** Ethereum: The addiction of the Library of the Library

As a developer working on customized decentralized applications (DAPP), it is not uncommon for problems with library addictions. One of the widespread problems that may arise is the mismatch between the libraries of the foundation and the addictions that your DAPP is needed.

In this article, we will study the problem you are experiencing with the periphery/core of Openzeppelin V4 and UNISWAPV3, two essential components of your project. We will also discuss how to resolve this addiction mismatch using the management tools of the Library of the Fund.

Question

When you installed the UNISWAPV3 peripheral/core in your project, it introduced a new library dependence on Openzeppelin V4. However, Openzeppelin V4 is no longer supported by the project maintainers due to changes in security vulnerabilities and its basic functions.

As a result, when trying to import the Openzeppelin V4 libraries to your DAPP, you are facing errors and warnings from the tools of the foundation. This mismatch can cause your code failure to compile or run in unstable position.

Solution

Follow these steps to resolve this addiction mismatch:

1
Check your addictions : Run a “npm lsor" yarn list "to make sure all the necessary libraries are installed correctly.

bash

NPM Install -Save @Openzeppelin/Contracts

`

Alternatively, you can use the yarn Add with option ‘-for-standard’ to force you to install the latest version:

`bash

yarn add @Openzeppelin/contract-for-standard

`

3
Update the UNISWAPV3 peripheral/kernel : Run npm uninstall or yarn remove 'to remove the outdated Uniswapv3 peripheral/nucleus addiction, and then install the new version using NPM or Yarn:

bash

NPM Uniswap-V3-Peripheria/Core

NPM Install-Save @Uniswap/V3-Pereration

`

Alternatively, you can use yarn add with option-for-standard:

`bash

yarn add @uniswap/v3-peri-perceru-power standard

`

• Update Openzeppelin V4 Libraries : After the addiction update, including Openzeppelin V4, run to install “NPM installation” or “yarn installation” to update all the affected libraries.

Best Practice

To eliminate this issue in the future:

• Check library updates and maintains regularly.

• Use the Foundry’s built -in addiction management tools to provide accurate versions of the library.

• Check your DAPP carefully after updating your addictions to catch all the problems early.

When performing these steps, you should be able to resolve the mismatch of the addiction of the foundation library caused by the periphery/core of the Openzeppelin V4 and UNISWAPV3. Happy encoding!
