pip install plyvel not working on Windows platform #60

josephernest · 2017-11-11T02:07:23Z

Are there no binaries for Python 2.7 - Windows?
Currently

pip install plyvel

produces installation error on Python 2.7 - Windows if you don't have the right compiler installed.

Thanks in advance.

wbolster · 2017-11-11T23:08:17Z

there are no binaries (wheels) at all on pypi. and i have not used windows in 15 years so i'm afraid i cannot help you with that.

josephernest · 2017-11-11T23:19:48Z

Thank you for your answer @wbolster. Is plyvel the "official" LevelDB for Python 2.7, or is there another implementation ready-to-use for Linux, Mac, Windows? (including binaries)

wbolster · 2017-11-16T16:39:56Z

not that i am aware of. plyvel is (or at least was) the fastest and most feature complete leveldb library for python.

would be an idea for you to provide a windows build in the form of a .whl package? i can publish it on pypi.

wbolster · 2018-01-05T21:40:19Z

plyvel 1.0.1 is on pypi, with binary linux packages! please give it a try!

wbolster · 2018-01-06T21:58:22Z

if you have experience with making builds for windows using https://www.appveyor.com/ i would be more than happy to bless these as official and submit them to pypi. (update: actually no:#60 (comment))

however, i have neither time, skill, nor interest to accomplish this myself.

metatsmith · 2018-01-13T23:38:11Z

I believe the problem here is that the C Standard Library headers have become platform dependent. I'm also running into this same problem, and I've looked around the web a bit after a lot of frustration (which I imagine @josephernest is also feeling. The potential solution I am testing right now is to install the windows SDK kit for my system. I have windows 7, so I'm using the windows 7 SDK.

This article leads me to believe this should work:
https://social.msdn.microsoft.com/Forums/vstudio/en-US/cfa48739-cd32-43d2-9d27-2b6653da6645/canf-find-standard-c-header-file-in-visual-studio-2015-community-version?forum=vclanguage

Windows7 SDK : https://www.microsoft.com/en-us/download/details.aspx?id=3138
Windows10 SDK: https://developer.microsoft.com/en-us/windows/downloads/windows-10-sdk

I'll post a follow up after I do some experimentation.

wbolster · 2018-02-07T12:30:23Z

see also #70, perhaps it helps

wbolster · 2018-02-27T15:37:40Z

@bauerj #60 (comment)

i see you are working on this?
bauerj@5acbdea

bauerj · 2018-02-27T15:45:11Z

Yes, well, I'm trying: https://ci.appveyor.com/project/bauerj/plyvel/build/job/rpfrwrjvoj26ffjf

The current issue is that Microsoft does not supply stdint.h with their SDK (although it seems to be part of the C standard).

This could be solved by adding the header file to this project. What do you think about doing that?

Or maybe the library can be changed to not use that file. As far as I can see it only uses uint64_t from there. I'm a C noob but maybe unsigned long long could be used instead?

vaskomitanov · 2018-03-01T05:24:48Z

Few months ago I needed windows build of the latest LevelDB and I worked a little bit to have usable windows build. Here is the link in case you may find it useful for above problems: https://github.com/vaskomitanov/leveldb

ofek · 2018-12-09T20:42:58Z

Any progress on this? Many of us Windows users would greatly appreciate binary wheels 🙏

wbolster · 2018-12-09T22:35:52Z

i am not working on this myself. if anyone gets automatic builds working on appveyor on (a fork of) this repo, i would be happy to merge it

Few months ago I needed windows build of the latest LevelDB and I worked a little bit to have usable windows build. Here is the link in case you may find it useful for above problems: https://github.com/vaskomitanov/leveldb

tx. i created a lib with vs2017, then modified the setup.py,like that

Extension(
		...
		libraries=['leveldb vaskomitanov-r x64',
				   'libboost_chrono-vc141-mt-x64-1_69',
				   'libboost_date_time-vc141-mt-x64-1_69',
				   'libboost_filesystem-vc141-mt-x64-1_69',

				   'libboost_thread-vc141-mt-x64-1_69'],
		...
    )

finally my plyvel was installed.

@Myriad-Dreamin
Could you give some more details about creating the lib? which set.py did you modify? I'm new to vs, and I'm suffering from the same plyvel installation problem. Thank you a lot!

UPD: solved! for people who may need help: compile boost.lib and LevelDB.lib using VS, you'll see how to reach this step following a tutorial for it.

xyqyear · 2019-04-13T13:48:46Z

It seems like the latest release of leveldb (1.21) added native support for Windows. Would you consider to figure this out and add this support also for plyvel? I also don't know how to compile a program on windows, so I cannot offer help. (I'm from China, so sorry for my poor English)
Thanks very much!

Many people will find it helpful to install with PIP, I think.

i see. i not has pypi account, you can try to build you self if you want to build in windows 1. install Visual Studio 2017 2. install https://github.com/Microsoft/vcpkg 3.vcpkg install leveldb "vcpkg install leveldb:x64-windows" 4.install cython, "pip3 install cython" 5.build cpp file,"cython --cplus --fast-fail --annotate plyvel/_plyvel.pyx" 6.build pxd and include leveldb, "python setup.py build_ext --include-dirs=%VCPKG_PATH%/%VCPKG_SYS_PATH%/include --library-dirs=%VCPKG_PATH%/%VCPKG_SYS_PATH%/lib --libraries=shlwapi" 7.install package or build wheel，"python setup.py install" or "python setup.py bdist_wheel" 8. finish namuyang <notifications@github.com> 于2019年4月22日周一下午2:09写道

you must include leveldb library.
try to install vcpkg to build leveldb or use wheel package.

For anyone who wants to install on windows, I've build a windows x64 version using github action which build against the main branch of leveldb.

If this windows built works it would be huge! I will check out soon

Well @synodriver I did install and run it on python 3.10 and it works in terms of importing and basic stuff; but I still end up with the same error as explained here: #137

so @wbolster to get back to your comment #137 (comment)
I'm guessing this is a issue with your repo, since now that I could directly install your repos windows build provided by @synodriver and still ended up with the same issue ...

You need another library, snappy.

It doesn't matter what browser you use pretty much all of them have leveldb storages in similar paths

I hava no idea whether snappy is linked against leveldb during the compilation. It just able to compile.

Your windows build is useless if it's not linked to snappy, because it most likely breaks every time there's a leveldb that uses compression (such as the leveldb that browsers create)

Has anyone managed to get plyvel working on Windows with Snappy support? If so, how? I feel like I've tried every version of pre-compiled wheel available in the various threads relating to this issue here on Github, always with the same result;

plyvel._plyvel.CorruptionError: b'Corruption: corrupted compressed block contents'

I'm currently using plyvel_wheels-1.3.0-cp310-cp310-win_amd64.whl and it works fine to a point, however as soon as any other app applies any kind of compression to the db, I start getting the above error in plyvel.

Nope and repo maintainer don't give a fuck about windows, so this is pretty much a helpless case plyvel will never be compatible with windows

You should link leveldb with snappy.

You should link leveldb with snappy.

@lifegpc If you are using google chrome and are on windows, you can just open Run (by pressing Windows + R) and paste %LOCALAPPDATA%\Google\Chrome\User Data\Default\Local Storage\leveldb to find a not plyvel decompressable leveldb database. I also had written a entire issue ticket explaining this issue a while ago #137

set "INCLUDE=%INCLUDE%;Path to snappy directory"
set "LIB=%LIB%;Path to the snappy library"

You should set these variables before build leveldb.

Are the pre-compiled wheels packaged with plyvel-wheels not linked with snappy? I'd assumed they had to be otherwise what's the point of providing them?

synodriver · 2023-12-10T09:06:40Z

Update: I successfully linked plyvel with leveldb and snappy (using conda install -c conda-forge leveldb)

but when I test it with Edge's data with db = plyvel.DB(r"C:\Users\LAB\AppData\Local\Microsoft\Edge\User Data\Default\Local Storage\leveldb"), just got a segfault (Process finished with exit code -1073741819 (0xC0000005)). So something must be wrong with leveldb or snappy on windows, I think.

synodriver · 2023-12-10T09:13:15Z

Envs:

(py310) C:\Windows\system32>conda  list|findstr leveldb
leveldb                   1.23                 h699a171_1    conda-forge
(py310) C:\Windows\system32>conda  list|findstr snappy
snappy                    1.1.10               hfb803bf_0    conda-forge
(py310) C:\Windows\system32>python -V
Python 3.10.12

My fork at https://github.com/synodriver/plyvel, maybe someone else can have a try with conda environment to see what's wrong, at least it can link with snappy.
