我正在尝试按照以下说明在 Mac 上安装 Apache Pulsar C++ 客户端： https://github.com/apache/pulsar/tree/master/pulsar-client-cpp#compile-on-mac-os-x

不幸的是，当我运行cmake . 步骤时，我得到了以下响应：

我用brew安装了boost、boost-python和cmake，但是cmake好像没有看到python boost。

【解决方案1】：

我可以通过编辑pulsar/pulsar-client-cpp 下的主要CMakeLists.txt 文件找到解决方法：

if (PYTHONLIBS_VERSION_STRING MATCHES "^3.+$")
        MESSAGE(STATUS "DETECTED Python 3")
        string(REPLACE "." ";" PYTHONLIBS_VERSION_NO_LIST ${PYTHONLIBS_VERSION_STRING})
        list(GET PYTHONLIBS_VERSION_NO_LIST 0 PYTHONLIBS_VERSION_MAJOR)
        list(GET PYTHONLIBS_VERSION_NO_LIST 1 PYTHONLIBS_VERSION_MINOR)
        set(BOOST_PYTHON_NAME_POSTFIX ${PYTHONLIBS_VERSION_MAJOR}${PYTHONLIBS_VERSION_MINOR})
        # For python3 the lib name is boost_python3
        set(BOOST_PYTHON_NAME_LIST python3;python3-mt;python-py${BOOST_PYTHON_NAME_POSTFIX};python${BOOST_PYTHON_NAME_POSTFIX}-mt;python${BOOST_PYTHON_NAME_POSTFIX})
    else ()
        # Regular boost_python
        set(BOOST_PYTHON_NAME_LIST python3;python37;python;python-mt;python-py27;python27-mt;python27)
    endif ()

此解决方案确实需要使用brew install boost-python3。

我怀疑如果python 与python27 切换它也会起作用。我的python 安装的是2.7。
