Windows (old versions): DLL load failed error #810

Do you have any idea what's the issue?

@giampaolo Looks like you built only half of the wheels for 4.1.0 compared to 4.0.0. It only gives you the vcvarsall.bat error when an appropriate wheel could not be found and it tries to download/build from source. vs See https://www.python.org/dev/peps/pep-0427/#file-name-convention The I've run into this issue in the past, it has to do with pip/wheel wanting to use @Mark-Booth Can you upgrade pip and/or wheel? python -m pip install -U pip
pip install --upgrade wheel |

I ran into the same problem with python3 and pip 7.1.2. Upgrade works: |
|
I remember I upgraded pip/wheel to their latest versions because we bumped into this issue already so it seems that somehow simply upgrading pip/wheel is not enough. Also I am not sure I understand the nature of the problem. Even worse, my Windows VM is gone so I have to reinstall Windows and the various Visual Studio suites (I feel sick just to think about that lol), and since I will fly to US next Monday I am afraid the issue will remain open for a while unless someone is able to produce the necessary exes/wheels, in which case he/she can send it to me and I will upload them on PYPI. |
|
Related note: Appveyor (https://ci.appveyor.com/project/giampaolo/psutil) would technically be able to produce exes/wheels, which would be good because it would mean avoiding to install different VS versions, which is a real pain, but I am not sure if and where they get stored. Let's say this is just a personal note to remember to investigate Appveyor in this regard. |
|
Going back off of distant memory when I ran into this issue, the version of pip/wheel on the build machine is what caused it to build wheels with different There's an issue in the packaged version of pip/wheel of the Windows Python distribution that only looks for an Also when you create virtualenvs, it would use an old bundled version of pip even if there was a newer one available. |
|
Ok thanks for the precious input (I don't use virtualenvs BTW).

I configured AppVeyor which now is able to produce and upload wheels/exes. I googled for |
|
@giampaolo these are coming from wheel (not from pip), but they're only warnings, and should not affect the actual wheel building. I'll need to apply the changes from pypa/pip#3383 to wheel (although I thought I already had) to suppress the warnings. |
|
Do the new 4.2.0 wheels (uploaded yesterday) have the same problem? I generated them on AppVeyor (not sure if that made any difference). |
|
I can't test your Windows wheels but they do all contain the cp* SOABI tags. That said, it looks like the build of Python 2.7 you're using is UCS-2, perhaps that is common on Windows, but most of the Linux world's builds are UCS-4. |
|
I tried installing via Windows and it attempted a source install. A quick fix would just be to rename the wheels to have |
|
Did pip show anything useful in the output before deciding to ignore the wheels and try the source? |
|
|
OK so I took a closer look at this by installing a fresh Win 10 box with no VS installed. I can reproduce the issue if I use pip 7.1.2 (as @mrjefftang) but after I upgraded pip ( |

On a second thought, if possible, perhaps it makes more sense to use the default pip version shipped with Python 2.7 and generate the wheels with that version of pip. |

Similar to issue #706 the current version of psutil doesn't appear to have windows installers.
