npm审核修复后找不到模块“ date-fns”

Question

My react app was working fine until I ran npm audit fix . I am now getting an error:

Test suite failed to run

Cannot find module 'date-fns/addDays' from 'date-fns-utils.js'

However, Jest was able to find:
        './index.css'
        './index.js'
        './index.test.js'

You might want to include a file extension in your import, or update your 'moduleFileExtensions', which is currently 
['web.js', 'js', 'web.ts', 'ts', 'web.tsx', 'tsx', 'json', 'web.jsx', 'jsx', 'node'].

On one of the tests during npm test

What could this be? Let me know what details I need to add. Thanks!

Answer 1

我建议您删除：node_modules和package-lock.json并运行npm install。

Answer 2

Maybe you could try explicitly downloading the date-fns library and seeing if this gets rid of your current error message of:

Cannot find module 'date-fns/addDays' from 'date-fns-utils.js'

which indicates that the issue is due to being unable to locate the addDays module within the date-fns package. I suspect npm audit fix may have had an issue installing the more up-to-date version of the date-fns library.

Perhaps you could try the following and seeing if this resolves your issue:

rm package-lock.json
npm i -S date-fns 

# or with yarn
yarn add date-fns

Hopefully that helps!
