Tried anything already, updated the version of gulp, node. Currently the latest versions. When node was on version 8.11.3, knocked out an error with the imagemin-pngquant plugin, it was the latest version 6.0.0, I changed it to 5.0.0, everything began to work, but I wanted to find out why it didn't work with the latest version, updated node, error With this plugin has disappeared, but everything works exactly nothing. I decided to lower the version of the plugin, again nothing works. He knocks this into the console, there are those who understand what the problem is or have encountered this? Before that, everything worked perfectly on the latest version of the plugin, I don’t understand why the gulp does not start ...
With version 6.0.0, this is knocked out:
