I want to install python-igraph. I need c/c++ compiler for it, how can I install c compiler in windows for python? and how can I link python-igraph to this compiler? I installed Mingw but then I don't know how should I set variable for it?

edit: I want to run this tool. one of its requirements is installing python-igraph. When I run this file I have the below error:

 File "toplevel.py", line 37
 self.transformation_directory = "C:\Users\aaa\Desktop\Workspace1\test3\backend\generated/transformation"
                                         ^
 SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

some one tell me this is because the c/c++ compiler didn't install in your PC. I also search about this error, but the solutions are depended on I know the source code of this tool. but I didn't know about source code I just change line 6 and 73 of above file.

I use windows 8 (I have the same error on windows vista).

My system Path variable is:

C:\Program Files\Java\jdk1.7.0_79\bin;C:\Users\aaa\AppData\Local\Programs\Python\Python35;C:\Users\aaa\AppData\Local\Programs\Python\Python35\Scripts;C:\Program Files\pl\bin;

My user path variable is:

C:\Program Files\Java\jdk1.7.0_79\bin

  • @NetVicious I asked another question. I have a problem with installing c compiler, not python-igraph. I installed python-igraph, but it seems it doesn't work correctly. – viol Apr 28 '17 at 10:56
  • Ok, the question was not very good writed so. What variable you're talking about. The path variable you should modify? Which Windows version are you running? – NetVicious Apr 28 '17 at 10:59
  • @NetVicious thanks. I edit my question. – viol Apr 28 '17 at 16:03

In python you should use double backslash for path delimiters.

You're receiving that message because \U it's used for extended Unicode codepoint escape.

Try with this:

self.transformation_directory = "C:\\Users\\aaa\\Desktop\\Workspace1\\test3\\backend\\generated\\transformation"
