Question
I have tried to uninstall and reinstall angular cli, for which i have used,
sudo npm uninstall -g @angular/cli
sudo npm install -g @angular/cli
Whenever i give npm install it is showing the error,
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
And the log file consists the following,

Based on the other solutions, tried with the following,
npm cache clean --force
Uninstalled node and again installed node but there is no use.
If i give npm install it showing the above error everytime.
npm -v = 6.2.0
node -v = v10.8.0
Kindly help me to fix this issue and to continue with the workflow.

try to remove package.lock file
Possible duplicate 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.
Delete the package-lock.json and after this run npm install .
Then you can install any plugin, that you want, with npm.
