I'm getting an error while trying to execute jupyter-notebook in the console, the error happen here:
devnull = open(os.devnull, 'w')
FileNotFoundError: [Errno 2] No such file or directory: 'nul'
The strange thing is that it began to happen from one day to another, since until recently I could use jupyter-notebook perfectly, due to this error I uninstalled and then reinstalled anaconda, but the error persists.
My OS is Windows 10 and I installed the 64-bit installer with python 3.6
The Traceback is:

I tried to

Even tho i have the latest version of PIP
install resource
pip install resource
and it did not work
module 'time' has no attribute 'clock'
Are you using Python 3.8? This appears to be an issue with Python 3.8. I would suggest reverting to a older version of Python (3.7 works fine) until the libraries are resolved.

I used coda for a long time, with limited problems.
However, I recently installed Miniconda2 (Miniconda2-latest-Linux-x86_64.sh) on a HPC node.
Everything works fine, but I can not install multiple packages.
What happens, is that I install one package, and after that, I get the following error when I try to install a new one:

I am not sure what I am missing here. Would someone point me towards a potential solution not involving using sudo, as I have no rights?

I haven't made virtualenvs in a while, but the last time I did, there was no permissions issue. virtualenv is up-to-date. While I could go messing around with permissions in the specified file in the trace, I'd rather not. Has anyone else run into similar issues with virtualenv, and if so, how did you solve them?
EDIT
The error comes up when trying to make the virtualenv in ~/venvs (Ubuntu 12.04), the same place as before the problem starting occurring, so there's no mounting problem.
I'm fairly new to Python, and Nitrous.IO, and MongoDB, and command line in general so would appreciate a little guidance here if possible.
I'm trying to install pymongo on my Nitrous.IO box but can't seem to find a way to do it - this tutorial suggests 'import pymongo' but that didn't work (see below).
I can't seem to find any tutorials or help on this - a google search for "install +pymongo with nitrous.io" gave me 0 results.

Does anyone know how I would go about installing this? It's starting to be a real pain!
You might be able to install it withpip using this advice. Once you've done that, you would use the import pymongo at the top of your code file.
