Question

我尝试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

每当我进行 npm安装时，它就会显示错误，

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，请尝试以下操作

npm cache clean --force

未安装的节点，然后又是已安装的节点，但是没有用。

如果我给npm安装，每次都会显示上述错误。

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

请帮助我解决此问题并继续进行工作流程。

Answer 1

尝试删除package.lock文件

可能重复的Install error: Unexpected token < in JSON at position

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，然后运行npm install。

然后，您可以使用npm安装任何所需的插件。

NPM安装显示错误
