Pip でrequirements.txt を使用してローカル ディレクトリからパッケージをインストールする方法

Installing Packages from Local Directory Using requirements.txt with Pip

In order to install packages using pip according to the requirements.txt file from a local directory, you can utilize the -r option. This option allows you to specify a requirements file that contains a list of packages and their dependencies. The syntax for using this option is as follows:

pip install -r /path/to/requirements.txt

In your case, the requirements file is located at /path/to/requirements.txt. However, you are also trying to install the packages from a local archive directory using the -f option. This is not necessary as the -r option will automatically install the packages from the specified location.

To correct the issue, simply remove the -f option from the command:

source bin/activate
pip install -r /path/to/requirements.txt

This will install the packages according to the requirements.txt file from the local archive directory. You can then verify that the packages are installed properly by importing them into your code or checking the site-packages directory of your virtualenv.
