I'm having troubles running the lightnovelapi, a Python library for accessing text from lightnovel websites, on any {file_name}.py
executable file.
I have tried:
Running pip3 install lightnovelapi.
Running python -m pip install lightnovel.
Running which python and which pip and using all versions of python and pip listed in the combinations of Steps 1 & 2 above.
Switching from originally using Windows 10 to MAC OS.
Downloading condas and creating conda envs and running steps 1-3.
Any advice on how to successfully install,import and run this library?

I am trying to install mmcv python package, but Ubuntu terminal crashes every time during installaction (application simply closes without any errors). I tried to install this package both using standard Linux terminal and via VS Code - the result is always the same. It causes no errors when I install other python packages, but when I try to install mmcv - terminal crushes.
I am using this code for installation:
pip install mmcv-full==1.3.9 -f https://download.openmmlab.com/mmcv/dist/cu117/torch1.13.1/index.html
I tried to install mmcv using this code in Kaggle Kernel (it is Jupyter Notebook-like development environment, which works on Linux too) - and package was installed correctly.
It seems to me that my terminal crashes because mmcv is quite "heavy" python package, but I do not know what to do with it. How can I solve this problem and install mmcv?
It seems like my version of Ubuntu is not compatible with old versions of mmcv.
This code worked for me:
pip install -U openmim
mim install mmcv-full==1.5.0 -i https://pypi.tuna.tsinghua.edu.cn/simple
I am using Mac M1 now, when I am trying to import lxml in my python code, it shows below:
I've tried
my Python version is : Python 3.9.12
my lxml version is: 4.9.1
The main reason Spyder can't find 'lxml' is I used standalone Spyder, in order to fix this, I have to use a separate environment.
1 - Follow below article to create a new virtual environment
https://packaging.python.org/en/latest/guides/installing-using-pip-and-virtual-environments/#creating-a-virtual-environment
2 - Follow below article to install necessary packages in the new environment, which link to Spyder IDE later, all issues will be fixed.
https://github.com/spyder-ide/spyder/wiki/Working-with-packages-and-environments-in-Spyder#installing-packages-into-the-same-environment-as-spyder
Your development environment may be using a different Python installation. Run python -c "import lxml" in the same shell where you ran pip install .... If that works, then configure your development environment (there is an FAQ link on your screenshot).
It may also happen that pip and python belong to different Python installations. To fix it, use python -m pip install ... instead of pip install ....
For example, if you run python -m pip install lxml, that should install lxml, then running python -c "import lxml; print('OK')" should display OK.
I am running Python 3.8.3. Previously I had Python 3.6 installed.
When I try to install by pip e.g.
pip install requests
I get the error
Fatal error in launcher: Unable to create process using '"c:\users\myname\appdata\local\programs\python\python36\python.exe" "C:\Users\MyName\AppData\Local\Programs\Python\Python36\Scripts\pip.exe" install requests'
Uninstalling Python 3.6 did not resolve this. I also tried reinstalling pip from https://pypi.org/project/pip/#files.
How can I get pip working again so I can install packages again?
On a side note, the reason I installed 3.8.3 in the first place instead of continuing with 3.6 was that Windows opened its app store any time the python command was used in PowerShell. I figured I might as well download the new version, since at the time I saw no reason to fight it. Still, it would be nice to know how to stop Windows from commandeering this.
If typing python in your command prompt opens python 3.6 then try py -3 or another possible PATH variable you have set for python 3.8
then to use pip for just that python version do the following command
[PATH VARIABLE] -m pip install [py-package]
e.g.
python -m pip install requests
When you are runing pip install requests, it runs the first pip it finds on th path. You can see from the error message, that it is using c:\users\myname\appdata\local\programs\python\python36\python.exe, so you are not really installing anything for Python 3.8.
If running python on your computer runs Python 3.8, then I suggest using this option to run pip:
python -m pip install requests
And if you have to enter full path to start python3.8, than do that:
/full/path/to/python.exe -m pip install requests
I can't install any python modules that require python 2.7 or later. I have uninstalled everything that Mac would let me that was related to python 2, and I run everything on python 3. I am completely lost. I am on Mac and whenever I try to install a module(like praw) this pops up.
I used the command
pip install praw

ERROR: Package 'praw' requires a different Python: 2.7.16 not in '>=3.5' ```
Welcome to Stack Overflow Malachi! I believe you're looking for the command pip3 (pip3 install praw) to install Python 3 packages through pip. If you open your terminal and type man pip to get the manual page, there is a line that says:
pip is the command to use when installing packages for Python 2, while pip3 is the command to use when installing packages for Python 3.
Looks like the most recent version of praw requires Python 3.5 or greater.
The last version that supported Python 2.7 was praw 5.4.0. If you're still using Python 2.7 and need this package, try running
pip install praw==5.4.0
If you're using Python 3.x, check to see if you're using the right version of pip. If you have both Python 2 and Python 3 installed on your system, you'll likely need to install system wide packages using pip3 instead if pip. In this case, try running
pip3 install praw
Alternatively, if you're targeting a specific Python interpreter (e.g. python3.7, python3.8, etc), and want to be certain that you are using the correct pip executable for your interpreter, you can run pip as a Python package via
python3 -m pip <args>
where python3 can be replaced by any interpreter path.
When I run python -V from terminal, I see that Python 2.7.10 is installed. I want to keep this as the "global" version as OSX utilizes it.
When I run Idle, I see that Python 3.6.0 is running. How do I install libraries to this version of Python?
For example, if I run pip install bs4, the library is installed here beautifulsoup4 in /Library/Python/2.7/site-packages/beautifulsoup4-4.5.3-py2.7.egg - which is obviously Python 2.7.
So when I run my script from Idle, I get the following error:
ModuleNotFoundError: No module named 'bs4'
You want to use virtualenv. It sounds like you have two versions of Python installed and you need to focus on one while being able to manage the packages in each. Virtualenv will do this for you.
First install virtualenv (https://virtualenv.pypa.io/en/stable/),
Second run it specifying the version of python you want as so: `virtualenv -p /usr/bin/python2.6
Third you can use pip to install packages directly into this environment. This increases the amount of disk space you need, but will allow you greater control over your code.
When you have two versions of python, you will need to specify which version of python you would like to run. You can do this with the activate command. For example:
activate python3
Once you have activated the python 3 environment, you can then run pip:
pip3 install bs4
which will install the beautiful soup library in your python 3 environment.

pipVERSIONNUMBER install will install the library to the correct version of Python.
$ pip2.6 install otherpackage
$ pip2.7 install mybarpackage
