在 Windows 10 上为 PyPy3 安装 numpy 时出现问题 [英] Problem installing numpy for PyPy3 on Windows 10

问题描述

我在尝试在我的 Windows 10 机器上为 pypy3 安装 numpy 时遇到问题.

I am having issues trying to install numpy for pypy3 on my Windows 10 machine.

由于我无法判断此问题是源于我的 pypy3 安装还是其他原因，因此我在此处描述了到目前为止我已遵循的所有步骤:

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:

如官方所示 下载页面 我有:

• 下载并安装了Visual C++ Redistributable Package"vcredist.x86.exe
• 下载并安装了 Pypy3Windows 二进制(32 位)"文件 pypy3.6-v7.3.1-win32.zip

然后在手动将 pypy3 添加到我机器的 PATH 后，我有:

Then after having manually added pypy3 to the PATH of my machine, I have:

• 使用命令 pypy3 -m ensurepip
从 shell 安装了 pip 包

尝试安装numpy时出现问题.官方文档 说可以通过执行 pypy -m pip install numpy (在我的情况下为 pypy3 )来安装它，但这样做会引发以下错误:

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:

正如同一文档中所建议的，我也尝试使用实验性的 PyPy 二元轮使用命令:

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

但出现完全相同的错误消息.我应该注意到 this 相关线程中推荐的类似解决方法也失败了.

but the exact same error message appears. I should note that a similar workaround recommended in this related thread failed as well.

附加信息:

• 我安装了Visual Studio Build Tools 2019"(MSVC v142 - VS 2019 C++ x64/x86 Build Tools (v14.25))
• 我使用的是 pip 20.1 版和 setuptools 46.4.0 版
• 我已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)但无济于事(错误消息相同)

任何帮助将不胜感激.

推荐答案

感谢您在 Windows 上试用 PyPy 并报告问题.我们并没有真正的大型 Windows PyPy 社区，因此反馈很好.这里有两件事在起作用:

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:

• 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 版本之后修复了这个问题，但最好尝试弄清楚那里发生了什么，它是/曾经是 PyPy 中的一个错误.
• 构建失败，带有神秘的工具链损坏:无法链接简单的 C 程序".这与最新版本中从 MSVC9 (Visual Studio 2008) 到 MSVC14 (Visual Studio 2017, 2019) 的转换有关.它应该在 此提交中修复到 PyPy 中，这应该在下一个每晚构建

• 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
