How does this toolchain work？

[ChrisYeGX]

When I try to install library(lxml,paramiko) that have dependencies with C library by using pip, it raise the error that :
/home/QPY/android-ndk-r17/toolchain/llvm/prebuilt/linux-x86_64/bin/clang : no such file
How can I solve this problem? Should I put the tool chain in that directory?
Waiting for your reply.
