I'm on a new computer, and have to install Django again, so I typed the pip install Django command in my VSCode terminal to install it. However, after it downloads, I get this message:
WARNING: The script django-admin.exe is installed in 'C:\Users\Xiaow\AppData\Roaming\Python\Python39\Scripts' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
Because of this, I can't start any new projects. How would I install this script to PATH? Is there a command I have to do or something?
There also seems to be a .vscode folder in 'C:\Users\Xiaow' but I don't know if this is what is making Django not install the admin script to PATH.
Everything else works, like I can go to my existing projects (copied over from my old computer) and runserver, and can access all the databases. However, it's just this admin script that is causing problems. I also tried uninstalling and reinstalling Django to no avail.

I'm pretty sure that you need to add the path from the script to your list of environment variables... You can do so by running a command.
Try running this in the windows command prompt:
set PATH=%PATH%;C:\Users\Xiaow\AppData\Roaming\Python\Python39\Scripts
Also, here is the source of the command listed above:
Adding a directory to the PATH environment variable in Windows
UPDATE:
Just learned that the set command only sets the variable for the current session, so if you want the change to stay permanent then go ahead and use setx instead.

I am trying to set up my environment for ATOM for python. I did this on my previous PC and didn't run into much trouble but this time I believe something is messed up and I don't know how to fix it.
Linter-flake8 installation:
I installed it by doing this:
settings --> install --> search packages --> linter-flake8 --> install.
Dependencies were installed afterward automatically.
then I ran the CMD and installed flake8 using:
py -m pip install flake8
When I try typing my code into ATOM; I get this error:
[Linter] Error running Flake8 Error: Failed to spawn command `flake8`. Make sure `flake8` is installed and on your PATH
at C:\Users\yazan\.atom…\lib\helpers.js:130
(anonymous) # C:\Users\yazan\.atom…ter\dist\index.js:1
Things I tried to fix this:
Adding ATOM to my path, which I did but did not work (ATOM and
Python both are in my user and system, environment variables)
Checking that my ATOM is running the same version of python.
import sys
print(sys.version)

Thanks!
As mentioned in the linter-flake8 README, you can set the executablePath in the package settings. This should help you get around Atom's flaky support for environment variables.
I wanted to install Django in my virtual environment (which was completely working), but got this whole lot of errors. Anyone know what to do?
I just typed this in PowerShell:
pipenv install django
And got this:

It looks like your original download may have failed, and pip is using the cached download instead of getting a new one. Try pipenv lock --clear and then pipenv install django again.

I had the same error. Changed my system python by doing the following in VS Code:
Under the view menu select 'show command pallet'. One of the commands you can then select from the command palette is 'Python: Select Interpreter'.
Selecting this option will allow you to choose which version of python to use.
This post is pretty old but I found a different solution that might help others out. For me, the issue was my IDE/Python (venv). I am using Visual Studio ver. 1.57.1 as of now on Windows 10.
Open Visual Code.
Go to 'View' on the toolbar.
Click on 'Command Palette...' (or press CTRL + SHIFT + P on Windows).
Search for: 'Python Select Interpreter'.
Click on: 'Enter interpreter path...' followed by 'Find...'.
Go to your (venv) scripts folder: project_folder/venv/Scripts.
Select python.exe or pythonw.exe inside of your project_folder/venv/Scripts folder.
That's all.
The Flask-SQLAlchemy was installed in my virtual environment (venv). But my VSCode was using the system/PC Python interpreter to find the packages instead of the venv.
Hope this helps someone else out.
I had the same issue, this worked for me:
In cmd, cd to your project folder, (for me i had to activate venv, so it showed (env) C:\ etc\etc>)
Then install it here with:
pip3 install flask-SQLAlchemy
for some reason this took this noob 12 tries, but the give away was there was no sqla files in my site folder, and it kept showing the install had taken place in my python39 folder.
This is for people who do not use Anaconda (I had this issue and I solved it this way)
Your venv might be incorrect. Did you copy paste your venv from another directory?
venv saves path information, so when you run env\Scripts\activate, the venv believes it is in a different directory.
It will install the packages in the OLD directory. Make sure you generate a new py -m venv env for every app you create rather than copy pasting.
The solution is to delete your current venv directory, and run the py -m venv env command again. Then the packages will be installed in the current venv.
Had the same issue, resolved using:
activate the venv
use pip3 to install flask and flask_sqlalchemy by running:
pip3 install flask_sqlalchemy flask
And lastly checking if correct python interpreter was selected in vscode from:
CMD + Shift + P --> Python: Select Interpreter --> selecting appropriate python version for the venv (preferably python10)
I had the same problem, but it worked when I changed to Python Interpreter under the command palette of the view tab. If you believe you have installed all required packages and it does not work then definitely try this.
One thing I have noticed is that if I change the python interpreter from command palette(ctrl+shift+p) to my virtual environment one it does not work. First I tried the command,
py -3 -m pip install flask-SQLALchemy
Instead of the above command, I upgrade pip by using,
python -m pip install --upgrade pip
then I tried using the following to import SQLAlchemy.
python -m pip install flask-SQLALchemy
and it worked for me.
When you have done changes, I mean change your python interpreter, delete your env or re-create install packages again. Please close your app.py file and re-open it. Some times it still gives your error.
For anyone looking for a more recent answer. I couldn't find a scripts folder. On my ubuntu machine I did this (in vscode):
ctrl + shft + p
search select python interpreter
enter interpreter path
navigate to your-app/venv/python3
select python3
This resolved the import issue.
I am pretty new in Power BI and I try to set up the python script in it.
I have changed the option and activated the Python scripting. After that I get the error:
DataSource.Error: ADO.NET: Python script error.

As you see I am using anaconda3 but there is another Python is installed on my macheine. I tried a lot of ways and nothing could help
Open the Anaconda Prompt:
Then, you have to go to the Conda Environment that you want to use in PowerBI. Am having an environment 'temp', so I activate it first in the 'Anaconda Prompt':
(base) C:\Users\ashish>conda activate temp
Then I go to the directory having the "PowerBI" executable file in the installation folder:
(temp) C:\Users\ashish>cd "C:\Program Files\Microsoft Power BI Desktop\bin"
Then, I launch PowerBI from the Prompt:
(temp) C:\Program Files\Microsoft Power BI Desktop\bin>PBIDesktop.exe
This fixes the NumPy error you are getting. If you want any other package to use with PowerBI, install that package in the respective "Conda Environment" (in my case it is "temp").
forget Anaconda and use WinPython.
I tried Anaconda for days with all the workarounds available in StackOverflow and other forums, and they took me nowhere.
Then I tried WinPython, and it worked immediately. Of course, you will need to change the PowerBI options accordingly.
To install WinPython: https://github.com/winpython/winpython
To change the detected Python home directory: https://learn.microsoft.com/en-us/power-bi/connect-data/desktop-python-scripts#enable-python-scripting
If you consider my answer above others, you won't need to downgrade Python, PBI, or anything else.
I had similar issue trying to get Power BI to use Anaconda Python. After seeing a post about PBI having issues with Python 3.7 I:
Created a new environment in Anaconda using the Anaconda Navigator and made sure the new environment were using Python 3.6 (so NOT 3.7).
Installed in that environment the packages such as Pandas, Matplotlib and Seaborn that were used in my Power BI Python script
Went to Power BI's settings: File/Options and Settings/Options/Python scripting and set "Other" for Detected Python home dir and instead navigated to my new 3.6 python environment directory (visable in Anaconda Navigator at the bottom of the screen when selecting that environment)
..and that worked fine.
I think this error can be due to some numpy issues with Anaconda distribution.
I changed the Python path in Power BI to a virtual environment (which uses pip instead of conda to install numpy and other packages) and I had no more issues.
Here is my problem: To work, I need to to set up an environment by sourcing some script. This script is setting up a virtual environment that I was not aware of.
Until I needed to use django module that I did not have. So I used pip to install the module. It did not work, i got an error message ImportError: No module named django so I investigated why. I found out, that i am using a virtualenv.
Here is my sys.path:
['',
'/home/user/myenv/release/lib/Linux_x86_64/debug',
'/home/user/myenv/tools',

'/home/user/myenv/tools/python/lib/python2.7/lib-tk',
'/home/user/myenv/tools/virtualenv/lib/python2.7/site-packages']
If I try to install django again, I get a message from pip
$ pip install django
Requirement already satisfied (use --upgrade to upgrade): django in /home/usr/myenv/tools/virtualenv/lib/python2.7/site-packages
Cleaning up...
My question is why and how do I fix this to use django?
UPDATE
I have tried running source /home/user/myenv/tools/virtualenv/bin/activate
and then install django with pip. No difference.
