Question

我正在尝试使用嵌入式Python运行一些C ++代码。两周前，Code完全正常运行。代码仍在编译，但我现在收到错误

Traceback (most recent call last):

从那时起，我所做的唯一改变就是安装macOS Supplemental Update并将Python从2.7.13_1升级到2.7.14_2（使用Homebrew）。我更改了makefile中的相关链接器标志，即我键入python-config --ldflags时出现的标志。我还确保我使用的Python绝对是Homebrew，它是按照Homebrew的指示将export PATH="/usr/local/opt/python/libexec/bin:$PATH"插入我的.bash_profile。

我不确定这个错误是因为Python更新，最近的macOS补充更新还是其他原因。知道问题可能是什么？

我有同样的问题; 在python 2.7中，NumPy 1.8.0可用，然后我使用brew安装NumPy（再次），我的python（2.7）中不再可用。（你得到了同样的错误）

所以我做了＃34; brew unlink python＆amp;＆amp; brew link python＆＃34;使用NumPy 1.14可用的python 3（而不是2）。我猜python 2.7与最新版本的NumPy不兼容。

Python嵌入，ImportError：无法导入名称_remove_dead_weakref
