Centos npm install sharp failed, when libvips installed manually

[helloqhx]

I have manually installed vips on my centos 6.5 box. As follows:
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
pkg-config --modversion vips-cpp
8.4.1

But, when npm install sharp, it output:

node-gyp rebuild

ERROR: glibc version 2.12 requires manual installation
gyp: Call to 'LDD_VERSION="ldd (GNU libc) 2.12

I omitted some path info.

Can anyone help?
Thanks very much.
Oh, please do not force me to upgrade my OS, it's not in my charge.

sharp v0.17.x requires libvips v8.4.2+
