The Reactjs dependency tree could not be resolved

In my current project, I've been attempting to integrate react-tinder-card. After running the command:

npm install --save react-tinder-card

I encountered this error in my console:

npm ERR! code ERESOLVE

Answer №1

$ npm install --save react-tinder-card --legacy-peer-deps

Answer №2

The issue is related to npm version 7.x.

To resolve this, attempt running the command with the --legacy-peer-deps parameter.

Answer №3

Essentially, this error message indicates that the package 

<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="7e0c1b1f1d0a53fc1c3d8cdd0">[email protected]</a>
relies on a peer dependency of react@"^16.8.0". Therefore, it requires this specific version of react to work correctly. However, your 
<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="96e2fff8f2f3e4bbf5faf9f8f3d6a6b8a7b8a6">[email protected]</a>
app is currently using a different version – 
<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="3341565250477302041d031d02">[email protected]</a>
.

To resolve this issue, you can manually install the required react version (in this case, react@"^16.8.0"). This means downgrading your current version in order for the package to run smoothly.

The usage of the --legacy-peer-deps flag was implemented with the release of npm version 7. It allows you to bypass automatic installation of peer dependencies, enabling NPM to proceed with the installation regardless. However, be cautious as this may lead to unexpected outcomes and is not generally recommended.

Answer №4

Encountering this issue typically occurs when attempting to duplicate a project that was originally created a significant time ago, and its dependencies have since been updated to more recent versions.

To resolve this, simply execute the provided code below. I have found this method to work consistently for me. Be sure to review the solution along with the error message.

 npm install --legacy-peer-deps

Answer №5

To resolve the problem, try reverting back to npm version 6.

npm install -g npm@6

Read more about migrating to Apollo Client 3 here

The deprecated react-apollo package is no longer in use, and now all its functions can be accessed directly from @apollo/client:

@apollo/react-hooks -> accessible directly through @apollo/client
@apollo/react-components -> now found in @apollo/client/react/components
@apollo/react-hoc -> now located at @apollo/client/react/hoc
@apollo/react-ssr -> available via @apollo/client/react/ssr
@apollo/react-testing -> accessible through @apollo/client/testing

Answer №7

By reverting back to npm version 6, I was able to successfully resolve the problem.

Answer №8

Encountering a similar issue as mentioned above, I proceeded to update my npm to version 6.7. Following that, I performed a fresh installation of Netlify CMS and Gatsby:

npm install <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="b59b90a1b9999c938c87988d82979899399a888d">[email protected]</a> gatsby-plugin-netlify-cms@^4.0.0

In my static folder, the only item present is a favicon.ico file. There are no admin folders or .yml files in sight.

Answer №9

To overcome dependency conflicts, the following steps can be taken:

  1. Remove the node_modules and package-lock.json files
  2. Execute the necessary command

npm i install

  1. Clean out the npm cache

npm cache clean --force

If the issue persists:

  1. Run the command with --legacy-peer-deps & --force options

npm install --legacy-peer-deps --force

npm install --force

Answer №10

To resolve the problem, consider upgrading to npm version 8.

npm install -g npm@8

Answer №11

To ensure that the dev-dependencies for your React version are correctly installed, opt for using the --force flag rather than the --legacy-peer-deps flag.

Answer №12

You can consider using either --force or --legacy-peer-deps option when running the following command.

npm install react-script-tag --legacy-peer-deps
