Spyder: Can't open Spyder even after fresh Anaconda install/in new environment
Description of your problem
What steps will reproduce the problem?
I've been having issues starting Spyder due to Qt Bindings. On a fresh anaconda install I've made a new environment, installed spyder and tried to open it with no luck i.e.
conda create --name spydertest
activate spydertest
conda install spyder
spyder
What is the expected output? What do you see instead?
I expected Spyder to launch however instead got the following error message:
Traceback (most recent call last):
File "D:\Anaconda3\envs\spydertest\lib\site-packages\qtpy\__init__.py", line 148, in <module>
from PySide import __version__ as PYSIDE_VERSION # analysis:ignore

During handling of the above exception, another exception occurred:

Did you run python bootstrap.py in your spyder directory first?

I hadn't ,that file wasn't in my directory, but when I downloaded it and ran it I received a similar error

qtpy.PythonQtError: No Qt bindings could be found
Ah right. Actually, that was my mistake; you should only need to do so when installing from source which you presumably weren't. The weird thing is that it says it is detecting PyQt, but then looks for PySide and can't find it? Could be cause I misinformed you about bootstrap.py, and it doesn't know what to do with a binary install...no clue. In any case, you have qt and qtpy in the environment, so not sure why its not finding them either way.
The commands you gave should produce the result, but can you create a new env with the Anaconda Navigator GUI (make sure to update it) and install Spyder via that method, to see if it works? I'm rapidly running out of ideas other than brute force methods, since this _should_ work...I just did it myself on Windows, twice.

Please report this in the Anaconda issue repo:
https://github.com/ContinuumIO/anaconda-issues/issues/
I really don't know why this is happening.

I have the same issue with Python 3.6.5, did you open a ticket at Anaconda's site ? (I did not find it immediately). I tried to update PySide as installed via conda but
$ conda install PySide
Solving environment: failed
UnsatisfiableError: The following specifications were found to be in conflict:
- pyside -> python=2.7
- python=3.6
Use "conda info <package>" to see the dependencies for each package.

@jfbu, you need to do
conda install pyqt
Thanks for the tip @ccordoba12 but
$ conda install pyqt
Solving environment: done
# All requested packages already installed.
Besides, uninstalling spyder and doing pip install -U spyder gives same situation
$ pip install -U spyder

Well I now did correctly pip install spyder after having activated the fresh virtual env (apologies, again) and exact same result as reported above.
jfbu
on 24 May 2018
Besides, uninstalling spyder and doing
pip install -U spydergives same situation
As our Readme, install guide, troubleshooting guide, wiki, and documentation all make clear, under no circumstances should you ever install Spyder via pip (or anything, if it is available on conda) especially if you are already running under Anaconda. It likely will not work, and can break your install.
ah sorry I had not activated the virtualenv how silly of me will correct.
You are running under conda and using virtualenvs? Well no, that will just not work at all. That's what conda-env is for.
So, your whole install might be broken after those two things so it might not even work now, but the correct way to install Spyder in a fresh conda env, as stated in those above resources, is to create a new py3.6 env with conda (conda create -n <newenvnamehere> python=3.6 and then just run conda install spyder. If that doesn't work, you may need to uninstall anything you did before with pip and virtualenv, and reinstall Anaconda.
If you're still having trouble, please try the steps listed in the Spyder Troubleshooting Guide, specifically the Basic First Aid and Emergency CPR sections, which resolve the great majority of Spyder installation issues.

Thanks for the quick reply.
You have guessed I read none of the above... I was looking for a quick fix.
If you would like a quick fix, I would suggest reading any of the above (the current versions on this repo or the spyder-docs one), as they present a very short and simple sequence of steps that will immediately allow you to install spyder and fix the problem (assuming your install isn't broken).
well sorry, but it is perfectly possible to set-up a python virtualenv with Python provided by conda. For a long time it did not work, but that was fixed some time ago.
It may be, but I'm not sure I understand why there is ever any reason to鈥攚hy even install conda, then? Since as the issue you linked states, even with the fix you can't really reliably use conda when using virtualenvs, you should only use pip, and thus you lose out on the benefits of the conda ecosystem in the first place.
Which brings us to our second point鈥攁s those documents all also mention, we lack the resources to provide individual post install help for user install problems from installing via pip as that method is for experts only, and can result in many tricky user-specific install problems that are difficult for us to help you with from here. Therefore, in such situations, we are only able to recommend you use conda instead, as it is particularly easy for you to do since you already have it installed鈥攁ssuming your installation isn't borked, the above two commands should get you up and running posthaste, if you're looking for a "quick fix" :)

Could clarify what makes you think this? That would be a very serious issue with Spyder/Anaconda if so. We only have received 3 reports of this error over the past 6 months since this one, and all of them were on Windows: one was someone downgrading their pip Qt install to a known unsupported version, one was clearly user install error (apparently in a similar fashion to this), and one had to do with a Windows and user-specific permissions issue with their Anaconda install.
Thanks for help. I will just wait until this get resolved eventually.
Sure, but not only should waiting not be necessary, but it is very unlikely to help, since your problem by all appearances (at least as you've described here) is not following the stated installed procedure, which none of us can fix from here.

Fwiw I have now, on another computer whose Anaconda install had seen none of my manoeuvers previously reported in my messages I did
$ conda create -n spyder python=3.6
and then
$ source activate spyder
$ conda install spyder
and the spyder on command line refuses to launch with the exact same error messages (edit: apart from line numbers) on command line as reported at top of this thread and then more recently by myself.
I am on Mac OS X 10.9.5.
jfbu
on 25 May 2018
Okay, thanks for clarifying. In that case, did you then try conda install pyqt? Some older versions of Spyder may not have had it installed automatically as a dependency since multiple versions were possible (I know that was true with pip, not 100% sure about conda). If the message is displayed as above, then that would probably be the possible anaconda bug discussed previously. In any case, you can try updating anaconda itself (conda update conda then conda update anaconda from the base environment, then create a fresh environment in the same way you did above, install spyder, and if it still doesn't work try pyqt5.6 instead (conda install pyqt=5.6) and see if it works under that.
CAM-Gerlach

Thanks for the quick help. I had updated my conda to 4.5.4. The install of spyder was accompanied as dependency by
pyqt: 5.9.2-py36h11d3b92_0
I then did a second attempt with first conda installing pyqt then spyder. But still no luck.
Then in that environment I followed your advice to install pyqt5.6 and now success.
$ conda install pyqt=5.6

I should add that I had been using spyder for perhaps three (four, actually) years (at various periods spaced by months of non-use) before these problems showed up: at some point a few weeks back I had wanted to use spyder again and I then hit these problems. This is why I recently wanted to give it a closer look and I tried to install it afresh.
jfbu
on 25 May 2018
Ah, excellent. Glad you got it working! I should have checked before (as I was thinking it might be, which is why I suggested it, but didn't think it would be dropped so soon), but the likely cause of your issue (unlike the OP) is that Qt 5.9 officially drops support for Mac OS 10.9. Obviously, nothing to do with Spyder, but something to be aware of. Thanks!
CAM-Gerlach
on 25 May 2018
Ok, thanks for the info about Qt 5.9 dropping me alone abandoned in the wild ;-). Thanks again for you very quick help!
jfbu
on 25 May 2018
Yeah, they were pretty quick on the trigger on that one, I guess to match the much faster upgrade pace of the Mac ecosystem vs. the Windows one (Windows 7, released in 2009, is still supported up through the current 5.11 version and probably for quite a while, while 10.9 was released in 2013, and the earliest macOS version supported in 5.11 is 10.11, released 2015). Of course, we have zero control over any of that... In any case, glad you got it fixed, and sorry for any confusion/miscommunication back there.
CAM-Gerlach
on 25 May 2018
@jfbu nasty problem points out (in my view) that we should perform a check of Qt > 5.9 and macOS < 10.11 to inform users that that combination is not allowed.
@CAM-Gerlach?
ccordoba12
on 26 May 2018
@ccordoba12 macOS < 10.10 for 5.9; its 5.11 that only supports 10.11 BTW
Sure, I guess鈥攊deally it should be handled at the conda or pyqt level by limiting 10.8 and 10.9 to PyQt 5.6 instead, but they ended up handling it by dropping support for pre-macOS 10.10 in Anaconda itself. Of course, we have no reason to be similarly restrictive, so if more users might run into this, best to include the check.
CAM-Gerlach
on 26 May 2018
I think it's better to add these warning in qtpy instead of in Spyder itself. I'll open a new issue for that.

pip uninstall PyQt5
and install qtpy
pip install qtpy
works for me

Glad you were able to get everything working.
QtPy is a Spyder dependency, so it should have been installed automatically when installing Spyder. Of course, for anyone else viewing this thread, we don't recommend using pip (vs. conda) unless you're willing and able to solve its problems on your own, which @TheodoreKrypton evidently was.
CAM-Gerlach

This error means that you installed pyqt5 with pip along side the pyqt conda package. It could be solved by you uninstalling the pip package.
Try:
pip uninstall PyQt5
Then update conda:
conda update conda
conda update anaconda-navigator
It will surely resolve your problem

Thanks for trying to help; however, this is known, closed issue who's actual cause (at least in the actual original issue report) is actually quite different from the one you state, and no further individuals have commented asking for assistance with it (or opened a new issue).
This error means that you installed pyqt5 with pip along side the pyqt conda package.
This could be one cause of that error, but apparently was not in this case based on the original issue report, and there are a number of potential others (including this one) which your suggestion does not address. Therefore, it will not surely resolve your problem.
conda update conda
Not explicitly necessary, but doesn't hurt.
conda update anaconda-navigator
The Anaconda Navigator GUI doesn't have anything to do with this; I'm not sure why you're suggesting it.
The above is also missing a crucial step for many if not most such cases, which is ensuring the conda PyQt package is installed properly: conda install --force-reinstall pyqt qt.
CAM-Gerlach
on 9 Mar 2019
@CAM-Gerlach Thank you very much, it worked for me!
To sum up, this is what I did to resolve the problem:
pip uninstall PyQt5
conda update conda
conda update anaconda-navigator
conda install --force-reinstall pyqt qt

I had this issue on a clean Anaconda install on Windows 7 as well. The cause of this issue (at least for me) was that my PATH variable contained another path with different Qt5 dll's before the anaconda path (Anaconda adds it to the user PATH, the other was in the system PATH, which takes precedence).
Solution: Either reorder your PATH (for example add anaconda to the start of the system PATH) or remove the other offending path(s). There is NO need to uninstall software as suggested in issue #8223...
So the issue is with PyQt5 not using its own dll's, I can image this could affect other platforms as well.

There is NO need to uninstall software as suggested in issue #8223
Actually there was, if another software doesn't modify PATH but install its own set of Qt5 libraries on C:\System\Win32 (or something similar). But that was fixed in one of the latest Anaconda releases.

I recked my conda environment after updating with --all for conda.
I tried with installing a fresh anaconda and update the conda and conda-build.
Created a new virtual env with python=3.6 and tried installing spyder in the environment after activating it.
I am getting below error:
