LaTeX CJK 字体错误信息！

如果在Linux下用gvim编译tex文件，并使用了CJK库，同时自定义了字号后会出现如下错误信息：
......
|| LaTeX Font Warning: Font shape `OT1/cmss/bx/n' in size <4> not available
|| LaTeX Font Warning: Font shape `OT1/cmss/m/n' in size <4> not available
|| LaTeX Font Warning: Size substitutions with differences

从而导致gvim无法继续编译。

那么如何解决呢？其实只要注意加入times包就行了，比如：
\usepackage{CJK}
\usepackage{times}
