pip3:tldr:da2f3
The command pip3 install --requirement ${requirements-txt}
is used to install packages listed in a requirements file.
Here's a breakdown of the command components:
-
pip3
: This is the command-line program used to install Python packages.pip3
is a package installer for Python 3.x versions. -
install
: This is a subcommand forpip3
that is used to install Python packages. -
--requirement
: This is a flag used to specify a requirements file that contains a list of packages to be installed. Instead of specifying individual packages one by one, using a requirements file is a convenient way to install multiple packages with their respective versions. -
${requirements-txt}
: This is a placeholder for the actual name of the requirements file. The${}
syntax suggests that it's a variable that should be replaced with the appropriate value. In this case, the variable likely represents the name of the requirements file (e.g.,requirements.txt
).
To use this command, you need to replace ${requirements-txt}
with the actual name and path of the requirements file you want to install packages from. For example, if your requirements file is named my-requirements.txt
and located in the current directory, the command would be: pip3 install --requirement my-requirements.txt
