Prerequisites for Uninstallation
Before proceeding with the uninstallation, ensure you have the necessary permissions to modify or remove software on your system. This may require administrative access, especially on operating systems like Windows or macOS. Additionally, it is advisable to check if any projects currently depend on pnpm. Backing up any important data or configurations may also be wise, as uninstallation could affect your development environment.
Uninstalling Pnpm Globally
To uninstall pnpm globally, you can use the npm package manager. If pnpm was installed globally, the following command will remove it from your system:
npm uninstall -g pnpm
This command tells npm to uninstall the pnpm package from the global scope, effectively removing the global pnpm command from your command line interface. After this command executes, pnpm will no longer be available for global usage.
Using Npm to Remove Pnpm
For systems where pnpm was installed using npm, the uninstallation process remains similar. To remove pnpm via npm, run the following command in your terminal:
npm uninstall pnpm
This command targets the local project directory and removes pnpm from the node_modules folder, along with any associated files in the package.json. After executing this command, pnpm will no longer be part of your project's dependencies.

Executing the Pnpm Uninstall Command
Sometimes, users might want to uninstall pnpm using its own command. While pnpm does not have a specific uninstall command like npm, it’s crucial to remove the pnpm-related directories to ensure a clean uninstall. You can locate the pnpm installation directory by running:
pnpm root -g
This command will provide the directory where pnpm is installed globally. After identifying this directory, manually delete it to remove all pnpm files.
Handling Pnpm Dependencies
If you have projects that rely on pnpm, consider the potential impact of uninstallation on these projects. Projects using pnpm as the package manager may not function correctly after its removal. If you plan to switch to another package manager, ensure to update your package.json file accordingly. This involves changing the package manager field to reflect the new manager you intend to use, such as npm or yarn.
Checking Pnpm Version Before Removal
Prior to uninstallation, it may be beneficial to check your current pnpm version. This can help confirm that you are indeed removing the correct version. To check the installed version, run:
pnpm -v
This command will display the version of pnpm currently installed. Knowing the version can be helpful for referencing specific features or bugs related to that version later.
Cleaning Up Pnpm Cache
After uninstalling pnpm, it is advisable to clean up any remaining cache that pnpm may have created during its usage. Caches can take up unnecessary disk space and might lead to confusion if you decide to reinstall pnpm later. To remove the pnpm cache, execute the following command:
pnpm store prune
This command removes unnecessary files from the pnpm store, ensuring a clean state. If pnpm is already uninstalled and you still want to clean up the cache, you may need to manually delete the cache directory, typically located in your home directory under .pnpm-store.

Verifying Pnpm Uninstallation
Once you have completed the uninstallation process, verifying that pnpm has been successfully removed is crucial. This can be done by trying to run the pnpm command in your terminal:
pnpm -v
If pnpm has been successfully uninstalled, you should see an error message indicating that the command is not recognized. This confirms that the pnpm command is no longer available on your system.
Reinstalling Pnpm After Uninstallation
Should you decide to reinstall pnpm after its uninstallation, the process is simple and can be carried out using npm or other package managers. To reinstall pnpm globally, run the following command:
npm install -g pnpm
This command will download and install the latest version of pnpm globally on your system. After installation, you can verify the installation by checking the version again:
pnpm -v
This will confirm that pnpm has been successfully reinstalled, allowing you to resume using it for your package management needs.
