把/usr/local/Cellar/node/4.2.1/libexec/npm/bin这个路径加到 $PATH 即可. 因为平时用npm装的包，可执行程序会在这下面创建软链接，所以这些命令可以直接用。但是不知道你的这个目录为什么没在 $PATH.

这样可以解决问题。不过你建议你再用nvm装下npm。之前那个npm可以不用管。如果装了curl的话，什么都不用改，直接curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.29.0/install.sh | bash。然后你的npm的bin应该是自动加在$PATH的。参考：github
