I had the error (Windows-MiKTeX): “Font xxxx... not found” (I don´t remember the font) and effectivelly, I´ve open the console and in Task menu I´ve apply the options "Refresh file name database" and "Refresh font map files" and it work out. 

1. 打开MiKTex Console

2.执行下列命令

-->Tasks-->Refresh file name database;

-->Tasks-->Refresh font map files;

-->Tasks-->Update package database;

-->Updates-->Check for updates-->Update Now;

 

3.更显之后，重新编译.tex文件，就没有pdflatex error: "Font ***... not found"错误提示信息了。
