[WinError 3] The system cannot find the path specified

[scottzach1]

The example in tests fails to run throwing a path error.

System Details:

• Windows 10
• Python 3.9 (venv)
• Installed version: 0.5.0

The example in tests fails to run with the following error:

from treeplotter.tree import Node, Tree, create_tree_diagram
root = Node(value=1.0, name=None)

child1 = Node(value=0.5, name=None)
child2 = Node(value=1.0, name=None)
child3 = Node(value=3.0, name="A")
root.children = {child1, child2, child3}
root.children

granchild1 = Node(value=0.5, name=None)
granchild2 = Node(value=3.0, name="B")
granchild3 = Node(value=2.0, name="C")
greatgrandchild = Node(value=1.0, name="D")

child1.add_children([granchild1, granchild2])
child2.add_child(granchild3)
granchild1.add_child(greatgrandchild)


tree = Tree(root=root)

create_tree_diagram(
    tree=tree,
    save_path='/Users/{{USER}}/Downloads',  # also fails with `r"C:\\Users\{{USER}}\Downloads"`
    webshot=True,
    verbose=True
)

Output (obfuscated):

Thanks for filing this issue, @scottzach1! Pretty sure I know what the problem is. Unfortunately I'm quite busy these days (I'm in my last year of university) and I haven't had much time to work on this project, but I'll get to it as soon as I can! 👍

If you'd like to fix it yourself and submit a pull request, I think it should be as simple as changing the second line here:

treeplotter/treeplotter/plotter.py

Lines 23 to 24 in 940e08b

	here = os.path.abspath(os.path.dirname(__file__))
	treant_templates = here + "/templates"

to the following:

treant_templates = os.path.join(here, "templates")

The current line assumes the Mac file path system, and is therefore inconsistent when being appended to a Windows filepath. Very good catch!

I am getting similar error but the error is not though by python , It is coming from js I think.

Done ✔
'C://Users//hp//Documents//Projects//spx'
>>>

I have tried all possible ways of writing path:

mypath="C:\\Users\\hp\\Documents\\Projects\\spx"

or

mypath="C:/Users/hp/Documents/Projects/spx"

or

mypath="C://Users//hp//Documents//Projects//spx"

PS:
I am on Windows 10 and Python 3.8
