Installation fails due to conflicting colorama version

[NeolithEra]

Hi, users are unable to run Xontrib-readable-traceback due to dependency conflict with colorama package. As shown in the following full dependency graph of Xontrib-readable-traceback, Xontrib-readable-traceback requires colorama>=0.3.7，while backtrace>=1.0.2 requires colorama==0.3.7.

According to pip’s “first found wins” installation strategy, colorama 0.4.3 is the actually installed version. However, colorama 0.4.3 does not satisfy colorama==0.3.7.

Dependency tree-----------

xontrib-readable-traceback - 0.3.2
| +- backtrace(install version:0.2.1 version range:*)
| | +- colorama(install version:0.3.7 version range:==0.3.7)
| +- colorama(install version:0.4.3 version range:>=0.3.7)

Thanks for your help.
Best,
Neolith

Solution

1. Loosen the version range of colorama to be <=0.3.7.
2. Remove your direct dependency colorama, and use the colorama transitively introduced by backtrace.
3. Ask your direct dependency backtrace to loosen the version range of colorama to be >=0.3.7.
   @vaaaaanquish Which solution do you prefer, 1 ,2 or 3?
   Please let me know your choice. May I pull a request to solve this issue?

@NeolithEra Thanks.
I prefer 2 or 3. The reason is simple, we don't want to lower the version.
I think the safest and fast way is 2.

May I pull a request to solve this issue?

Of course you're welcome.

I hit this as well today, making this xontrib not work.
