#How to set up pycharm for python projects install
So we need to remove those specific unnecessary dependencies manually so they don’t create any issues when we install using requirements.txt python_package1=1.0įutures=1.0 # specific to python_package1 Scenario – Sometimes when developers try with different libraries for experiment, but they tend to forget to remove from the project, but those libraries left inside the requirements.txt file, so when other developer use the requirements.txt to install the packages might not have idea where it’s used inside the project.Īnother scenario – few libraries when we install, requirements.txt add extra dependencies specific to the libraries, but when we upgrade the libraries during course of time, the dependencies might not be required, but doesn’t remove from the requirements.txt Sometimes handcraft or relook into the requirements.txt is a good idea after doing a pip freeze why? This will keep all the installed package names with the versions installed for the current project. Navigate to your project directory in terminal & type So requirements.txt file will automatically updates the package details with version when someone installs a new package, also python provides a way to install those version packages directly from the requirements.txt file, so you need not to manually install each & every package. When a person is working on a python project and added some python libraries and then shares the project in the team or when a new team member joins the team, it’s always difficult to tell what libraries used in the project, either you have to specify in a text document or write somewhere.īut during the time, if you upgrade the libraries, you have to manually update the version details as well in the documentation, so the next person who picks up the project can install specific version of the libraries.
