Llamafile embeddings 503 error

[tho1np]

When I try to follow instructions in https://docs.llamaindex.ai/en/stable/examples/embeddings/llamafile/
it threw me 503 error.
Then I tried Llamafiler instructions in https://github.com/Mozilla-Ocho/llamafile/blob/main/llamafile/server/doc/getting_started.md but make -jthrew the following error

process_begin: CreateProcess(NULL, uname -m, ...) failed.
build/config.mk:23: pipe: Bad file descriptor
The syntax of the command is incorrect.
build/download-cosmocc.sh 
process_begin: CreateProcess(NULL, sh C:\Users\tho1np\llamafile\build\download-cosmocc.sh, ...) failed.
make (e=2): The system cannot find the file specified.
make: *** [build/config.mk:56: .cosmocc/3.9.6] Error 2

What am I missing?
