npm更改前缀后没有响应 [英] npm not responding after changing the prefix

问题描述

我最近尝试通过npm更新我的IONIC CLI，安装成功了几次但CLI版本没有改变。经过研究后我决定更改npm前缀，然后IONIC strated抛出bash：未找到IONIC命令。然后我做了进一步的研究，之后我通过windows cmd admin编辑了npm配置。我做了

I tried updating my IONIC CLI through the npm recently, the installation were successful a couple of time but the CLI version did not change. After a research I decided to change the npm prefix, then the IONIC strated throwing up bash: IONIC command not found. Then I did a further research after which I edited the npm config through windows cmd admin. I did

 npm  cofig edit 

我将前缀更改为

 \users\<username>\

此后，npm不再响应。

since then, npm no longer respond.

如果我运行类似

npm install -g ionic

没有任何反应，没有错误或任何形式的回应。
我已卸载并重新安装该节点几次。我正在使用节点V4.2.2。

nothing happens, no errors nor any form of response. I have uninstall and reinstall the node several time. I am using node V4.2.2.

推荐答案

我终于找到了解决这个问题的方法。这些是我做的

I finally found a way around this . These are what I did

1. 我删除了所有应用程序中的所有node_module文件夹（我不确定这是否真的有必要）

1. I deleted all the node_module folders in all my application (I am not sure if this is really necessary )

我按照 https完全卸载了该节点：//stackoverflow.com/a/20711410/1363169

我跑了

npm root -g

返回路径

C:\Users\<username>\node_module

而不是

 /usr/local 

或安装节点的地方，在我自己的情况下节点安装在

or wherever node is installed , in my own case node is install in

 C:\Users\<username>\AppData\Roaming\npm

然后我跑

  npm config set prefix "C:\Users\<username>\AppData\Roaming\npm"

然后我又重新安装了cordova和离子

Then I reinstalled cordova and ionic again

    npm install  -g cordova
      npm install ionic -g

一切都很好
