Hello, i'm am new at coding in python, I want to make simple code to convert images to pdf, but I have been trying for 3 hours to install img2pdf, I tried everything, my OS is windows 10 and I'm using Python 3.9, when I try to use pip install img2pdf there are some problems with the "wheel", I discovered Pillow has not yet launched for 3.9 and I was wondering if this is the same case or something else.

I'm sorry, I cannot help you unless you show me exactly what your problem is. In this case I need the precise error messages you are getting. You also cannot go to a car mechanic and ask them to repair your car without them having a look at what's actually broken.

Failed to build pikepdf Pillow lxml
ERROR: Could not build wheels for pikepdf which use PEP 517 and cannot be installed directly

I guess the problem is, that you are a too early user of Python 3.9. :)

The problems you are having have nothing to do with img2pdf. What's happening is, that Pillow, pikepdf as well as lxml are not offering binaries for Python 3.9 yet. So pip tries to compile everything which fails because you are missing dependencies.

I think your best option is to use Python 3.8 and wait until all projects update their binary releases for 3.9.

*By Sebastián on 2020-10-13T02:12:10.271Z* Hello, i'm am new at coding in python, I want to make simple code to convert images to pdf, but I have been trying for 3 hours to install img2pdf, I tried everything, my OS is windows 10 and I'm using Python 3.9, when I try to use pip install img2pdf there are some problems with the "wheel", I discovered Pillow has not yet launched for 3.9 and I was wondering if this is the same case or something else. --- *By josch on 2020-10-13T07:06:00.897Z* --- I'm sorry, I cannot help you unless you show me exactly what your problem is. In this case I need the precise error messages you are getting. You also cannot go to a car mechanic and ask them to repair your car without them having a look at what's actually broken. --- *By Sebastián on 2020-10-13T11:54:25.866Z* --- Hello, sorry, this is the error im getting: C:\Users\anima>pip install img2pdf Processing c:\users\anima\appdata\local\pip\cache\wheels\90\f5\7f\b88a76bac33669118e7549f4856bbe975a3ad2e59280c59196\img2pdf-0.4.0-cp39-none-any.whl Collecting pikepdf Using cached pikepdf-1.19.3.tar.gz (2.4 MB) Installing build dependencies ... done Getting requirements to build wheel ... done Preparing wheel metadata ... done Collecting Pillow Using cached Pillow-7.2.0.tar.gz (39.1 MB) Collecting lxml>=4.0 Using cached lxml-4.5.2.tar.gz (4.5 MB) Building wheels for collected packages: pikepdf, Pillow, lxml Building wheel for pikepdf (PEP 517) ... error ERROR: Command errored out with exit status 1: command: 'c:\users\anima\appdata\local\programs\python\python39\python.exe' 'c:\users\anima\appdata\local\programs\python\python39\lib\site-packages\pip\_vendor\pep517\_in_process.py' build_wheel 'C:\Users\anima\AppData\Local\Temp\tmp_44fpmhq' cwd: C:\Users\anima\AppData\Local\Temp\pip-install-oo15k3_v\pikepdf Complete output (23 lines): running bdist_wheel running build running build_py creating build creating build\lib.win-amd64-3.9 creating build\lib.win-amd64-3.9\pikepdf copying src\pikepdf\codec.py -> build\lib.win-amd64-3.9\pikepdf copying src\pikepdf\jbig2.py -> build\lib.win-amd64-3.9\pikepdf copying src\pikepdf\objects.py -> build\lib.win-amd64-3.9\pikepdf copying src\pikepdf\_cpphelpers.py -> build\lib.win-amd64-3.9\pikepdf copying src\pikepdf\_methods.py -> build\lib.win-amd64-3.9\pikepdf copying src\pikepdf\_version.py -> build\lib.win-amd64-3.9\pikepdf copying src\pikepdf\__init__.py -> build\lib.win-amd64-3.9\pikepdf creating build\lib.win-amd64-3.9\pikepdf\models copying src\pikepdf\models\encryption.py -> build\lib.win-amd64-3.9\pikepdf\models copying src\pikepdf\models\image.py -> build\lib.win-amd64-3.9\pikepdf\models copying src\pikepdf\models\matrix.py -> build\lib.win-amd64-3.9\pikepdf\models copying src\pikepdf\models\metadata.py -> build\lib.win-amd64-3.9\pikepdf\models copying src\pikepdf\models\outlines.py -> build\lib.win-amd64-3.9\pikepdf\models copying src\pikepdf\models\__init__.py -> build\lib.win-amd64-3.9\pikepdf\models running build_ext building 'pikepdf._qpdf' extension error: Microsoft Visual C++ 14.0 or greater is required.
