We also need to make sure that the program is executed correctly in different environments. Thus, we need some kind of configuration file that manages the requirements in an organized way.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is pipenv?<\/h2>\n\n\n\n<p><strong>Pipenv<\/strong> is the recommended way to install Python packages and use a <a href=\"https:\/\/www.askpython.com\/python\/examples\/virtual-environments-in-python\" data-type=\"post\" data-id=\"11337\">virtual environment<\/a>. This is because when we use the pip package manager that\u2019s bundled with Python, all packages are installed globally. <\/p>\n\n\n\n<p>We don\u2019t have encapsulated environments for our Python projects like creating web apps with <strong><a href=\"https:\/\/www.askpython.com\/django\/django-model-forms\" data-type=\"post\" data-id=\"8009\">Django<\/a><\/strong>, <strong><a href=\"https:\/\/www.askpython.com\/python-modules\/flask\/flask-crud-application\" data-type=\"post\" data-id=\"8892\">Flask<\/a><\/strong> or some other machine learning project. <\/p>\n\n\n\n<p>Pipenv allows us to isolate the packages in specific environments. <\/p>\n\n\n\n<p>Conventionally, programmers create a virtual environment and install packages inside it with pip. But pipenv automatically creates and manages a virtual environment and allows us to <em>add and remove packages<\/em> using a <strong>Pip<\/strong> <strong>file<\/strong> which is similar to various <strong>package managers<\/strong> like <strong>npm, yarn, composer,<\/strong> etc.<\/p>\n\n\n\n<p>It also generates the ever-important <strong>Pipfile.lock<\/strong>. This is used to produce a deterministic build which means that for each specific project, the same version of packages that are listed in the <strong>Pip File <\/strong>will be used for that specific project. <\/p>\n\n\n\n<p>There are no breaking changes if the project runs in any other place like in the production environment OR on a cloud OR a different machine.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Some common issues that pipenv seeks to solve<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>We no longer have to use pip and virtualenv separately.<\/li><li><strong>requirements.txt<\/strong> file, was cumbersome to manage and also error-prone in some cases. <strong>Pipfile<\/strong> and <strong>Pipfile.lock <\/strong>used by pipenv is more user-friendly, easily managed, and mitigates errors.<\/li><li>Pipenv exposes the security vulnerabilities automatically and on top of that, <strong>hashed values<\/strong> are used everywhere by pipenv.<\/li><li>It provides insight into our dependency graph for all the packages.<\/li><li>Streamlines the dev workflow by loading .env files.<\/li><li>It also encourages making use of the latest versions of dependencies to minimize the security risks arising from outdated components.<\/li><\/ul>\n\n\n\n<p><strong><em>Also Read<\/em><\/strong>: <strong><a href=\"https:\/\/www.askpython.com\/python\/conda-vs-pip\" target=\"_blank\" rel=\"noreferrer noopener\"><em>Conda vs Pip: Choosing your Python package manager<\/em><\/a><\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Working with pipenv<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>Install pipenv using the <a href=\"https:\/\/www.askpython.com\/python-modules\/python-pip\" data-type=\"post\" data-id=\"3848\">pip command<\/a>:<\/li><\/ul>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\npip install pipenv\n<\/pre><\/div>\n\n\n<h3 class=\"wp-block-heading\">Look for all the packages using pip<\/h3>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: plain; title: ; notranslate\" title=\"\">\npip freeze\n<\/pre><\/div>\n\n\n<p><strong>Output:<\/strong><\/p>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: plain; title: ; notranslate\" title=\"\">\ncertifi==2022.6.15\ndistlib==0.3.5\nfilelock==3.7.1        \npep8==1.7.1\npipenv==2022.8.5       \nplatformdirs==2.5.2    \nPySimpleGUI==4.60.3    \nvirtualenv==20.16.3    \nvirtualenv-clone==0.5.7\n<\/pre><\/div>\n\n\n<h3 class=\"wp-block-heading\">Create and activate a virtual environment using pipenv<\/h3>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\npipenv shell\n<\/pre><\/div>\n\n\n<p>This creates a <strong>Pipfile<\/strong> that contains all our dependencies.
