Node.js 版本控制

怎么管理Node的版本阿

这里记录下来一些尝试避免电脑环境大寄

尝试前初始状态

本机电脑Node.js版本为20.17.0

安装目录为D:\CodeSoftware\Node.js

npm版本为10.8.2

目录为npm@10.8.2 D:\CodeSoftware\Node.js\node_modules\npm

Node.js环境变量设置为D:\CodeSoftware\Node.js 为系统环境变量，这里存放npm指令的地址

npm缓存目录为C:\Users\藤爬\AppData\Local\npm-cache

这个可以使用

npm config get cache

获得

这个没有加入环境变量中, 可以使用npm config set cache "C:\Users\藤爬\AppData\Local\npm-cache"设置

npm全局目录为C:\Users\藤爬\AppData\Roaming\npm

这个可以使用

npm config get prefix

获得

这个被加入到了用户变量中, 可以使用npm config set prefix "C:\Users\藤爬\AppData\Roaming\npm"设置npm的全局目录，在电脑环境变量中更改调用的环境变量

没有设置的几个变量还有

Node.js的node_modules地址，可以加入到系统变量中

对于新存放的目录，要设置权限，右击Node.js文件夹，依次点击属性``安全点击编辑然后全部允许

电脑里面有两个存放了node_modules的文件夹

• C:\Users\藤爬\node_modules
• D:\CodeSoftware\Node.js\node_modules\npm\node_modules
• C:\Users\藤爬\AppData\Roaming\npm\node_modules
  全局的应该在C:\Users\藤爬\AppData\Roaming\npm\node_modules
  C:\Users\藤爬\node_modules是以C:\Users\藤爬为项目目录的node包目录

node/npm相关配置文件有

• “C:\Users\藤爬.node_repl_history”
• “C:\Users\藤爬\package-lock.json”
• “C:\Users\藤爬\package.json”
• “C:\Users\藤爬.yarnrc”
• “C:\Users\藤爬.npmrc”

Node相关环境内置变量
Environment variables:
FORCE_COLOR when set to ‘true’, 1, 2, 3, or an empty string
causes NO_COLOR and NODE_DISABLE_COLORS to be
