将资源都放在与脚本同级的一个文件夹下，脚本会进行xxtea解密和astc转换，时间会有点长，依赖就Pillow和texture2ddecoder

大佬，太感谢你了。
这是没下载依赖麽
终端执行pip install Pillow
C:\Users\admin>pip install Pillow
Fatal error in launcher: Unable to create process using ‘“d:\huanjin\python.exe” “D:\huanjin\Scripts\pip.exe” install Pillow’: ???
你这是环境有问题啊
python -m install Pillow
这样执行我看看
C:\Users\admin>python -m install Pillow
D:\python\python.exe: No module named install
python -m pip install Pillow
试试，通宵完脑子抽风，忘记加pip了（
C:\Users\admin\Desktop\gx>python 123.py
Traceback (most recent call last):
File “C:\Users\admin\Desktop\gx\123.py”, line 6, in
import texture2ddecoder
ModuleNotFoundError: No module named ‘texture2ddecoder’
这个依赖要怎么安装 
你这，要么去映射表还原名称，要么用我那个资源列表来下（
import os
import requests
from urllib.parse import urlparse
from tqdm import tqdm
from multiprocessing import Pool
output_folder = 'resource'
if not os.path.exists(output_folder):
os.makedirs(output_folder)
num_processes = 256
download_list = []
with open('light_gap_interpretation_TW_list.txt', 'r', encoding='utf-8') as file:
for line in file:
parts = line.strip().split('<')
if len(parts) == 3:
url, location, size = parts
download_list.append((url.strip(), location.strip(), int(size)))
def download_file(url_location_size):
url, location, size = url_location_size
filename = os.path.join(output_folder, location)
if not os.path.exists(filename) or os.path.getsize(filename) != size:
if not os.path.exists(os.path.dirname(filename)):
os.makedirs(os.path.dirname(filename))
print(f"Downloading {location}...")
response = requests.get(url, stream=True)
with open(filename, 'wb') as file, tqdm(
desc=location, total=size, unit="B", unit_scale=True) as bar:
for data in response.iter_content(chunk_size=1024):
file.write(data)
bar.update(len(data))
return size
else:
print(f"Skipping {location} (already exists)")
return 0
if __name__ == '__main__':
total_size = 0
with Pool(num_processes) as pool:
results = pool.map(download_file, download_list)
total_downloaded = sum(1 for result in results if result > 0)
total_size = sum(results)
print(f"Downloaded {total_downloaded} files with a total size of {total_size / (1024 * 1024):.2f} MiB")
大佬这个资源列表怎么用，我把代码保存py跟资源列表放一起，运行他会闪退
