代替python -c ...
。
如果错误仍然存在,您可能需要按照@pdpcosta的说明将cmake
更新为更高版本,然后重复此过程。

我遇到了同样的问题,并发现错误消息提供了误导性的变量名称。尝试设置以下内容(单数而不是复数):
PYTHON_INCLUDE_DIR=/usr/include/python2.7
PYTHON_LIBRARY=/usr/lib/python2.7/config/libpython2.7.so
您看到的错误消息的(复数)变量是PythonLibs在正确初始化时设置的值。

I was facing this problem while trying to compile OpenCV 3 on a Xubuntu 14.04 Thrusty Tahr system. With all the dev packages of Python installed, the configuration process was always returning the message:
Could NOT found PythonInterp: /usr/bin/python2.7 (found suitable version "2.7.6", minimum required is "2.7")
Could NOT find PythonLibs (missing: PYTHON_INCLUDE_DIRS) (found suitable exact version "2.7.6")
Found PythonInterp: /usr/bin/python3.4 (found suitable version "3.4", minimum required is "3.4")
Could NOT find PythonLibs (missing: PYTHON_LIBRARIES) (Required is exact version "3.4.0")
The CMake version available on Thrusty Tahr repositories is 2.8. Some posts inspired me to upgrade CMake. I've added a PPA CMake repository which installs CMake version 3.2.
After the upgrade everything ran smoothly and the compilation was successful.

对我来说下一步是有帮助的:
> apt-get install python-dev python3-dev
答案 4 :(得分:7)
Ubuntu的某些最新版本默认安装Python 3.4,而Ubuntu(2.8)的CMake版本只搜索Python 3.3。
尝试在set(Python_ADDITIONAL_VERSIONS 3.4)
声明之前添加find_package
。
请记得清除CMakeCache.txt
。

此问题也可能发生在Windows中。 Cmake查看注册表,有时候没有设置python值。对于那些有类似问题的人:

只需创建.reg文件即可设置必要的密钥并进行相应编辑以符合您的设置。

即使按照上面的建议添加-DPYTHON_INCLUDE_DIR
和-DPYTHON_LIBRARY
,我仍然面临错误Could NOT find PythonInterp
。解决这个问题的方法是按照https://github.com/pybind/pybind11/issues/99#issuecomment-182071479:
-DPYTHON_EXECUTABLE:FILEPATH=
添加到cmake
cmake .. \
-DPYTHON_INCLUDE_DIR=$(python -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())") \
-DPYTHON_LIBRARY=$(python -c "import distutils.sysconfig as sysconfig; print(sysconfig.get_config_var('LIBDIR'))") \
-DPYTHON_EXECUTABLE:FILEPATH=`which python`

将此粘贴到您的CMakeLists.txt中:
# find python
execute_process(COMMAND python-config --prefix OUTPUT_VARIABLE PYTHON_SEARCH_PATH)
string(REGEX REPLACE "\n$" "" PYTHON_SEARCH_PATH "${PYTHON_SEARCH_PATH}")
file(GLOB_RECURSE PYTHON_DY_LIBS ${PYTHON_SEARCH_PATH}/lib/libpython*.dylib ${PYTHON_SEARCH_PATH}/lib/libpython*.so)
if (PYTHON_DY_LIBS)
list(GET PYTHON_DY_LIBS 0 PYTHON_LIBRARY)
message("-- Find shared libpython: ${PYTHON_LIBRARY}")
else()
message(WARNING "Cannot find shared libpython, try find_package")
endif()
find_package(PythonInterp)
find_package(PythonLibs ${PYTHON_VERSION_STRING} EXACT)
答案 8 :(得分:0)
请注意,如果您使用的cMake版本是3.12或更高版本,则变量PythonInterp
和PythonLibs
已更改为Python
。
因此我们使用:
find_package(Python ${PY_VERSION} REQUIRED)
代替:
find_package(PythonInterp ${PY_VERSION} REQUIRED)
find_package(PythonLibs ${PY_VERSION} REQUIRED)
有关详细信息,请参见https://cmake.org/cmake/help/v3.12/module/FindPython.html。

以防万一,我通过查看cmake doc找到了类似问题的解决方法: https://cmake.org/cmake/help/v3.0/module/FindPythonLibs.html
您必须为cmake设置两个env var才能找到一致的版本。 不幸的是,这不是通用解决方案...
cmake -DPYTHON_LIBRARY=${HOME}/.pyenv/versions/3.8.0/lib/libpython3.8.a -DPYTHON_INCLUDE_DIR=${HOME}/.pyenv/versions/3.8.0/include/python3.8/ cern_root/

如果以上所有方法都不起作用,也许下面的命令行对您有用。
