I see this question is a little old, but I'll put my experience here in case it helps others googling. The easiest solution for me was to install the Anaconda distribution: https://store.continuum.io/Note there is a "very free" version for general use, and a nice academic version for ... well, academic use. :)
我看到这个问题有点老了，但我会把我的经验放在这里，以防它帮助其他人使用谷歌搜索。对我来说，最简单的解决方案是安装 Anaconda 发行版：https: //store.continuum.io/请注意，有一个“非常免费”的通用版本，还有一个不错的学术版本……嗯，学术用途。:)
Numba is actually supported by the Continuum folks, at least according to one of their tutorials. I've installed it and am just now starting to play around with the thing. I've liked it thus far (although have had some minor trouble getting it to play nice with some Cython modules I previously created). If you go the Continuum route, they have a somewhat hidden blogI've found useful (the link on the main page is under "Company", which is not the first place I look). Check out their things tagged "Numba;" there are examples there.
Numba 实际上得到了 Continuum 人员的支持，至少根据他们的一个教程。我已经安装了它，现在才开始玩这个东西。到目前为止，我一直喜欢它（尽管在让它与我之前创建的一些 Cython 模块配合使用时遇到了一些小问题）。如果你走 Continuum 路线，他们有一个有点隐藏的博客，我发现它很有用（主页上的链接在“公司”下，这不是我第一次看到的地方）。查看他们标记为“Numba”的东西；那里有例子。
My other secret reason for using Numba via Anaconda: since they seem to be relatively new, I speculate they may be very "on top of" addressing Qs or problems getting Numba working for you in their distrib -- wanting to build a good name and product and all that. This is, of course, just pure speculation on my part.
我通过 Anaconda 使用 Numba 的另一个秘密原因：因为它们似乎相对较新，我推测它们可能非常“在”解决 Qs 或让 Numba 在他们的发行版中为您工作的问题——想要建立一个好名字和产品等等。当然，这只是我的纯粹猜测。
The only downside: no inclusion of Picloud in Anaconda. I have used that quite a bit in the past, so this is disappointing. It just means a little more work for myself, but zero work is nice :)
唯一的缺点：Anaconda 中没有包含 Picloud。我过去经常使用它，所以这令人失望。这只是对我自己意味着更多的工作，但零工作很好:)
Note: I'm not affiliated with Continuum at all. I'm just pleasantly surprised with their product thus far.
注意：我根本不隶属于 Continuum。到目前为止，我对他们的产品感到惊喜。

I hope you are on Linux and you have pip installed. On my Debian Linux, I can easily install numba by following commands:
我希望你使用的是 Linux 并且你已经安装了 pip。在我的 Debian Linux 上，我可以通过以下命令轻松安装 numba：
sudo apt-get install build-essential
sudo apt-get install llvm
pip install llvmpy
pip install cython
pip install numba
Then you are done!
然后你就完成了！

I had same problem and I fixed it just by importing pandas before importing quantecon in my code:
我遇到了同样的问题，我只是通过在我的代码中导入 quantecon 之前导入 pandas 来修复它：
import pandas as pd
import quantecon as qe
It works for me.
这个对我有用。
