What is a <versionspec> inspection error in PyCharm?

Question

Trying to build a program that uses a request file from a user. When I try to parse that file named POST.txt I get an error:

<versionspec>, RequirementsTokenType.COMMENT, RequirementsTokenType.EOL, RequirementsTokenType.LSBRACE, RequirementsTokenType.SEMICOLON or RequirementsTokenType.WHITE_SPACE expected, got '/'

Looks like it interperts the request file as requirements file, but I have no idea why, I simply pasted a request from burpsuite and saved to a .txt file. Until now, when I worked with requests files it worked well.

Here is the request:

POST /forum/ HTTP/1.1
Host: localhost
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0

That's what my program looks like until now (Can't really move further if my request file is not parsed):

import argparse
import requests
import Burpee.burpee as burp
import re

MARKER = input("What are the markers for the variables (Default: '$'): ") or '$'

parser = argparse.ArgumentParser(description = 'sniper.py, Allows 1 set of payloads, runs by order '
                                               'in all the marked positions, one at a time.')
parser.add_argument('request_file', help = 'Request file with marked variables (POST or GET)')

args         = parser.parse_args()
request_file = args.request_file

headers, POST_data = burp.parse_request(request_file)
METHOD = burp.get_method_and_resource(request_file)[0]  # Sets METHOD (POST \ GET)

marked_vars = []
with open(request_file, 'r') as request_f:
    lines = request_f.readlines()
    for line in lines:
        marked = re.findall('\$(.*?)\$', line)
        for var in marked:
            marked_vars.append(var)
    print(marked_vars)

destination = burp.get_method_and_resource(request_file)[1]  # Where the referer sends the request

And + the inspection error I get in PyCharm:

<versionspec>, RequirementsTokenType.COMMENT, RequirementsTokenType.EOL, RequirementsTokenType.LSBRACE, RequirementsTokenType.SEMICOLON or RequirementsTokenType.WHITE_SPACE expected, got '/'

Haven't seen this inspection in my life. How can I solve this issue?

Answer 1

I'm having the same issue with a text file but apparently PyCharm doesn't recognize '.txt' extension.

Try creating a new file with no extension and then try to parse it.

It worked for me, so let me know if this works for you.

Answer 2

To get Pycharm to stop complaining you have to right click the file and override the file type.

You will want to choose "Plain Text" - it will no longer provide syntax help.
