在 Windows 上为 PyPy3 安装 numpy 时出现问题 10
Problem installing numpy for PyPy3 on Windows 10
我在尝试在我的 Windows 10 机器上为 pypy3 安装 numpy 时遇到问题。
因为我无法判断这个问题是源于我的 pypy3 安装还是源于我在这里描述的到目前为止我所遵循的所有步骤的其他原因：
如官方所说download page 我有：
- 下载并安装了 "Visual C++ Redistributable Package"
vcredist.x86.exe
- 下载并安装了 Pypy3 "Windows binary (32 bits)" 文件
pypy3.6-v7.3.1-win32.zip
然后在将 pypy3 手动添加到我机器的 PATH 之后，我有：
- 使用命令
pypy3 -m ensurepip 从 shell 安装了 pip 包
尝试安装numpy时出现问题。官方 documentation 说可以通过 pypy -m pip install numpy （在我的例子中是 pypy3 ）安装它，但是这样做会引发以下错误：

正如同一文档中所建议的，我还尝试将实验性 PyPy binary wheels 与命令一起使用：
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 相关线程中推荐的类似解决方法也失败了。
附加信息：
- 我已经 "Visual Studio Build Tools 2019" 安装了 (MSVC v142 - VS 2019 C++ x64/x86 构建工具 (v14.25))
- 我使用的是 pip 20.1 版和 setuptools 46.4.0 版
- 我已经将英语作为我系统的主要语言（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（同样的错误信息）
如有任何帮助，我们将不胜感激。
似乎是ppy3没有正确安装。尝试通过 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
感谢您在 Windows 上试用 PyPy 并报告问题。我们实际上并没有很大的 Windows PyPy 社区，所以反馈很好。这里有两件事在起作用：
- RPython 错误（将其视为 CPython 中的 C 级段错误），这可能是由非 ascii 路径名引起的。我 认为 我们在 7.3.1 版本后修复了这个问题，但最好尝试弄清楚到底发生了什么，它 is/was PyPy 中的一个深层错误.
- 构建失败，含糊不清"Broken toolchain: cannot link a simple C program"。这与最新版本中从 MSVC9 (Visual Studio 2008) 到 MSVC14 (Visual Studio 2017、2019) 的过渡有关。它应该在 this commit 中固定到 PyPy，它应该在下一个每晚构建
我在尝试在我的 Windows 10 机器上为 pypy3 安装 numpy 时遇到问题。
因为我无法判断这个问题是源于我的 pypy3 安装还是源于我在这里描述的到目前为止我所遵循的所有步骤的其他原因：
如官方所说download page 我有：
- 下载并安装了 "Visual C++ Redistributable Package"
vcredist.x86.exe - 下载并安装了 Pypy3 "Windows binary (32 bits)" 文件
pypy3.6-v7.3.1-win32.zip
然后在将 pypy3 手动添加到我机器的 PATH 之后，我有：
- 使用命令
pypy3 -m ensurepip 从 shell 安装了
pip 包
尝试安装numpy时出现问题。官方 documentation 说可以通过 pypy -m pip install numpy （在我的例子中是 pypy3 ）安装它，但是这样做会引发以下错误：

正如同一文档中所建议的，我还尝试将实验性 PyPy binary wheels 与命令一起使用：
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
附加信息：
- 我已经 "Visual Studio Build Tools 2019" 安装了 (MSVC v142 - VS 2019 C++ x64/x86 构建工具 (v14.25))
- 我使用的是 pip 20.1 版和 setuptools 46.4.0 版
- 我已经将英语作为我系统的主要语言（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（同样的错误信息）
如有任何帮助，我们将不胜感激。
似乎是ppy3没有正确安装。尝试通过 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
感谢您在 Windows 上试用 PyPy 并报告问题。我们实际上并没有很大的 Windows PyPy 社区，所以反馈很好。这里有两件事在起作用：
- RPython 错误（将其视为 CPython 中的 C 级段错误），这可能是由非 ascii 路径名引起的。我 认为 我们在 7.3.1 版本后修复了这个问题，但最好尝试弄清楚到底发生了什么，它 is/was PyPy 中的一个深层错误.
- 构建失败，含糊不清"Broken toolchain: cannot link a simple C program"。这与最新版本中从 MSVC9 (Visual Studio 2008) 到 MSVC14 (Visual Studio 2017、2019) 的过渡有关。它应该在 this commit 中固定到 PyPy，它应该在下一个每晚构建
