Pip upgrading arcgis completely broke pip

Overview: While running Python 3.6, after upgrading my arcgis package, scripts no longer recognizes many packages and pip itself completely broke, making it impossible to upgrade or uninstall any packages.
Background Info: Fairly recently, when I run a particular program of mine, I have been seeing a deprecation message connected to the arcgis package. So, I upgraded the arcgis package to see if it fixed it. It seemed to install correctly but then when trying to run my program, I'd get errors for other packages, like folium or requests. I then tried upgrading Python and initially, it worked. I used pip to install pandas and requests but right after I installed arcgis, everything broke again. So then when trying to uninstall arcgis (or do anything else pip related) I get this error:
FileExistsError: [WinError 183] Cannot create a file when that file already exists: 'C:\Users\myuserpath\AppData\Local\.certifi'
I've uninstalled Python but it doesn't change anything. pip install any package results in this error. I tried reverting back to Python 3.6 but the installer wasn't available from the python site, only 3.9.
What could have been changed or affected by this arcgis installation?

There seems to be two primary issues you're dealing with. The first is as #BoarGules mentioned, that arcgis does a 'full' install with all its dependencies and that could be causing problems. Secondly, the newest requests library seems to have some issues as well, at least from what I've experienced. So let's get started fixing all this.
There's probably a few different ways to fix this, so this is just one of the many. First, uninstall python and delete the python folder from your AppData folder - in your case, it would be the Python 3.9 folder. Re-install Python and check your site-packages folder making sure it only contains the default Python packages. Open up a command prompt and do a pip install of something basic, like pandas. If that goes well, then the first hurdle is over.
When it comes time to install arcgis again, you'll want to use this instead
pip install arcgis --no-deps
this will prevent the doubling up of any of the packages or whatever seems to be happening. You will need to then also install these:
pip install ujson
pip install requests_ntlm
Next, when you come to installing requests, use an older library, like this one:
pip install requests==2.20.0
That should get things back up and running.

Windows machine Installing pycurl module on Thonny

I am trying to install pycurl module in Thonny virtual environment but without any luck..
Whatever I try, I am getting the same error message:
Please specify --curl-dir=/path/to/built/libcurl
I have previously installed this module on my Raspberry PI linux and did not have any issues whatsoever. Seems like a lot of people are having issues installing it on Windows Machine and there is still no clear solution to this.
According to the official pycurl website:
http://pycurl.io/docs/latest/install.html#windows
I should be able to install pycurl by using pip install pycurl. That is not the case unfortunately.
Also, they provide a link that is not working:
Clicking on the link returns "Forbidden".
Hoping to get some clarification. Thanks in advance.

If you want to install the current version, you need to build it from source.
You may be able to find a binary of a previous version to install through pypi.

How to install gensim without pip (firewall issues)

All-
I would like to use the gensim library, but unfortunately I can't install it via pip due to the company's firewall. Any advice? Thank you in advance for any help or suggestions you can provide.

Tedious and only solution then is to download all the dependencies one by one and install them along with gensim. So, go to pypi and download gensim first and install it, then it might raise errors saying some package is missing or trying to download it.Then, download that specific package and install it via pip by giving path to the downloaded whl or source file

ImportError in bluemix

i am making a python app in IBM bluemix,but when i pushed it,it had an error:
i found my python version is 2.7.10 ,so i thought maybe the reason is the too low,and i change the version to 3.5.1 in runtime.txt like this:
python-3.5.1
but it still didn't work and had the same error.I know I should install this package, but how can i install this in bluemix?
Can anyone please give me a solution?

Looking at your error, it says you are missing the lxml library. This is not installed as part of the standard Python package, so you will need to install it with either pip or conda, depending on what you have setup.
pip install lxml

Yeah,I solved it. in bluemix, if you use some package that not as part of standard python package, you should write them in your requirements.txt, and then bluemix will download this package.

When you do the cf push, if there is a requirements.txt file on your root folder, it will install all the dependencies on Bluemix.

Setuptools error when trying to install a package

I’m completely new to Python and I want to install the package py-webrtcvad in Windows 7, but I'm stuck at the error ImportError: No module named 'pip.utils.setuptools_build'. There is an answer to this problem in stackoverflow which seems to solve the problem for others, but it doesn't work for me.
Here’s a summary of what I’ve done and tried so far:
Installed Python 3.5 and set up the Windows path environment so
that it works from any directory.
Installed pip for Python.
Tried to install the package with python -m pip install webrtcvad,
but it failed, returning the error Unable to find vcvarsall.bat.
I found a blog that deals with the vcvarsall.bat
problem: blogs.msdn.microsoft.com/pythonengineering/2016/04/11/unable-to-find-vcvarsall-bat. Following the directions of that blog:
First I just installed Visual C++ Build Tools 2015 and tried installing the package straight away (without updating setuptools), but I received a lot of error messages (which I didn’t write down).
I tried reinstalling setuptools, which I did following the directions in https://pypi.python.org/pypi/setuptools: I removed the version of setuptools that came with my Python installation (v20), and installed the latest version (v30). This time I got a different error message when trying to install py-webrtcvad: ImportError: No module named 'pip.utils.setuptools_build'.
Asked for assistance in the Python official chat. They made three
suggestions:
Updating pip with python -m pip install --upgrade pip. Didn’t
work. Again, the error ImportError: No module named 'pip.utils.setuptools_build'.
Reinstalling Visual C++ Build Tools 2015. No difference, same error
again.
Reinstalling Python itself. The Python installer offers three
choices: Repair, modify and uninstall.
Repair: Didn’t work. Same error.
Modify: Doesn’t look like it offers useful modifications for this.
Uninstall: Uninstalled and reinstalled. Still the same error.
I’m out of ideas. Can you help me?
Note: I imagine this should be doable in Windows 7 with Python 3.5. However, if it isn't I'm open to trying anything different. For example, installing a different version of Python would be no problem at all. I could also try installing Linux if that will solve the problem.

There was a bug in version 2.0.8 of webrtcvad that caused it to use the wrong flags when compiling for Windows: it was using -DWEBRTC_POSIX instead of -DWIN32. This might have been the source of the "lot of error messages" you got during one of your early attempts.
The fixed version has been pushed to pypi as version 2.0.9. I've confirmed that pip install webrtcvad works correctly on Windows 10. I'm using a pretty fresh install of Python, so I would try it first without reinstalling setuptools.
