推荐答案

Try:-

从 npm@5 开始，npm 缓存会从损坏问题中自我修复，并且保证从缓存中提取的数据是有效的.如果您想确保一切都一致，请改用npm cache verify".如果您确定要删除整个缓存，请使用 --force 重新运行此命令.

Try:-

As of npm@5, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid. If you want to make sure everything is consistent, use 'npm cache verify' instead. If you're sure you want to delete the entire cache, rerun this command with --force.

步骤 1)

$ npm cache clean --force

或

$ npm cache verify

步骤 2)

$ npm install -g @angular/cli@latest

或

尝试卸载和安装 angular/cli

步骤 3)

$ npm install --save-dev @angular/cli@latest

步骤 4)

删除node_modules并运行$ npm install
