Updating Angular CLI

To update Angular CLI to a new version, you must update both the global package and your project‘s local package.

Global package:

npm uninstall -g @angular/cli  
npm cache clean  
# if npm version is > 5 then use `npm cache verify` to avoid errors (or to avoid using --force)  
npm install -g @angular/cli@latest

Local project package:

# use rmdir /S/Q node_modules dist in Windows Command Prompt;  
# use rm -r -fo node_modules,dist in Windows PowerShell  
rm -rf node_modules dist  
npm install --save-dev @angular/cli@latest  
npm install 
 

一次升級 package.json的所有版本

需使用npm-check-updates工具
# 安裝npm-check-updates
npm i -g npm-check-updates
# 升級
ncu -u
# 安裝新版本
npm install

運行npm ls可查看版本是否匹配。
運行npm view \<package>可查看某一package發布的版本，如:
npm view ngx-bootstrap [versions]
進入package目錄下，運行npm version可查看安裝的版本。

package.json中的version語法請參見The semantic versioner for npm

搭建NPM私服

推薦使用Nexus，概念和配置方法同Maven私服一致，分為proxy、hosted、group三類。
創建proxy如下：

Remote URL: https://registry.npmjs.org
然後創建hosted、group，不再贅述。
最後在home下創建.npmrc文件，其內填寫public地址，如下：
registry=http://localhost:8081/repository/npm-public/

Cannot find module ‘node-sass‘

npm install node-sass --no-bin-links
