Nodejs installation, environment configuration, and removal of NPM global configuration under Windows system

Nodejs Installing and setting NPM global paths

Remove NPM Global Path configuration

First, Nodejs install and set NPM global pathFirst step: Download the installation file

Download Nodejs, official website: http://nodejs.org/download/, I download here is node-v8.4.0-x64.msi, such as

Step Two: Install Nodejs

After the download is complete, double-click "Node-v0.10.28-x86.msi" to start installing Nodejs and customize the installation under D:\Program Files\nodejs.

In the cmd console input: node-v, the console will print out: v0.10.28, the version prompt indicates that the installation was successful.

Check the system environment variable path , if there is an automatic add Nodejs installation directory, such as, finally have automatically added my installation directory;

C:\programdata\oracle\java\javapath;%systemroot%\system32;%systemroot%;%systemroot%\system32\wbem;%systemroot %\system32\windowspowershell\v1.0\; C:\Program Files\tortoisesvn\bin;d:\program Files\tortoisesvn0\bin; C:\Program Files\emeditor;%java_home%\bin;%java_home%\jre\bin; C:\Program Files\Microsoft SQL Server\ the\tools\binn\; C:\Program files\dotnet\;%android_home%\tools;%android_home%\platform-tools;%java_home%\bin;%android_home%\ Tools;%android_home%\platform-tools;%android_home%\build-tools\21.1.2;D: \program Files\apache-ant-1.9.9-bin\apache-ant-1.9.9\bin;%gradle_home%\bin;%systemroot%\system32;%systemroot%;%systemroot%\system32\wbem; C:\users\administrator.cn-20151209rina\appdata\roaming;d:\program files\nodejs\; C:\programdata\oracle\java\javapath;%systemroot%\system32;%systemroot%;%systemroot%\system32\wbem;%systemroot %\system32\windowspowershell\v1.0\; C:\Program Files\tortoisesvn\bin;d:\program Files\tortoisesvn0\bin; C:\Program Files\emeditor;%java_home%\bin;%java_home%\jre\bin; C:\Program Files\Microsoft SQL Server\ the\tools\binn\; C:\Program files\dotnet\;%android_home%\tools;%android_home%\platform-tools;%java_home%\bin;%android_home%\ Tools;%android_home%\platform-tools;%android_home%\build-tools\21.1.2;D: \program Files\apache-ant-1.9.9-bin\apache-ant-1.9.9\bin;%gradle_home%\bin;%systemroot%\system32;%systemroot%;%systemroot%\system32\wbem; C:\Users\Administrator.CN-20151209RINA\AppData\Roaming;D:\Program files\nodejs\;%node_path%

Step Three: NPM installation (domestic image installation NPM see article)

Since NPM has been integrated with the new version of Nodejs, NPM has been installed as well. You can also use the cmd command line to enter "Npm-v" to test for successful installation.

The construction of conventional nodejs has been completed so far, so you can enter the "cmd" input "node" into node development mode, enter your Nodejs first sentence: "Hello World"-Input: Console.log (' Hello World ‘)。

Fourth Step: Install the relevant environment

We will first configure the NPM Global Module storage path and the cache path, for example, I would like to put the above two folders in the Nodejs home directory, the Nodejs under the new "Node_global" and "Node_cache" two folder. Such as:

Start cmd, enter:

" D:\Program Files\nodejs\node_global "  "D:\Program files\nodejs\node_cache"

After the command finishes, you can open the "C:\USERS\ADMINISTRATOR.CN-20151209RINA\.NPMRC" file to see if the file was changed successfully, and right-click to open the file with Notepad

So, in fact, modify the path in addition to the cmd command, you can also directly modify the. npmrc file, add the following two lines, the path is changed to its own directory

prefix=D:\Program files\nodejs\node_globalcache=d:\program Files\nodejs\node_cache

Second, remove NPM global path configuration

The method is to delete the "C:\USERS\ADMINISTRATOR.CN-20151209RINA\.NPMRC" file. If the. NPMRC is not in this directory, search globally
