“No Module Named Crypto” Error And Its Solution

Python has a large number of current libraries, such as NumPy, pandas, sklearn, and others, that allow developers to quickly execute complicated operations. The “PyCrypto” module, which has since been superseded by “PyCryptodome,” is used for cryptography and security engineering.

In order to use this module in Python, you must first import it. If the “PyCrypto” module is imported without being installed, the “ModuleNotFoundError” error occurs in Python. With the following contents, this article will illustrate the cause and remedies for the “no module called Crypto” problem.

The principal cause of this “ModuleNotFoundError” in Python is when a user imports the “Crypto” module without first installing it. This problem also happens when we use the name “Crypto” for modules such as “Crypto.py” or when we use the name “Crypto” to initialize a variable.

Solution for Windows Operating Systems

Installing the module in Python is the best solution to overcome this problem. The “pip” package manager is used to install the module. The pip module is included with Python; if you don’t have one, you can get one by following this tutorial. You may use the following procedures to install the “Crypto” module:

  1. Launch CMD: Just hit the “Windows key + R” button and type “cmd” into the run dialog box to open the command prompt terminal. If you are using a virtual environment in the Python editor, it is best to launch the editor shell instead of cmd and install the module on the IDE terminal.
  2. Install the ‘Crypto’ Module  Using pip: To install the “Crypto” module using “pip,” use the following line: > pip install pycryptodome – if you receive a permissions error, use the following command: > pip install pycryptodome —user
  3. Verification of ‘Crypto’ Module in Python:  To check the installation of the “Crypto” module in Python, type: > pip show pycryptodome
