[SOLVED] Error: pngquant failed to build, make sure that libpng-dev is installed

I’m using centos 7.4

Error: pngquant failed to build, make sure that libpng-dev is installed

while executing

# npm install

✖ Error: pngquant failed to build, make sure that libpng-dev is installed

while trying to install libpng-devel , it say’s already installed

Solution

Update the nodejs & npm version if it’s using old one.

I have updated to

Nodejs Version

[[email protected] ~]# node -v
v8.10.0

Npm version

[[email protected] ~]# npm -v
5.7.1

Check the installed libpng-devel on your server.

[[email protected] ~]# rpm -qa |grep libpng
libpng-1.5.13-7.el7_2.x86_64
libpng-devel-1.5.13-7.el7_2.x86_64

If you are using epel repo,then it will install the latest version. For more libpng release check

[[email protected] ~]# yum list |grep libpng

I have installed following releases

yum install libpng12-1.2.50-10.el7.x86_64 libpng12-devel-1.2.50-10.el7.x86_64

move the node modules

mv node_modules node_modules_bak

Then type

# npm install

Done 100 % working … cheers 🙂
