当创建一个新的Angular 5项目时:
节点版本号:8.9.2
NPM版本:5.5.1
我的命令是:
npm install -g @angular/cli
错误是:
npm ERR! **Unexpected end of JSON input while parsing near '...nt-webpack-plugin":"0'**
npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\Aashitec\AppData\Roaming\npm-cache\_logs\2017-12-06T13_10_10_729Z-debug.log

这个错误可能是由许多不同的原因引起的。也许你的全局包以某种方式损坏了，我建议执行以下操作。
1 Install Node Version Manager (or NVM for Windows) and install Node version 10.16.1. This is enough for angular 9 and from my experience, it is the most stable version for development. This should also change your NPM version so that may also help.
2 Uninstall global angular package npm uninstall -g @angular/cli
3 Force clear cache npm cache clean --force
4 You can also try clearing your %temp% and %roaming% AppData/npm-cache
5 install latest angular package npm install -g @angular/cli@<your-version>
6 if this error still occurs, consider using another shell.

这里的30个答案都不适合我。我需要:
删除node_modules和package-lock.json NPM缓存清理——force NPM install -g @angular/cli NPM I——仅包锁 npm ci
唷!
我用
npm cache clean --force
然后更新NPM
npm i npm@latest -g
然后通常使用NPM安装命令
npm install

这为我解决了问题:
以管理员身份打开Windows Powershell
npm cache clean --force
npm install -g @angular/cli

错误:npm ERR!解析JSON输入时意外结束“…ore-js”:“3.0.0-beta.1 .
这发生在全局安装expo CLI时，这对我有用!
npm cache clean --force
