1. Download the installation package from the official website address
https://nodejs.org/zh-cn/download/
Select the node.js version corresponding to your project or system. I am using the latest version, Windows, 64-bit.
If you want to download a specified version, click [Previous Versions] to select the version you want to download
2. Installer
(1) After the download is complete, double-click the installation package to start installing Node.js
(2) Click the [Next] button directly, here you can modify the installation path according to your personal needs, and continue to click the [Next] button after the modification
(3) It can be done according to your own needs. Here I choose the default installation, and continue to click the [Next] button
(4) Not selected, click the [Next] button directly
(5) Click the [Install] button to install
(6) After the installation is complete, click the [Finish] button
(7) To test whether the installation is successful, press the [win+R] key, enter cmd, and open the cmd window
Input: node -v // Display node.js version
npm -v // display npm version
--Successfully display the version description and install successfully
3. Environment configuration
(1) Find the installation directory, and create two new folders [node_global] and [node_cache] under the installation directory
(2) After the creation is complete, open the cmd command window as an administrator (see Tips below for the opening method), and enter
①npm config set prefix "your path\node_global" (copy the "node_global" folder path you just created)
npm config set prefix "G:\node\nodejs\node_global"②npm config set cache "your path\node_cache" (copy the "node_cache" folder path you just created)
npm config set cache "G:\node\nodejs\node_cache"Tips: How to run cmd as an administrator: Click the [Start] menu in the lower left corner, enter " command prompt " in the search area, and then click [Run as administrator]
=============== Or click the right mouse button and select [Run as Administrator] ========================= ===
(3) Configure environment variables
①【This Computer】-Right click-【Properties】-【Advanced System Settings】-【Environment Variables】
② Click [New] in [System Variables]
1) Variable name: NODE_PATH
Variable value: C:\Program Files\nodejs\node_global\node_modules
(The value of this variable is the location of your own installation file, modify the location information before node_global according to your storage location)
Then you will find a [node_modules] folder in [node_global]
Tips: If the [node_modules] folder is not automatically created after entering the variable value, manually create a [node_modules] folder under [node_global] , and then copy the path address of the [node_modules] folder you created to the variable value.
③ Edit [Path] in [User Variables]
④ Change the default [ ] under the C drive AppData\Roaming\npm to [ ] node_global】的路径, and click OK
⑤ Select [Path] in [System Variables], click [Edit] to add [NODE_PATH], and then keep clicking [OK]
4. Test
After the configuration is complete, install one of the most commonly used express modules globally for testing
npm install express -g // -g代表全局安装
When the following interface appears, the configuration is successful
Tips: If the installation fails, it may be that you did not run the cmd window as an administrator, or you can modify the permissions of [node_global] and [node_cache]
Steps: Right-click the [node_global] folder, click [Properties], then click [Security], then click [Edit], check all the permissions, and then click [OK], and the steps for [node_cache] are the same.
