How to use pip to install dtrx?

[Ehsan Hajiramezanali]

Hi,

I want to use pip to install dtrx. However, I got the following error.

~~~
$ pip install --allow-external dtrx dtrx
DEPRECATION: --allow-external has been deprecated and will be removed
in the future. Due to changes in the repository protocol, it no longer
has any effect.
Collecting dtrx
  Could not find a version that satisfies the requirement dtrx (from versions: )
No matching distribution found for dtrx
~~~

Is there any way to solve this problem?

Thanks in advance.

Best regards,
Ehsan
