It will make your life a lot simpler. Installing, Uninstalling and Upgrading Packages PyCharm provides methods for installing, uninstalling, and upgrading Python packages for a particular Python interpreter. To manage Python packages, open the page of the project settings, select the desired Python interpreter or virtual environment. If you select a Python SDK with the configured Conda environment, the Use Conda Package Manager toggle appears in the packages area toolbar. Use this toggle to manage packages from the Conda environment repository. By default, this toggle is switched off and you can manage only the packages available with the selected Python interpreter. To install a package • Click Install ( ). • In the dialog box that opens, preview the list of the available packages. By default, the latest version is taken. • Options: If this checkbox is selected, you can type the options in the text field. • Install to user's site packages directory: If this checkbox is left cleared (by default), then the packages will be installed into the current interpreter package directory. If the checkbox is selected, the packages will be installed into the specified directory. This option is not available for Conda environments. • Select the target package and click Install Package.

PyCharm smartly tracks the status of packages and recognizes outdated versions by showing the number of the currently installed package version (column Version), and the latest available version (column Latest version). When a newer version of a package is detected, PyCharm marks it with the arrow sign and suggests to upgrade it. By default, column Latest version shows only stable versions of the packages. If you want to extend the scope of the latest available versions to any pre-release versions (such as beta or release candidate), click Show early releases. To upgrade a package • In the list of the packages, select the package to be upgraded. • Click Upgrade ( ). Note that clicking Apply doesn't lead to package upgrading. This button only utilizes all performed package changes. The selected packages are upgraded to the latest available versions. You can upgrade several packages at once. Hold Cmd (macOS) or Ctrl on (Unix or Windows), left-click to select several items in the list of packages, and then click Upgrade.
