问题
I want to use Pypy to run a set of data transformations faster, but I need numpy installed so that the script runs unchanged (obviously I could change the script but that's not the point). I tried using pip as the docs told me to, but it just won't work. It gives me an error about not having Visual Studio 14.1, which I do have theoretically (I installed as many redistributables as you can think of, including the 2017 version, which is the same 14.1 as far as I can tell).
I'm also aware of the possibility of downloading the module and executing the setup or cloning it from github, but getting pip to work would be nice as I'm interested in downloading quite a few of them in the near future.
Still, I'm very noobish when it comes to Windows, so I'll be glad if you have any idea of why it isn't working.
This is the error and log I get from Windows Shell:
PS C:\WINDOWS\system32>pypy3 -m ensurepip
PS C:\WINDOWS\system32>pypy3 -m pip install numpy

Upgrade: I managed to install sympy using pip without any problems. I could also install numpy using the method described by mattip. Still, most packages keep giving me the Microsoft Visual error or a similar one.
回答1:
pip can install either a binary compiled package or can download and compile the source code of the package. But it cannot compile from source without a compiler. Either
- install the compiler and learn to build c-extension modules from source (not recommended)
or
- always use
pip install --only-binary :all: <package>to force pip to fail if there is no binary
You can find binary wheels for windows at https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy, you need the ones that have a pp372 in the name (pp for PyPY, 3 for python 3, 72 for pypy 7.2.x)
