问题
I am having issues trying to install numpy for pypy3 on my Windows 10 machine.
As I am unable to tell if this problem stems from my pypy3 installation or from something else I am describing here all the steps that I have followed so far:
As indicated on the official download page I have:
- downloaded and installed the "Visual C++ Redistributable Package"
vcredist.x86.exe - downloaded and installed the Pypy3 "Windows binary (32 bits)" file
pypy3.6-v7.3.1-win32.zip
Then after having manually added pypy3 to the PATH of my machine, I have:
- installed the
pippackage from the shell with the commandpypy3 -m ensurepip
The problem arises when trying to install numpy. The official documentation says that one can install it by doing pypy -m pip install numpy (pypy3 in my case) but doing so throws the following error:
Collecting numpy

As suggested in the same document I have also tried to use the experimental PyPy binary wheels with the command:
pypy3 -m pip install --extra-index-url https://antocuni.github.io/pypy-wheels/manylinux2010 numpy
but the exact same error message appears. I should note that a similar workaround recommended in this related thread failed as well.
Additional information:
- I have "Visual Studio Build Tools 2019" installed (MSVC v142 - VS 2019 C++ x64/x86 Build Tools (v14.25))
- I am using pip version 20.1 along with setuptools version 46.4.0
- I have made English the main language for my system (a possible non-ascii conflict was mentioned in the comments below)
- I have tried with other versions (pypy2.7 v7.3.1 and pypy3.6 v7.3.0) to no avail (same error message)
Any help would be greatly appreciated.
回答1:
Thanks for trying out PyPy on Windows and reporting problems. We don't really have a large Windows PyPy community, so feedback is good. There are two things at play here:
- The RPython error (think of it as a C level segfault in CPython), which might be caused by non-ascii path names. I think we fixed this after the 7.3.1 release, but it would be good to try to work out exactly what is going on there, it is/was a bug deep in PyPy.
- The failure to build, with the cryptic "Broken toolchain: cannot link a simple C program". This has to do with a transition from MSVC9 (Visual Studio 2008) to MSVC14 (Visual Studio 2017, 2019) in the latest release. It should be fixed in this commit to PyPy, which should land in the next nightly build
回答2:
Seems to be ppy3 is not properly installed. Try installing through wget.
wget https://bootstrap.pypa.io/get-pip.py
./pypy get-pip.py
Once installed, try installing numpy
pypy -m pip install numpy
