python - 在 Alpine Edge 中安装 py[2]-numpy（Alpine 3.10 是最新的并且具有 py[2]-numpy）

Question

由于gdaland proj(aka proj4) 仅在 Alpine Edge （“测试”存储库）中可用，我被锁定到该分支。

使用 Python 3 时， Python 模块gdal（不是上面提到的库）不能在 Alpine Edge 上编译，所以这使我无法使用 Python 2。

我收到很多错误，例如

    extensions/gdal_wrap.cpp: In function 'CPLErr GDALDatasetShadow_SetGCPs2(GDALDatasetShadow*, int, const GDAL_GCP*, OSRSpatialReferenceShadow*)':
    extensions/gdal_wrap.cpp:4735:12: error: 'GDALSetGCPs2' was not declared in this scope; did you mean 'GDALSetGCPs'?
     4735 |     return GDALSetGCPs2( self, nGCPs, pGCPs, (OGRSpatialReferenceH)hSRS );
          |            ^~~~~~~~~~~~
          |            GDALSetGCPs

     7850 |       int res = PyObject_AsReadBuffer(obj0, &safeBuf, &safeLen);
          |                                                               ^
    In file included from /usr/include/python3.7m/Python.h:147,
                     from extensions/gdal_wrap.cpp:173:
    /usr/include/python3.7m/abstract.h:489:17: note: declared here
      489 | PyAPI_FUNC(int) PyObject_AsReadBuffer(PyObject *obj,
          |                 ^~~~~~~~~~~~~~~~~~~~~

我认为这是由于这个 Python 版本不匹配造成的。

我需要使用py-numpy( py2-numpy) +-dev包以及py2-matplotlib，但这些在 Edge 分支存储库中不可用。那个只有那些为 Python 3 预编译的包。

Python 2 的 3.10 分支中存在 numpy 和 matplotlib 包。

有没有办法可以在 Edge 分支中使用/安装它们？

这是我的 Dockerfile 的相关部分
