In our next Terminal tip, we'll show you how to download files from the web. Of course it's probably easier just to use the GUI of Safari, but using Terminal gives you additional stats like file. We recommend using an user install, sending the -user flag to pip. Pip installs packages for the local user and does not write to the system directories. Preferably, do not use sudo pip, as this combination can cause problems. Pip accesses the Python Package Index, PyPI, which stores almost 200,000 projects and all previous releases of said projects. Because the repository keeps previous.
PyCharm provides methods for installing, uninstalling, and upgrading Python packages for a particular Python interpreter. By default, PyCharm uses pip to manage project packages. For Conda environments you can use the conda package manager.
To manage Python packages for the Python interpreter, select the Python Interpreter page in the project Settings/Preferences or select Interpreter Settings in the Python Interpreter widget.
If you select a Python interpreter 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.
Install a package
If you've got any or error messages, consult the Troubleshooting guide for a solution.
Uninstall a 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PyCharm smartly tracks the status of packages and recognizes outdated versions by showing the number of the currently installed package version (column Version), and the latest available version (column Latest version).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, the Latest version column 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.
Upgrade a package
How To Install Numpy Windows
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.
If you're accustomed to installing packages from the commands line, you can proceed with your workflow using the Terminal.
Reuse installed packages
If you are managing Python packages (libraries) with pip, you can use the configuration file
requirements.txt to install the specified packages with the specified version at once.
Here, the following contents will be described.
![]()
Install multiple packages with pip: -r requirements.txt
The following command will install the packages according to the configuration file
requirements.txt .
The name of the configuration file is arbitrary but the name
requirements.txt is often used.
Put
requirements.txt in the directory where the command will be executed. If it is in another directory, specify the path.
How to write configuration file 'requirements.txt'
An example of configuration file
requirements.txt is as follows.
Like Python code, you can write comments using
# .
You can specify the version with ,
> , >= , < , <= , etc. If the version is omitted, the latest version is installed.
Two conditions can be specified with AND by separating them with a comma
, . In the following example, a version of 1.0 or more and2.0 or less is installed.
Export current environment configuration file: pip freezepip freeze outputs the package and version installed in the current environment in the form of a configuration file that can be used with pip install -r .
![]()
If you output
pip freeze to a file with redirect > , you can use that file to install packages of the same version as the original environment in another environment.
