引：在安裝完nodejs後，通過npm下載全域模組預設安裝到{%USERDATA%}C:\Users\username\AppData\下的Roaming\npm下，這當然是不太對的預設。

 

1，安裝LTS版本的nodejs，本文為v6.10.2 (includes npm 3.10.10) .msi，nodejs安裝路徑會自動添加到PATH環境變數；

本文安裝路徑為：D:\Program Files\nodejs

修改完成之後：

2，在nodejs安裝路徑下建立檔案夾node_cache用來存放下載包的緩衝； 即：D:\Program Files\nodejs\node_cache；

 

3，運行 npm config set cache "D:\Program Files\nodejs\node_cache" 設定快取檔案夾；

運行npm config set prefix "D:\Program Files\nodejs"設定全域模組存放路徑；

注意：nodejs會自動尋找該路徑下的node_modules檔案夾為實際存放全域模組的路徑，這也是為啥叫prefix不叫global的原因；

以後安裝的全域模組都會被放到D:\Program Files\nodejs\node_modules下，跟npm模組在一個檔案夾中；

 

4，修改D:\Program Files\nodejs\node_modules\npm\npmrc檔案，將預設值改為：

prefix=D:\Program Files\nodejs，如果不做這個修改，則npm在運行 npm ls  -g 的時候，仍然以預設的路徑來尋找已安裝的全域模組；

 

5，運行npm install express -g 以全域方式安裝express模組，可發現，在D:\Program Files\nodejs\node_modules下出現express檔案夾；

6，運行npm list -g ，列出所有全域模組：

D:\Program Files\nodejs

包含了express和npm兩個模組，及其相依模組；

 

7，最後有潔癖的同學可以將使用者環境變數中的預設路徑刪除；

本文包含的方法，並不需要另外設定PATH變數；
