ERROR: Failed building wheel for Levenshtein Failed to build Levenshtein error: failed-wheel-build-for-install

× Failed to build installable wheels for some pyproject.toml based projects ╰─> Levenshtein ERROR: Failed to install required packages cpanel webmail Set up email on application tool PDF Auto MATCHING LOGIC: EmployeeID, FirstName, MiddleName, LastName NAME-BASED MATCHING If Employee ID is not found in the filename, implement a controlled secondary matching method based on employee name. Example: PDF:

Abel Harry Anthony.pdf

CSV:

10152 | Abel | Harry | Anthony | abel@example.com

The application should identify:

Abel Harry Anthony

and match it with the CSV record. The matching logic can be changed so the application uses any 3 of the 4 CSV fields:

• ID
• First Name
• Middle Name
• Last Name

Input PDF: 10004_Vihang_Wani_SalarySlip_March_2026.pdf

no need to rename the pdf file once it's attached also show dashboard me all attachments before sending email can be built as a Windows desktop application that:

1. Imports an employee CSV.
2. Lets you select a folder containing hundreds/thousands of PDFs.
3. Extracts the Employee ID from each filename.
4. Finds the matching employee in the CSV.
5. Renames the PDF according to a defined format.
6. Shows success, unmatched, duplicate, and error reports.
7. Provides a one-click Windows build that produces a .exe.

For your example:Input: SumitShyamraoTunkikar_0020063_Aug_2026.pdf CSV: 20063 | Sumit | Shyamrao | Tunkikar Output: 20063_Sumit_Shyamrao_Tunkikar.pdf Or Input: Abel Harry Anthony.pdf CSV: 10152 | Abel | Harry | Anthony Output:10152_Abel_Harry_Anthony.pdf Or Input: AbhishekYadav_0020311_Aug_2026.pdf CSV: 20311 | Abhishek | Yadav Output:20311_Abhishek_Yadav.pdf SAFETY Original PDFs are preserved by default. The output is written to a separate folder. Add Naming Templates: Configure rename patterns: add Placeholders: ${employeeid} ${firstname} ${middlename} ${surname} ${month} ${year} Define how renamed pdf should look example: Pattern ${employeeid}${firstname}${surname}SalarySlip${month}${year} Or ${employeeid}${firstname}${middlename}${surname}SalarySlip${month}_${year} Live preview 20311_Abhishek_Yadav_SalarySlip_August_2026.pdf
