cc1plus: fatal error: knn.cxx: No such file or directory

[nicetomeet-you]

recently,im running compile_op.sh like this:
`
cd utils/nearest_neighbors
python setup.py install --home="."
cd ../../

cd utils/cpp_wrappers
sh compile_wrappers.sh
cd ../../../
`

AND i get this:
running install running build running build_ext building 'nearest_neighbors' extension /usr/bin/gcc -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I./ -I/root/miniconda3/lib/python3.8/site-packages/numpy/core/include -I/root/miniconda3/include/python3.8 -c knn.cxx -o build/temp.linux-x86_64-3.8/knn.o -std=c++11 -fopenmp cc1plus: warning: command-line option ‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++ cc1plus: fatal error: knn.cxx: No such file or directory compilation terminated. error: command '/usr/bin/gcc' failed with exit status 1
It told me knn.cxx is miss ,so where is it? or how can i solve this issue?

utils/nearest_neighbors/knn.pyx:

distutils: sources = knn.cxx

replace knn.cxx by knn_.cxx
