我在Windows 10机器上安装numpy for pypy3时遇到了问题。
由于我无法判断这个问题是源于我的pypy3安装还是其他原因，我在这里描述一下我目前所遵循的所有步骤。
按照官方的说明 下载页面 我已经。
vcredist.x86.exe pypy3.6-v7.3.1-win32.zip然后在手动将pypy3添加到了 PATH 的机器，我已经。
pip 命令从shell中取出软件包 pypy3 -m ensurepip问题出现在试图安装numpy的时候。官方的 文件 说可以通过以下方式安装 pypy -m pip install numpy (pypy3 在我的例子中），但这样做会出现以下错误。

正如同一文档中所建议的，我还尝试使用实验性的 PyPy二进制轮子 命令，但出现了完全相同的错误信息。
pypy3 -m pip install --extra-index-url https://antocuni.github.io/pypy-wheels/manylinux2010 numpy
但出现了完全相同的错误信息。我需要注意的是，在下面的文章中也推荐了类似的解决方法。这个 相关线路也失败了。
其他信息。
任何帮助将是非常感激的。
谢谢你在Windows上试用PyPy并报告问题。我们并没有一个大型的Windows PyPy社区，所以反馈很好。这里有两个问题。
似乎是ppy3没有正确安装。试试通过wget安装。
wget https://bootstrap.pypa.io/get-pip.py
./pypy get-pip.py
安装后，尝试安装numpy
pypy -m pip install numpy
