我的python版本是2.7.10.
My python version is 2.7.10.
我进行了一些研究，并尝试了以下解决方案，
I made some research and tried the following solutions,
brew install halo
这不起作用，我的终端返回了:
This did not work and my terminal returned:
Error: No formulae found in taps.
我在自制软件中检查了我的公式，但是找不到Halo.但是，我找到了其他软件包，因此我的Homebrew可以正常工作.
I checked my Formulae in Homebrew and could not find Halo. However, I found other packages so my Homebrew work otherwise.
我尝试通过更改别名并再次安装halo来将python版本更改为3，但它也不起作用.
I tried chaning my python version to 3 by changing alias and installing halo again, and it did not work either.
alias python='python3'
错误提示与python2相同，如上所述.
Error massage was the same as for python2, as above.
我需要为学校实验室提供光环，并且需要使用Mac.

推荐答案
这似乎是该软件包的已知错误:
It looks like it's a known bug for that package:
https://github.com/manrajgrover/halo/issues/79
您只需要通过以下方法更新设置工具:pip install -U setuptools
You just have to update setup tools via: pip install -U setuptools
如果这不起作用，请尝试添加--user标志:pip install --user -U setuptools
If that doesn't work, try adding the --user flag: pip install --user -U setuptools
这篇关于安装软件包halo会显示错误:"install_requires"必须是包含有效项目/版本要求说明符的字符串或字符串列表的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
