pip install numpy以及运行Arch Linux的另一台机器上运行完美。
不幸的是，同一个命令无法在运行Gentoo的同事的机器上运行。
这是显示错误日志的pip.log： -

似乎我同事的机器上的gfortran与他试图在virtualenv中安装的numpy包不能很好地配合。知道为什么会这样吗？
答案 0 :(得分：7)
如果设置了CFLAGS，CXXFLAGS或LDFLAGS，则可能会导致此问题。问题是那些环境变量覆盖编译脚本中的设置，导致问题。
只是为了调用pip命令取消设置它们，你应该全部设置。

在我看来，setuptools无法正常工作，setuptools已被python“dist”实用程序取代，因此您可能需要安装它并重试安装。
