node.js - NPM 安装显示错误

问题描述

我试图卸载并重新安装我使用过的 angular cli，

sudo npm uninstall -g @angular/cli
sudo npm install -g @angular/cli

每当我给npm install它显示错误，

npm ERR! Unexpected token < in JSON at position 1 while parsing near '
npm ERR! <!doctype html>
npm ERR! <htm...'

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/izchnl050/.npm/_logs/2018-08-07T08_02_19_674Z-debug.log

日志文件包含以下内容，

基于其他解决方案，尝试以下方法，

npm cache clean --force

卸载节点并再次安装节点但没有用。

如果我给 npm install 它每次都显示上述错误。

npm -v = 6.2.0
node -v = v10.8.0

请帮助我解决此问题并继续工作流程。

解决方案

尝试删除 package.lock 文件

可能的重复 安装错误：位置的 JSON 中的意外令牌 <

package-lock.json is automatically generated for any operations where npm modifies either the node_modules tree, or package.json. It describes the exact tree that was generated, such that subsequent installs are able to generate identical trees, regardless of intermediate dependency updates.

删除 package-lock.json 并在此运行之后npm install。

然后你可以使用 npm 安装任何你想要的插件。
