****
i check this "gulp-javascript-obfuscator" folder and src not exist.
then reinstall 'gulp-javascript-obfuscator' ,
but again i get that error.
i think problem is "utf-8" when reading file.

Reproduzca la tarea de gulp indicada usando gulp.src('./src/inject/temp2-min.js') y javascriptObfuscator(), y comience después por src/index.ts alrededor de la llamada a validateSync y las entradas de la pila de javascript-obfuscator Options.ts. Confirme si el fallo se debe a que falta la ruta src del paquete, al procesamiento de la entrada o a la codificación, y verifique que la tarea se complete sin el error indicado.
