In Python,.whlFiles (also known as wheel files) are binary package formats that allow users to install Python libraries without source code. This is very useful for users who do not have a compiled environment or want to install it quickly. In this article, we will explore how to install locally.whldocument.
1. Download the .whl file
First, you need to download from a trusted source.whldocument. This can be from the official Python websiteFilesPart of it can also be a third-party library hosting platform like PyPI. Make sure you download files that are compatible with your Python version and operating system.
2. Install pip
If you haven't installed pip yet, you need to install it first. pip is a package manager for Python, used to install and manage Python libraries. You can download the script through the official Python website and follow the instructions to install it.
3. Use pip to install the .whl file
Once you have it.whlFiles and pips, you can install it using the following command:
pip install /path/to/your/
In the above command, you need to/path/to/your/Replace with yours.whlThe actual path to the file. For example, if your.whlThe file is located in your user directoryDownloadsIn the folder, and the file name isexample-package-1.0., then you should run the following command:
pip install ~/Downloads/example-package-1.0.
4. Verify installation
After the installation is complete, you can verify that the library has been successfully installed through Python's interactive interpreter. Open the terminal and enterpythonorpython3(depending on your Python environment configuration) to start the Python interpreter and try to import the library you just installed:
import example_package
If no error occurs, it means that the library has been installed successfully and can be used normally.
5. Things to note
- Make sure your pip version is up to date in order to support the latest wheel formats and features. You can use
pip install --upgrade pipCommand to update pip. - If you encounter permission issues during installation, you can try adding it before the command
sudo(on Linux or macOS) or use a virtual environment to avoid permission issues. - If you are using a virtual environment, make sure you have activated the corresponding virtual environment before running the installation command.
Through the above steps, you should be able to successfully install locally.whlfile and use it in Python. Whether it is to quickly deploy the project or to avoid the hassle of compiling the source code,.whlFiles are a very practical tool.
Attachment: Uninstall the local Python package
If you want to uninstall the installed local package, you can use the uninstall option of the pip command. In a command prompt or terminal, execute the following command:
pip uninstall numpy
Most of the time, even if you install the package manually through the wheel file, pip will add it to the list it manages. So you can try uninstalling it using pip's uninstall command, just like uninstall any other package installed via pip.
However, if you are sure that PIP doesn't know about this package (probably not registered correctly for some reason), or if you want to make sure the uninstall process is more straightforward, you can try the following steps:
Check whether the package is installed through pip:
pip show numpy
First, try to use the list or show command of pip to see if the package is installed and get its information. If this command returns the information of the package, then you can use the uninstall command to uninstall it.
If pip show numpy returns no information, then pip may not know about this package. This is usually unlikely, as packages installed through wheel files are usually registered by pip. However, if this does happen, you can try manually deleting the package file and finding the directory where the package file is located. For Windows, this is usually Python's Lib\site-packages directory, but if you use a virtual environment, it will navigate to that directory at the corresponding location in your virtual environment directory, and look for basemap-related files and folders. There will be a folder named numpy and/or some .pyd, .pyc, .pyo and other files starting with numpy, and delete these files and folders;
