我已经从源代码在 CentOS 上安装了 Node.JS，如下所示：
yum install gcc-c++ make git
cd /usr/local/src/
git clone git://github.com/joyent/node.git
cd node
./configure
make
make install
但是在通过npm安装模块时出现错误：
sh: node-waf: command not found
npm ERR! threads_a_gogo@0.1.5 install: `node-waf configure install`
npm ERR! `sh "-c" "node-waf configure install"` failed with 127
npm ERR!
npm ERR! Failed at the threads_a_gogo@0.1.5 install script.
npm ERR! This is most likely a problem with the threads_a_gogo package,
npm ERR! not with npm itself.
npm ERR! Tell the author that this fails on your system:
npm ERR! node-waf configure install
npm ERR! You can get their info via:
npm ERR! npm owner ls threads_a_gogo
npm ERR! There is likely additional logging output above.
这个问题与 CentOS 相关，还是可能出了什么问题？此链接表明，仅当未从源安装 Node 时才会发生此错误....在这种情况下是.
