我在Windows 10计算机上尝试为pypy3安装numpy时遇到问题。
由于我无法确定此问题是我的pypy3安装还是其他原因导致的，因此我在这里描述了到目前为止我已经执行的所有步骤：
根据官方download page的指示，我有
vcredist.x86.exe pypy3.6-v7.3.1-win32.zip 然后将pypy3手动添加到我的机器的PATH后，我得到了：
pip从外壳程序安装pypy3 -m ensurepip软件包尝试安装numpy时出现问题。官方documentation表示，可以通过执行pypy -m pip install numpy（在我的情况下为pypy3）进行安装，但这样做会引发以下错误：

如同一文档中所建议，我还尝试通过以下命令使用实验性PyPy binary wheels：
pypy3 -m pip install --extra-index-url https://antocuni.github.io/pypy-wheels/manylinux2010 numpy
，但出现完全相同的错误消息。我应该注意，在this相关线程中推荐的类似解决方法也失败了。
其他信息：
任何帮助将不胜感激。

感谢您在Windows上试用PyPy并报告问题。我们实际上没有大型的Windows PyPy社区，因此反馈很好。这里有两件事在起作用：

似乎没有正确安装ppy3。尝试通过wget安装。
wget https://bootstrap.pypa.io/get-pip.py
./pypy get-pip.py
一旦安装，请尝试安装numpy
pypy -m pip install numpy
