## Problem: `tonsdk` Installation Appears Corrupt - `__init__.py` is 0KB
**Description:**
After attempting to install `tonsdk` using `pip`, the library appears to be corrupt or incomplete on my Windows system. Specifically, the crucial `__init__.py` file within the `tonsdk` package directory is consistently found to be **0KB in size**.
This issue persists even after multiple attempts to clean, reinstall, use virtual environments, and disable antivirus software. The installation command reports success, but the library is not functional.
**Symptoms:**
1. **`tonsdk version (from __version__): No disponible`**: The `__version__` attribute for the `tonsdk` package is not found, indicating the `__init__.py` file is not being loaded or is empty.
2. **`'Cell' object has no attribute 'hash_'` error**: When attempting to use core `tonsdk` functionalities, specifically the **`hash_` property of the `Cell` object** (e.g., from `tonsdk.boc.Cell`), this attribute is missing, leading to a runtime error. This strongly indicates that the `Cell` class or its implementation is not loaded correctly due to the corrupted installation.
3. **Inconsistent Wallet Code Hashes**: When comparing a generated V4R2 wallet (`Hash de Code B`) with a known good reference wallet (`Hash de Code A`), the code hashes are consistently different. This implies that the `tonsdk` library is not using the expected or correct wallet code definitions, despite the data hashes matching, pointing to a corrupted or non-standard `tonsdk` installation.
* `Hash de Code A: 83a22325407c8161fea0968aab944876656ad09626429a0e0ec42acf89748873`
* `Hash de Code B: 8a3e04432d90139709770e99742a4fb03efd87544643a45107af2fa615700fac`
4. **Program Termination:** The script eventually terminates with messages like "El subproceso 'MainThread' (1) terminó con código 0 (0x0). El programa 'python.exe' terminó con código 4294967295 (0xffffffff)." (This is the Spanish output for a program exiting with an error code).
**Steps to Reproduce:**
1. **Create a new Python virtual environment:**
```bash
python -m venv my_ton_env
```
2. **Activate the virtual environment:**
```bash
.\my_ton_env\Scripts\activate
```
3. **Install `tonsdk` using forced reinstallation and no-cache option:**
```bash
pip install --no-cache-dir --force-reinstall tonsdk
```
* **Expected:** `Successfully installed tonsdk-1.0.15` and a fully functional library.
* **Actual:** `Successfully installed tonsdk-1.0.15` is reported, but the library is not functional as verified in the next steps.
4. **Verify `__init__.py` file size after installation:**
Navigate to `C:\Users\YourUser\YourProjectFolder\my_ton_env\Lib\site-packages\tonsdk\`
* **Expected:** `__init__.py` to be > 0KB (e.g., 1KB or more), containing Python code.
* **Actual:** `__init__.py` is **0KB**.
5. **Run a Python script that imports `tonsdk` and attempts to use `Cell.hash_` (e.g., a wallet generation/comparison script):**
```python
# Example snippet from the affected script:
import tonsdk
import os
from tonsdk.boc import Cell
# ... other tonsdk imports and your wallet generation code ...
print(f"tonsdk version (from __version__): {getattr(tonsdk, '__version__', 'No disponible')}")
print(f"tonsdk path: {os.path.dirname(tonsdk.__file__)}")
# ... later in the code where Cell.hash_ is accessed ...
# This line consistently triggers the `'Cell' object has no attribute 'hash_'` error
some_cell_instance.hash_
```
**Environment:**
* **Operating System:** Windows 11 (64-bit)
* **Python Version:** 3.11.7 (tags/v3.11.7:fa7a6f2, Dec 4 2023, 19:24:49) [MSC v.1937 64 bit (AMD64)]
* **`tonsdk` Version Attempted:** 1.0.15
* **`pip` Version:** (Please provide the output of `pip --version` here)
* **Antivirus/Security Software:** (Mention if you use one, e.g., Windows Defender, Avast, Norton, and whether temporarily disabling it during installation attempts had any effect).
**Troubleshooting Steps Already Attempted:**
* Deactivated `App Execution Aliases` for Python in Windows Settings.
* Modified system `PATH` environment variable to prioritize `C:\Program Files\Python311`.
* Uninstalled `tonsdk` and other related TON libraries (`ton`, `tonclient`, `toncli`) globally.
* Manually deleted `tonsdk` and related folders from `site-packages` (both global `C:\Program Files\Python311\Lib\site-packages\` and virtual environments).
* Used multiple fresh Python virtual environments for installation attempts.
* Performed `pip install --no-cache-dir --force-reinstall tonsdk` multiple times within active virtual environments.
* Rebooted the system multiple times to clear any file locks/caches before installation attempts.
* Temporarily **disabled antivirus software** during the entire installation process (deleting old venv, creating new venv, `pip install`).
The persistent 0KB `__init__.py` strongly suggests a fundamental issue with the package's integrity upon download or its writing to the file system on my specific setup.
