pip install numpy退出生成时出错，但仍会安装

我想在我的virtualenv中使用fedora30和python 3.7.3在raspberry pi上安装numpy。我键入

pip install numpy

，过了一段时间，它会生成一条巨大的错误消息，其中一部分似乎与lapack/blas有关，但仍在安装某种numpy。我不确定在这种情况下我是否可以信任任何numpy结果，并希望得到关于消除构建错误的建议。当包含

sys/endian.h

时，生成报告一个致命错误

我安装了与我通常在装有fedora30的x64计算机上安装的相同的系统软件包，在那里我通常可以运行

pip install numpy

。在覆盆子上做这件事对我来说是新鲜事

我试图寻找一个提供

endian.h

的包：

dnf提供endian.h

，

dnf提供sys/endian.h

，但运气不佳

在my virtualenv中运行

pip install numpy

会在stderr上显示一条非常大的错误消息，并在stdout上显示以下文本：

我安装了通常在x64计算机上安装的相同系统包，但raspberry pi可能需要显式安装其他包

谢谢你的建议

pip卸载-y numpy

，然后

pip安装numpy--索引url=https://www.piwheels.org/simple/

Hi hoefling，键入第二条语句将返回以下文本：

查找索引：https://www.piwheels.org/simple/ 错误：找不到满足numpy要求的版本（来自版本：无）错误：找不到numpy的匹配发行版

pip中的

python-c有什么作用？\u internal.pep425tags import get\u supported；print（get\u supported（）[0]）“

output？@hoefling输出读取：

（'cp37'，'cp37m'，manylinux2014\u aarch64'）
