I installed llvm too but still result is the same
(env) ishandutta2007@MacBook-Pro:~/Documents/Projects/my_proj$ brew reinstall llvm
==> Reinstalling llvm ==> Downloading https://homebrew.bintray.com/bottles/llvm-7.0.0.high_sierra.bottle.1.tar.gz
################################################################## 100.0%==> Pouring llvm-7.0.0.high_sierra.bottle.1.tar.gz
==> Caveats To use the bundled libc++ please add the following LDFLAGS: LDFLAGS="-L/usr/local/opt/llvm/lib -Wl,-rpath,/usr/local/opt/llvm/lib"
llvm is keg-only, which means it was not symlinked into /usr/local, because macOS already provides this software and installing another version in parallel can cause all kinds of trouble.
If you need to have llvm first in your PATH run: echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.bash_profile
For compilers to find llvm you may need to set: export LDFLAGS="-L/usr/local/opt/llvm/lib" export CPPFLAGS="-I/usr/local/opt/llvm/include"

回答1:
After reading the error log carefully, realised we need llvm version 6 instead of llvm version 7 which I had by default,
Step 1: brew install llvm@6
Step 2: Added the following to ~/.bashrc
export LLVM_CONFIG=/usr/local/opt/llvm@6/bin/llvm-config
Step 3: Reload ~/.bashrc
source ~/.bashrc
回答2:
If pip install is failing, you can try either of the following in Anaconda prompt:
easy_install librosa
OR
sudo pip install librosa
For me, easy_install worked fine!
