![]() Second, click “ Show Context Actions” in your context menu. You can see this in this screenshot from the docs: In our case, the ModuleNotFoundError is a subclass of the ImportError class. Python defines an error hierarchy, so some error classes inherit from other error classes. What’s the difference between ImportError and ModuleNotFoundError? What’s the Difference Between ImportError and ModuleNotFoundError? This local name is then used to reference the accessed module throughout the code. Define a name in the local namespace within the scope of the import statement.Search the module by its name, load it, and initialize it.In Python, the import statement serves two main purposes: Understanding the “import” Statement import flask You can also check out this article to learn more about possible problems that may lead to an error when importing a library.You can check out our in-depth guide on installing flask here.If you’re using Ubuntu, you may want to try this command: sudo apt install flask.If you face this issue server-side, you may want to try the command pip install -user flask.In this case, to install flask for Python 3, you may want to try python3 -m pip install flask or even pip3 install flask instead of pip install flask You may have mixed up Python and pip versions on your machine.You can learn everything about relative imports and how to create your own module in this article. The ModuleNotFoundError may appear due to relative imports.Also verify that the folder contains the pip file.Īfter having followed the above steps, execute our script once again. Step 2: Once you have opened the Python folder, browse and open the Scripts folder and copy its location. Step 1: Open the folder where you installed Python by opening the command prompt and typing where python To fix the problem with the path in Windows follow the steps given next. Therefore, it is unable to install the library using pip in the correct path. Although pip may be installed on your system the script is unable to locate it. This likely happens because pip is installed but doesn’t reside in the path you can use. ![]() The error might persist even after you have installed the flask library. This is just to illustrate that you run it in your shell/terminal/command line. □ Note: Don’t copy and paste the $ symbol. If it isn’t, use the following two commands in your terminal, command line, or shell (there’s no harm in doing it anyways): $ python -m pip install -upgrade pip It assumes that your pip version is updated. This simple command installs flask in your virtual environment on Windows, Linux, and MacOS. To fix this error, you can run the following command in your Windows shell: $ pip install flask Make sure pip is installed on your machine. You need to install it first!īefore being able to import the Pandas module, you need to install it using Python’s package manager pip. ![]() The most likely reason is that Python doesn’t provide flask in its standard library. ModuleNotFoundError: No module named 'flask' Solution Idea 1: Install Library flask ![]() However, it only throws the following ImportError: No module named flask: > import flask This is supposed to import the Pandas library into your (virtual) environment. You’ve just learned about the awesome capabilities of the flask library and you want to try it out, so you start your code with the following statement: import flask Alternatively, you may have different Python versions on your computer, and flask is not installed for the particular version you’re using. The most frequent source of this error is that you haven’t installed flask explicitly with pip install flask. Quick Fix: Python raises the ImportError: No module named 'flask' when it cannot find the library flask.
