-bash：express：command not found; -bash：ejs：command not found

标签： node.js bash express ejs

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

enter image description here

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。

参考：[在此输入链接描述] [1]

1.install ejs，发现错误：

[root@iZ94ywyr3sxZ node-v4.2.4-linux-x64]# sudo npm install -g ejs

npm http GET https://registry.npmjs.org/ejs

[root@iZ94ywyr3sxZ node-v4.2.4-linux-x64]# ejs -v
-bash: ejs: command not found

2.install继承并解决错误

[root@iZ94ywyr3sxZ node-v4.2.4-linux-x64]# npm install -g inherits
