Try to make the Scala working on my Atom

Scala is a relatively complicated programming language.  We need to use the sbt to make it run. 

I tried to make it work on Atom, to make an IDE for Scala on Atom.

I first go to Atom=>File=>Settings=>Install , search "Ensime", and install it. 

And I ctrl+shift+p , to find ensime: Start. and I got an error " no ensime file found".

So I tried to generate ensime file using sbt etc. 

I went to 

http://ensime.org/build_tools/sbt/

http://www.scala-sbt.org/

And download sbt. 

And I follow the following post, the last one, 

"add a plugins folder and plugins.sbt in %username%.sbt\0.13\"

https://www.reddit.com/r/scala/comments/58ysn9/how_to_use_sbt_ensimeconfigure_in_ensime_plugin/

And on the windows cmd prompt, I went to the sbt directory 

And I use the command "sbt" to go to sbt mode. And under sbt mode, I run ensimeConfig. Something wrong. 

And I tried to change the permission on the Java on my computer. 

And I can not change the permission. It is a computer at work. Will try on my own laptop.

Python's version and which version of python to use.

Python has two versions on python.org downloads:

https://www.python.org/downloads/


3.6.0 and 2.7.13

3.6.0 is the most recent one.  But 90% of the python code in industry is written in 2.7.X. And there are a lot of modules of python in python 2.

On this python primer, page 4, it also said that a lot of python code was written in python 2.


https://hplgit.github.io/primer.html/doc/pub/half/book.pdf

On youtube, currently, most of the python tutorial is about python 3.

For example, I like the tutorial from this channel, their python tutorial is about python 3.
