Installing Pylint for Windows
Details here. What could be causing this error? The log file state " SyntaxError: invalid syntax" the code is:. The syntax error is probably a separate problem; I see that your site is up and running right now, so perhaps you worked out what it was and fixed it? Thanks for your support and suggestions!
My site is indeed up and running but the error message persists in the in-browser editor while I didn't fix anything else. I tried Moissessantiago's suggestion but this results in error multiple messages about undefined names. Toggle navigation. Try to use: from flask import Flask Regards.
Does this work? After taking a closer look there are two more things to point out: 1 It looks like there is a space between "log" and " ". Thanks Leapfrog, excellent catches! Happy to pay it forward.

No config file found, using default configuration pylint 1. Thanks, I think we don't understand any of Sqlalchemy's library. This might require some updates in astroid's brain tips to support sqlalchemy by providing hints on how the library looks.
I guess you are right ibakirov. Same problem. Python 3. For folks commenting here about switching to flake8, there are multiple solutions to this problem without waiting for a solution from pylint itself:. Coming here and commenting that switching to flake8 is a solution to your problem means that you were never interested in the first place to fix it using what pylint offers you already.
And as I mentioned earlier, we don't support sqlalchemy out of the box. It doesn't. YoungWilliamZ Is there a solution for newest flask? Turbid Same for me, loading the plugin does clear all the errors in the vscode. However, it also stops detecting other errors. For example: it stops showing error for db. Columnasdasda as well. I just append random string at the end Is there still no official solution to this issue?
I don't want to have to use YoungWilliamZ solution. Load the installed plugin. For example, if you use VS code, please edit setting. Unfortunately, when I installed pylint-flask and added the entry in setting. Is there anyway to have your pylint plugin recognize sqlalchemy's relationship declaration? Code like that is showing errors for pylint: [no-member] Instance of 'relationship' has no 'name' member [E].
PyLint “Unable to import” error – how to set PYTHONPATH?
Hi btoconnor sorry for the delay Skip to content. Dismiss Join GitHub today GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.I have a sub-directory package in my project and inside the package I import a module from the top level, ie.
Inside two. However, when I run PyLint on two. On second thought, this probably won't fix your specific problem. I misunderstood the question and thought that two. And considering the differences in the way Python 2.
Still, if you do eventually switch to Python 3 and plan on using a module as both a package module and as a standalone script inside the package, it may be a good idea to keep something like.
EDIT: And now for a possible solution to your actual problem. Either run PyLint from the directory containing your one module via the command line, perhapsor put the following code somewhere when running PyLint:.
I had the same problem and since i could not find a answer I hope this can help anyone with a similar problem. I use flymake with epylint. Basically what i did was add a dired-mode-hook that check if the dired directory is a python package directory. In my case I consider a directory to be a python package if it contains a file named "setup. In fact, I tried setting the init-hook first but this did not resolve the issue consistently across my code base not sure why.
Once I added it to the system path probably a good idea in general my issues went away. In case anybody is looking for a way to run pylint as an external tool in PyCharm and have it work with their virtual environments why I came to this questionhere's how I solved it:. Now using pylint as an external tool will run pylint on whatever directory you have selected using a common config file and use whatever interpreter is configured for your project which presumably is your virtualenv interpreter.
I'm creating a new project using flaskbut when I create a new file and import Flask I receive this error: No name 'Flask' in module 'flask'pylint no-name-in-module. I installed flask on python 2. Then I updated python to python 3. I simply uninstalled flask and installed again and it worked for me. Run this two commands:. I solved this changing my python interpreter. I did uninstall pylint and install pylama and now all is fine! Learn more. Pylint error: no name in module when import a package Ask Question.

Featured on Meta.Update: only my debugger in VScode is giving me this error, but when I run the script it gets past this before it fails.
Can you activate the specific environment you set up? Also, try this-- from the command line, activate the virtual environment and run Python. Did it succeed? Well, I actually just fixed the issue.
I had to clean up a lot of my straggling interpreters that I had installed through pyenv. It was making it very difficult to know and understand which interpreter that I had sourced because VS tried to source it for me I guess. Is there a preferred IDE for dealing with virtual envs? I like to set up my virtual environments with the older virtualenv on the command line, and then in the IDE, I point the project's interpreter at the Python installed in the virtualenv's bin folder.
It is good to have the command line skills, you appreciate it most when you are actually deploying on a remote server and all you have is a command line prompt! But a great IDE that handles virtual environments very well is Pycharm. About all you need is their GUI to manage environments. That being said, VSCode is pretty excellent once it is set up properly. Because it is smaller and simpler it quite a bit faster than PyCharm and more suited to low-resource machines.
I have used Pycharm in the past and actively elect to use virtualenv. Posting to the forum is only allowed for members with active accounts. Please sign in or sign up to post. I forgot my password. Aaron West Points.

Flask is a lightweight Python framework for web applications that provides the basics for URL routing and page rendering. Flask is called a "micro" framework because it doesn't directly provide features like form validation, database abstraction, authentication, and so on. Such features are instead provided by special Python packages called Flask extensions.
The extensions integrate seamlessly with Flask so that they appear as if they were part of Flask itself. For example, Flask doesn't provide a page template engine, but installing Flask includes the Jinja templating engine by default.
For convenience, we typically speak of these defaults as part of Flask. In this Flask tutorial, you create a simple Flask app with three pages that use a common base template. Along the way, you experience a number of features of Visual Studio Code including using the terminal, the editor, the debugger, code snippets, and more. The completed code project for this Flask tutorial can be found on GitHub: python-sample-vscode-flask-tutorial.
If you have any problems, feel free to file an issue for this tutorial in the VS Code documentation repository. To successfully complete this Flask tutorial, you must do the following which are the same steps as in the general Python tutorial :. Install the Python extension. You can check the location by running path at the command prompt.
If the Python interpreter's folder isn't included, open Windows Settings, search for "environment", select Edit environment variables for your accountthen edit the Path variable to include that folder. In this section, you create a virtual environment in which Flask is installed. Using a virtual environment avoids installing Flask into a global Python environment and gives you exact control over the libraries used in an application.
A virtual environment also makes it easy to Create a requirements. In that folder, use the following command as appropriate to your computer to create a virtual environment named env based on your current interpreter:. Note : Use a stock Python installation when running the above commands. If you use python.
Open the project folder in VS Code by running code. Then select the Python: Select Interpreter command:. The command presents a list of available interpreters that VS Code can locate automatically your list will vary; if you don't see the desired interpreter, see Configuring Python environments. From the list, select the virtual environment in your project folder that starts with. Note : On Windows, if your default terminal type is PowerShell, you may see an error that it cannot run activate.
The error provides a link for information on how to allow scripts. The selected environment appears on the left side of the VS Code status bar, and notice the " venv " indicator that tells you that you're using a virtual environment:.
Install Flask in the virtual environment by running one of the following commands in the VS Code Terminal:. You now have a self-contained environment ready for writing Flask code. You know the environment is activated when the command prompt shows env at the beginning.Posted by: admin November 20, Leave a comment.
I have a sub-directory package in my project and inside the package I import a module from the top level, ie. Inside two. However, when I run PyLint on two. The solution to alter path in init-hook is good, but I dislike the fact that I had to add absolute path there, as result I can not share this pylintrc file among the developers of the project. This solution using relative path to pylintrc file works better for me:.
Note that pylint. One workaround that I only just discovered is to actually just run PyLint for the entire package, rather than a single file.
Somehow, it manages to find imported module then. In fact, I tried setting the init-hook first but this did not resolve the issue consistently across my code base not sure why.
