I got error when using pip install leveldb

Question

When I used pip install leveldb in my MAC I got the error below, I searched the whole internet without any reply I could take with, my python env is 2.7, what made me upset

Answer 1

As you can see from the error message, the stdlibc++ implementation of the standard library cannot be found. One can 'resolve' this issue by instead using the stdc++ implementation. One way of doing this is by amending the flag CPPFLAG prior to your pip install:

export CPPFLAGS="-stdlib=libc++"

Answer 2

Some people have been able to fix this kind of issues by running

xcode-select --install

It is probably something related to your C++ installation. Here is a hint:

warning: include path for stdlibc++
