GIMP脚本在终端中运行时可以找到自定义调色板，而在程序内部时则找不到

我想gimp -if --batch-interpreter python-fu-eval -b 'import sys;sys.path=["."]+sys.path;import colorindex;colorindex.python_colorindex("gimptemp.jpg")' -b 'pdb.gimp_quit(1)'从像这样的脚本内部执行（在终端中运行时效果很好）colorindex = subprocess.run(["/usr/bin/gimp", "-if", "--batch-interpreter", "python-fu-eval", "-b", "import sys;sys.path=['.']+sys.path;import colorindex;colorindex.python_colorindex('gimptemp.jpg')", "-b", "pdb.gimp_quit(1)"])（错误使gimp函数找不到所需的调色板）

错误：

GIMP-Error: Calling error for procedure 'gimp-image-convert-indexed':
Palette 'E-Ink' not found

当我不小心留了-d标志阻止画笔和东西加载时，在终端中出现了相同的问题，但是显然我把它拿掉了，所以idk这次可能阻止调色板加载，尤其是当它在终端中工作时。使用subprocess.Popen并没有改变错误。通过脚本打开gimp时，自定义调色板不会显示在调色板托盘gui中，但是当通过终端运行时，它确实会显示在gui中

这是colorindex.py

import os
from gimpfu import *
def python_colorindex(file):
    image = pdb.gimp_file_load(file, file, run_mode=RUN_NONINTERACTIVE)
    drawable = pdb.gimp_image_get_active_layer(image)
    pdb.gimp_image_convert_indexed(image, 1, 4, 3, FALSE, FALSE, "E-Ink")
    pdb.file_png_save(image, drawable, file, file, 0, 0, 0, 0, 0, 0, 0)
    pdb.gimp_image_delete(image)
    print("Exit")
