Trouble executing ./configure with mapnik 3.0.19. Error reported

[tthh7]

I use the following command

"PYTHON=python3 ./configure PREFIX=/usr/local/third_party BOOST_INCLUDES=/usr/local/third_party/include BOOST_LIBS=/usr/local/third_party/lib CAIRO_INCLUDES=/usr/local/third_party/include CAIRO_LIBS=/usr/local/third_party/lib PNG_INCLUDES=/usr/local/third_party/include PNG_LIBS=/usr/local/third_party/lib PROJ_INCLUDES=/usr/local/third_party/include PROJ_LIBS=/usr/local/third_party/lib TIFF_INCLUDES=/usr/local/third_party/include TIFF_LIBS=/usr/local/third_party/lib WEBP_INCLUDES=/usr/local/third_party/include WEBP_LIBS=/usr/local/third_party/lib HARFBUZZ_INCLUDES=/usr/local/third_party/include HARFBUZZ_LIBS=/usr/local/third_party/lib JPEG_INCLUDES=/usr/local/third_party/include JPEG_LIBS=/usr/local/third_party/lib FREETYPE_INCLUDES=/usr/local/third_party/include/freetype2 FREETYPE_LIBS=/usr/local/third_party/lib RUNTIME_LINK=static CXX=g++ CC=gcc CUSTOM_CXXFLAGS='-g -D_GLIBCXX_USE_CXX11_ABI=0' PKG_CONFIG_PATH=/usr/local/third_party/lib/pkgconfig"

to configure， but in the end, I encounter the following error:

"All Required dependencies found!
Overwriting and re-saving file 'config.py'...
Will hold custom path variables from commandline and python config file(s)...
AttributeError: Can't pickle local object 'Classic.init.._scan':
File "/root/mapnik/SConstruct", line 1977”
pickle.dump(pickle_dict, env_cache)"

How can I resolve this error?
