Install nodejs downgrade

With the development of front-end development, Node.js has become one of the necessary skills for front-end engineers. However, as Node.js versions are constantly updated, downward incompatibilities sometimes occur, causing some older versions of code to fail to run. Therefore, it is sometimes necessary to install an older version of Node.js, a so-called downgrade, to ensure the stability of the code. This article will introduce how to install the old version of Node.js.

Step one: Download the installation package of the old version of Node.js

To install the old version of Node.js, you first need to download the corresponding installation package from the official website. On the historical version page of the website, we can find the installation packages of previous versions of Node.js, as shown below:

sudo apt-get install build-essential libssl-dev

Then, use the following command in the terminal to install the downloaded old version of Node.js:

sudo dpkg -i /path/to/node-vX.X.X-linux-x64.tar.gz

After the installation is complete, we can detect it through the following command Node.js version number:

node -v

If the expected version number appears, then the downgrade installation is successful.

Summary:

It is not difficult to downgrade and install Node.js. You only need to download the installation package of the corresponding version, uninstall the current version, and install the old version. However, it should be noted that downgrading may cause some functions to become invalid and some dependent libraries to be unavailable. Therefore, before downgrading the installation, you need to confirm whether your code is compatible with the old version and whether the dependent libraries are updated.
