Plugin Loading Issue

After installing Vuepress 1.x and the plugin, trying to run the command leads to the following:

At C:\Users\domin\AppData\Local\Yarn\bin\vuepress.ps1:5 char:13
+     *CYGWIN*) basedir=`cygpath -w "$basedir"`;;
+             ~

Can anyone help me out with troubleshooting this?
