Once I type $sudo hexo d or with --debug, it shows

[error] 01:27:03.774 TypeError: Object message has no method 'replace'

I've checked the parser.js, everthing looks fine. I don't know why it will alert that has no method 'replace'?

here is my hexo version:
hexo: 2.8.3
os: Darwin 14.0.0 darwin x64
http_parser: 1.0
node: 0.10.32
v8: 3.14.5.9
ares: 1.9.0-DEV
uv: 0.10.28
zlib: 1.2.3
modules: 11
openssl: 1.0.1i
