我在尝试在 Windows 10 计算机上安装 pypy3 的 numpy 时遇到问题。
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，所以我在这里描述了迄今为止我所遵循的所有步骤：
正如官方所示下载页面 I have:
- 下载并安装“Visual C++ Redistributable Package”
vcredist.x86.exe
- 下载并安装 Pypy3“Windows 二进制（32 位）”文件
pypy3.6-v7.3.1-win32.zip
然后手动将 pypy3 添加到PATH我的机器上，我有：
- 安装了
pip使用命令从 shell 打包pypy3 -m ensurepip
尝试安装 numpy 时出现问题。官方文档说可以通过以下方式安装它pypy -m pip install numpy (pypy3就我而言），但这样做会引发以下错误：

正如同一份文件中所建议的，我也尝试过使用实验性的PyPy 二进制轮子使用命令：
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。我应该注意到，推荐的类似解决方法this相关线程也失败了。
附加信息：
- 我安装了“Visual Studio Build Tools 2019”（MSVC v142 - VS 2019 C++ x64/x86 Build Tools (v14.25)）
- 我使用 pip 版本 20.1 和 setuptools 版本 46.4.0
- 我已将英语设置为系统的主要语言（下面的评论中提到了可能的非 ASCII 冲突）
- 我尝试过其他版本（pypy2.7 v7.3.1和pypy3.6 v7.3.0）无济于事（相同的错误消息）
任何帮助将不胜感激。
