cannot install this on Ubuntu: error: command 'g++' failed with exit status 1

When I install this pyworld with pip install pyworld or git clone this repo, I get error: command 'g++' failed with exit status 1.

g++ -pthread -shared -B /home/yons/anaconda3/compiler_compat -L/home/yons/anarld.o build/temp.linux-x86_64-3.6/lib/World/src/dio.o build/temp.linux-x86_64-3.6o build/temp.linux-x86_64-3.6/lib/World/src/synthesis.o build/temp.linux-x86_64-3World/src/synthesisrealtime.o build/temp.linux-x86_64-3.6/lib/World/src/codec.o b6_64-3.6/pyworld/pyworld.cpython-36m-x86_64-linux-gnu.so

I have no idea to do this. Thanks for your help.

@nicolaspanel @cnlinxi
Thank you for reporting this issue.
pip install pyworld continued on my machine even after the error. 😲

May you provide more info about your OS and packages?

Here's mine:

lsb_release -a
# No LSB modules are available.
# Distributor ID: Ubuntu
# Description:    Ubuntu 18.04.1 LTS
# Release:        18.04
# Codename:       bionic

gcc -v
# gcc version 7.4.0 (Ubuntu 7.4.0-1ubuntu1~18.04.1)

pip -V
# pip 19.2.3 from /home/jrm/miniconda3/envs/pyw/lib/python3.6/site-packages/pip (python 3.6)

BTW, my machine is a Surface Pro 4 running Windows Subsystem Linux (WSL).
