Failing to pip install cesium

[pkgandhi]

Hello,

I am not able to install the cesium package through pip install even though all the dependencies are satisfied. I am getting something like following. Does anyone know what is going on here:

Thanks!

[stefanv]

Thanks for the bug report, @pkgandhi. Which commands did you run to generate the above?

If you haven't yet, please also try:

pip install --upgrade pip
pip install .

[pkgandhi]

@stefanv : Pip says it is up to date! Doing "pip install ." it says File setup.py not found. It is kind of bizarre, ain't it?

[stefanv]

Did you run pip install . in the Cesium source directory?

[pkgandhi]

Somehow I am not able to locate Cesium source directory. It is trying to collect from cache, but I am unable to locate it. Any ideas how to find it?

[pkgandhi]

@stefanv I tried downloading source and doing pip install . - still did not work. Getting the following error:

Hi @pkgandhi, we don't officially support Windows so I'm not surprised that this isn't working. However, I'm willing to try and sort it out if you can provide us a little more information; there shouldn't be anything in the library that can't be made to work with a proper Windows development environment.

Can you try copy-pasting the entire output here (it would be better to provide the whole text in a ``` block instead of a screenshot)? The line you're giving us basically just says that an error occurred, but we need the rest of the traceback in order to see what in particular went wrong.

Hi @bnaul, sure! Attached is the screenshot:

Attached are the screenshots. Let me know if these would help!

Thanks!

Great, thanks for the expanded output. That error appears because you don't have a C compiler installed: our package has some features which are implemented in C and integrated into our Python code via cython. Here is a link that describes how to install a C compiler for Windows: https://github.com/cython/cython/wiki/CythonExtensionsOnWindows. I believe once you have a C compiler the package should compile and load correctly, but again, we haven't explicitly tested this on Windows.

I'm going to close this for now since this isn't a bug in cesium per se, but feel free to keep commenting here. I personally would strongly recommend that you set up a Linux-like environment for your development, e.g. using Docker: https://docs.docker.com/engine/installation/windows/. But that's just my personal preference :).

Hey! Sorry to bring back this issue from the dead, coming back to this to say that I was unable to install cesium using pip on Windows 10. I have Anaconda and made a separate Python 3.6 environment for this, installed all the dependencies succesfully. I installed the Visual Studio Build Tools 2017 so I have a compiler available.

Unfortunately, the compilation fails, here is what pip gives me.

So the first error is this:

error: Command "C:\Program Files (x86)\Microsoft Visual 
Studio\2017\BuildTools\VC\Tools\MSVC\14.14.26428\bin\HostX86\x64\cl.exe /c /nologo /Ox /W3 /GL /DNDEBUG /MD -IC:\Users\me\AppData\Local\conda\conda\envs\tensorflow\lib\site-packages\numpy\core\include -IC:\Users\me\AppData\Local\conda\conda\envs\tensorflow\lib\site-packages\numpy\core\include -IC:\Users\me\AppData\Local\conda\conda\envs\tensorflow\include -IC:\Users\me\AppData\Local\conda\conda\envs\tensorflow\include -I"C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Tools\MSVC\14.14.26428\include" -I"C:\Program Files (x86)\Windows Kits\10\include\10.0.17134.0\ucrt" -I"C:\Program Files (x86)\Windows Kits\10\include\10.0.17134.0\shared" -I"C:\Program Files (x86)\Windows Kits\10\include\10.0.17134.0\um" -I"C:\Program Files (x86)\Windows Kits\10\include\10.0.17134.0\winrt" -I"C:\Program Files (x86)\Windows Kits\10\include\10.0.17134.0\cppwinrt" /Tccesium\features\_lomb_scargle.c /Fobuild\temp.win-amd64-3.6\Release\cesium\features\_lomb_scargle.obj" failed with exit status 2

Then this:

Installing from source gave pretty much the same result.

I have no clue which other compiler to use for this, they seem to all not support Python > 3.4. Any help would be greatly appreciated! Thanks

Hi there, same here on windows 8.1 with the same compiler.

I'm usually able to build packages either from windows comand window or from a git bash.

Both give the exact same compiler error

Thanks for your help, Olivier

Hi @beeb and @goldentom42, MinGW works for Python 3.6. Please try that and let us know if that solves your installation issues.

[prathamsolanki]

I'm also encountering the same issue as @beeb on Windows 10. I too have a similar Python 3.6 Anaconda environment. @beeb have you tried @acrellin 's solution with MinGW? Has it worked? so I may do the same as well.

[beeb]

Please see this how-to. I'm trying it right now EDIT: It works!

[prathamsolanki]

Yeah worked for me as well!
