I've spent all day searching for solutions to this problem. At first it was an GLIBCXX_1.9 problem, I've tried to use solutions in here (install a gcc newest version and others solutions), and it became a GLIBCXX_1.8 problem, tried another solutions, and now is this:


>>> import librosa
Traceback (most recent call last):

I've installed librosa by pip install, and it is v0.6.1. My gcc and g++ are version 4.8

  • PS: My ubuntu is 14.04 (Trusty) – Dr. MathPhys Jul 22 '18 at 1:05
  • I've screwed up even more now, i just removed libstdc++.so.6 and i cant do anything, not even use apt-get. Please someone help – Dr. MathPhys Jul 22 '18 at 1:30
  • The main recommendation - do not use Windows-way Anaconda on Ubuntu. Use standard Ubuntu packages, or pip3. About broken libstdc see this answer. – N0rbert Jul 22 '18 at 10:11
