用npm命令，在win7 64位系统下安装mongodb，总出现这样的报错：

。。。。。 206 error bson@0.1.8 install: (node-gyp rebuild 2> builderror.log) || (exit 0) 206 error spawn ENOENT 207 error Failed at the bson@0.1.8 install script. 207 error This is most likely a problem with the bson package, 207 error not with npm itself. 207 error Tell the author that this fails on your system: 207 error (node-gyp rebuild 2> builderror.log) || (exit 0) 207 error You can get their info via: 207 error npm owner ls bson 。。。。。

但是直接下载安装mongo压缩包，单独启动，可以启动成功。

郁闷中。。。 有人知道是怎么回事吗
