Errors of Unexpected token in JSON at position XXX while parsing near

Question

I npm install on a directory with a package.json for my company project. However, it keeps giving me various errors of Unexpected token in JSON at position....

I have done npm cache clean --force, npm cache verify etc. as suggested by When I run `npm install`, it returns with `ERR! code EINTEGRITY` (npm 5.3.0)

However, the issue still persists. I do not configure proxy though as my machine is not on any corporate proxy.

Anyway, I attach the npm log content and package.json file content for your reference. Please kindly help to advise me what's wrong and how to resolve this issue.

I also added the output for npm config and npm config ls -l below.

I found .npmrc in /usr/lib/node_modules/npm and it is empty.

I found npmrc in /usr/local/lib/node_modules/npm and its content:

globalconfig=/etc/npmrc
globalignorefile=/etc/npmignore
prefix=/usr/local

Do you find anything odd from the contents above? I read npm-config and npmrc but can't find anything helpful.

Thanks.

Answer 1

I had the same error, I deleted my package-lock.json file and my node_module folder and it worked.
