Qu'est-ce que you need to install jmespath prior to running json_query filter ?

"You need to install jmespath prior to running json_query filter" is an instruction or warning message that typically appears in the context of working with JSON data and the jmespath library or filter.

In Python and other programming languages, jmespath is a query language and library specifically designed for working with JSON data. It allows you to extract and transform data from JSON documents easily. Many frameworks and tools use jmespath for querying and manipulating JSON.

When you encounter the message "You need to install jmespath prior to running json_query filter," it means that the code or script you are running requires jmespath to be installed on your system or environment in order to use the json_query filter.

To resolve this issue, you need to install jmespath using a package manager or a command-line tool, depending on your programming language or platform. Here are a few common examples:

1. Python: You can use pip, the Python package manager, to install jmespath. Run the following command in your terminal or command prompt:

   pip install jmespath
   

2. Node.js: You can use npm, the Node.js package manager, to install jmespath. Run the following command in your terminal or command prompt:

   npm install jmespath
   

Once you have installed jmespath, you can then proceed to run the code or script that requires the json_query filter. The warning message should no longer appear, and you will be able to use jmespath to query and manipulate JSON data according to the syntax and functionalities it provides.
