问题
I am trying to install numpy from whl file. I get the error:
numpy-1.9.1%2Bmkl-cp34-none-win_amd64.whl is not a supported wheel on this platform.
Details: Windows 8.1 pro x64, elevated command prompt
Python 3.4.2
package numpy from Gohlke\'s site
numpy-1.9.1%2Bmkl-cp34-none-win_amd64.whl copied in the pip.exe folder
The log file shows:
d:\\Program Files\\WinPython-64bit-3.4.2.4\\python-3.4.2.amd64\\Scripts\\pip run on 01/23/15 11:55:21 numpy-1.9.1%2Bmkl-cp34-none-win_amd64.whl is not a supported wheel on this platform. Exception information: Traceback (most recent call last): File \"D:\\Python34\\lib\\site-packages\\pip\\basecommand.py\", line 122, in main status = self.run(options, args) File \"D:\\Python34\\lib\\site-packages\\pip\\commands\\install.py\", line 257, in run InstallRequirement.from_line(name, None)) File \"D:\\Python34\\lib\\site-packages\\pip\\req.py\", line 167, in from_line raise UnsupportedWheel(\"%s is not a supported wheel on this platform.\" % wheel.filename) pip.exceptions.UnsupportedWheel: numpy-1.9.1%2Bmkl-cp34-none-win_amd64.whl is not a supported wheel on this platform.
What is wrong?
回答1:
Short answer: rename the file to numpy-1.9.1%2Bmkl-cp34-none-win32.whl to install it.
You can check what tags your pip tool accepts for installation by running:
import pip; print(pip.pep425tags.get_supported())
In this case pip is incorrectly detecting your operating system to be 32-bits and the file you're trying to install was win_amd64 in its filename.
If you rename the file to numpy-1.9.1%2Bmkl-cp34-none-win32.whl (which now contains the tags that are considered supported) then you can install the package. It's a trick because the file is still built for 64-bits but this allows you to install the package as intended.

After several tests I think the problem is "win32" or "amd64" itself. I tried replacing those two with "any" and it worked.
I'm pretty much a newbie on these kind of installation/compilation thing, so excuse me if I misled anyone, just thought that if it worked for me, it might work for someone else.

In my case workaround to install gohlke packages on python (3.4.4 (AMD64)) was to change the "cp34m" part rather than "win*" parts above:
python -c "import pip; print(pip.pep425tags.get_supported())":
[('cp34', 'none', 'win_amd64'), ('py3', 'none', 'win_amd64'),
('cp34', 'none', 'any'), ...
ls -ld *:
matplotlib-2.0.0b3-cp34-cp34m-win_amd64.whl
numpy-1.11.1+mkl-cp34-cp34m-win_amd64.whl
pandas-0.18.1-cp34-cp34m-win_amd64.whl
Change above names to:
matplotlib-2.0.0b3-cp34-none-win_amd64.whl
numpy-1.11.1+mkl-cp34-none-win_amd64.whl
pandas-0.18.1-cp34-none-win_amd64.whl
eg, pip install matplotlib-2.0.0b3-cp34-none-win_amd64.whl
Processing ...
...Successfully installed matplotlib-2.0.0b3

To add to the list of other possible solutions, I had to upgrade pip itself. The latest binary from Gholke's site had the "cp27m" tag, which didn't show up when I checked the pip tags using:
import pip; print(pip.pep425tags.get_supported())
After I upgraded pip, the wheel didn't work but just doing a regular pip install numpy worked

The current Winpython Package Manager need a 2-characters fix to accept to recognize the new numpy+mkl 'wheel'. https://github.com/stonebig/winpython/commit/5e13230609a2e9f4d66d98c3776207ce4b4dd050
回答6:
As a workaround, uninstall numpy package: pip uninstall numpy then install it again from cache: pip install numpy I had the same problem with several packages after upgrade from 3.4.1 to 3.4.2.
回答7:
Navigate to the directory where your 'pip.py' sits and then type following on win command '..\python.exe pip.py install name_of_package.whl'.
This should work.

I had the same problem tried to work out with the suggested solutions. I changed win64 to win32 and it didn't work as well. But then I changed the name to original and this time it worked! The only extra thing I did was to go offline.that's so strange.
回答9:
If you have, say, Python 3.4 installed, make sure to install the -cp34- version of the wheel and not -cp35-.
回答10:
This has nothing to do with your operating system. Uninstall Python 32bit and install Python 64bit rather or alternatively find a 32bit wheel file.
