在Linux虚拟服务器（CenterOS 6.5）中安装节点后，我想安装express和ejs，我遇到了一个奇怪的问题：-bash：express: command not found， - bash：ejs: command not found
但是在“/ usr / local / lib / node_modules”中，已经安装了ejs。
我不知道为什么。节点是否未正确安装或其他？
希望有人可以帮助我，我已经挣扎了几天。

根据控制台"npm WARN unmet dependency /usr/lib/node_modules/block-stream requires inherits@'~2.0.0' but will load"，“继承”是解决此问题的关键。
