在搜索主要錯(cuò)誤消息的解決方案之后c++: error: unrecognized command line option '-R'
我所做的是使用強(qiáng)大的方法搜索相關(guān)文件find：

version 3.8接下來，我打開了包含當(dāng)前在我的文本編輯器中使用的相關(guān) python 文件VS Code。然后，我在這些文件中搜索“-R”以找到以下代碼片段：
? ? ? ? else:
? ? ? ? ? ? if self._is_gcc(compiler):
? ? ? ? ? ? ? ? # gcc on non-GNU systems does not need -Wl, but can
? ? ? ? ? ? ? ? # use it anyway.? Since distutils has always passed in
? ? ? ? ? ? ? ? # -Wl whenever gcc was used in the past it is probably
? ? ? ? ? ? ? ? # safest to keep doing so.
? ? ? ? ? ? ? ? if sysconfig.get_config_var("GNULD") == "yes":
? ? ? ? ? ? ? ? ? ? # GNU ld needs an extra option to get a RUNPATH
? ? ? ? ? ? ? ? ? ? # instead of just an RPATH.
? ? ? ? ? ? ? ? ? ? return "-Wl,--enable-new-dtags,-R" + dir
? ? ? ? ? ? ? ? else:
? ? ? ? ? ? ? ? ? ? return "-Wl,-R" + dir
? ? ? ? ? ? else:
? ? ? ? ? ? ? ? # No idea how --enable-new-dtags would be passed on to
? ? ? ? ? ? ? ? # ld if this system was using GNU ld.? Don't know if a
? ? ? ? ? ? ? ? # system like this even exists.
? ? ? ? ? ? ? ? return "-R" + dir
在這個(gè)代碼片段中，我用"-R"和"-rpath="最后一個(gè)獨(dú)立的"-R"（上面代碼片段的最后一行）甚至用'-Wl,-rpath='. 完成后，代碼片段如下所示：
? ? else:
? ? ? ? if self._is_gcc(compiler):
? ? ? ? ? ? # gcc on non-GNU systems does not need -Wl, but can
? ? ? ? ? ? # use it anyway.? Since distutils has always passed in
? ? ? ? ? ? # -Wl whenever gcc was used in the past it is probably
? ? ? ? ? ? # safest to keep doing so.
? ? ? ? ? ? if sysconfig.get_config_var("GNULD") == "yes":
? ? ? ? ? ? ? ? # GNU ld needs an extra option to get a RUNPATH
? ? ? ? ? ? ? ? # instead of just an RPATH.
? ? ? ? ? ? ? ? return "-Wl,--enable-new-dtags,-rpath=" + dir
? ? ? ? ? ? else:
? ? ? ? ? ? ? ? return "-Wl,-rpath=" + dir
? ? ? ? else:
? ? ? ? ? ? # No idea how --enable-new-dtags would be passed on to
? ? ? ? ? ? # ld if this system was using GNU ld.? Don't know if a
? ? ? ? ? ? # system like this even exists.
? ? ? ? ? ? return "-Wl,-rpath=" + dir
保存并關(guān)閉上述修改后的python-scripts后，cartopy的安裝終于成功了：
