If you are a Node.js developer, you might have encountered an error message that says 'node: --openssl-legacy-provider is not allowed in node_options'. This error message can be quite confusing for new developers or even experienced ones. In this guide, we will explain what causes this error and provide a step-by-step solution to help you fix it.
What Causes the Error: 'node: --openssl-legacy-provider is not allowed in node_options'?
This error message usually appears when you are using Node.js with an older version of OpenSSL. OpenSSL is a library that provides encryption and decryption functions that are used by Node.js. When you run Node.js, it uses OpenSSL to encrypt and decrypt data. However, if you are using an older version of OpenSSL that does not support the '--openssl-legacy-provider' option, you will get this error message.
How to Fix the Error: 'node: --openssl-legacy-provider is not allowed in node_options'
To fix this error, you need to update your OpenSSL library to a version that supports the '--openssl-legacy-provider' option. Follow these steps to update your OpenSSL library:
First, check your current version of OpenSSL by running the command openssl version. This will give you the version number of your OpenSSL library.
Go to the OpenSSL website (https://www.openssl.org/) and download the latest version of OpenSSL that supports the '--openssl-legacy-provider' option. Make sure to download the correct version for your operating system.
Install the new version of OpenSSL on your system. Follow the instructions provided by the OpenSSL website to install it correctly.
Once you have installed the new version of OpenSSL, run the command openssl version again to verify that the installation was successful.
Finally, run your Node.js application again. The error message should no longer appear, and your application should run as expected.
