This article mainly explains "how to install third-party modules in a variety of environments in Python3". The explanation in this article is simple and clear and easy to learn and understand. Please follow the editor's train of thought to study and learn how to install third-party modules in a variety of Python3 environments.

The method of installing third Party Module in multiple environments of Python3

Python in addition to its own standard library, other developers have written some of their own modules, called third-party modules, third-party modules further expand the functions of Python. The main way to install third-party modules is to use Python's pip tool. Third-party modules for Python can be securely downloaded from https://pypi.python.org/.

The executable file of the pip tool is called pip on Windows and pip3 on OS X and Linux. On Windows and OS X, pip is automatically installed with Python, but on Linux, it must be installed separately, on Windows, under the scripts directory of the installation directory, on OS X, and under the bin directory of the installation directory. To install pip3 on Linux, simply open a new terminal window and type get install Python3-pip or install Python3-pip.

To install a third-party module using pip, you need to run the pip tool on the command line, and then enter the install command to keep up with the name of the module you want to install. For example, on Windows, enter pip install ModuleName,ModuleName as the name of the module, the same below. On OS X or Linux, you must use the sudo prefix to run pip3, which requires administrator privileges to install the module, such as sudo pip3 install ModuleName.

If you want to upgrade installed modules to the latest version, run pip install-U ModuleName (or run pip3 install-U ModuleName on OS X and Linux). After installing the module, you can run import ModuleName in an interactive environment to test the success of the installation. If you want to display an error message, you can assume that the module has been successfully installed.

Example: the method of installing third-party module pyperclip and updating pip under Windows.

C:\ Users\ Administrator > pip install pyperclip

Collecting pyperclip

Downloading https://files.pythonhosted.org/packages/33/15/f3c29b381815ae75e275

Installing collected packages: pyperclip

Running setup.py install for pyperclip... Done

Successfully installed pyperclip-1.6.2

You are using pip version 9.0.3, however version 10.0.1 is available.

You should consider upgrading via the 'python-m pip install-upgrade pip' comm

And.

If the pip version is too old, enter python-m pip install-- upgrade pip to upgrade the pip version. There is no upgrade here, depending on the situation.

C:\ Users\ Administrator > python-m pip install-- upgrade pip
