Spyder启动失败：字体文件PermissionError问题求助

启动Spyder时卡在初始化环节，通过Anaconda提示符启动时出现如下报错：

PermissionError: [Errno 13] Permission denied: 'C:\Users\user\AppData\Local\Microsoft\Windows\Fonts\codicon.ttf'

环境配置 #

• Anaconda: anaconda命令行客户端（版本1.12.1）
• Windows 11 Home
• Python 3.11

临时解决方案 #

将codicon.ttf和materialdesignicons6-webfont.ttf这两个字体文件剪切到其他目录，系统会自动在原路径生成同名文件，但每次启动Spyder都需要重复执行该操作。

已尝试的自定义修复（未彻底解决） #

修改了shutil.py中的copyfile函数，添加了PermissionError的处理逻辑，同时编写了create_folder_for_special_files函数自动迁移字体文件，但仍需三次启动Spyder才能成功：第一次触发codicon.ttf报错并处理，第二次触发materialdesignicons6-webfont.ttf报错并处理，第三次才能正常启动。

修改后的copyfile函数代码 #

def copyfile(src, dst, *, follow_symlinks=True):
    """Copy data from src to dst in the most efficient way possible.

    If follow_symlinks is not set and src is a symbolic link, a new
    symlink will be created instead of copying the file it points to.

    """
    sys.audit("shutil.copyfile", src, dst)

    if _samefile(src, dst):
        raise SameFileError("{!r} and {!r} are the same file".format(src, dst))

    file_size = 0
    for i, fn in enumerate([src, dst]):
        try:
            st = _stat(fn)
        except OSError:
            # File most likely does not exist
            pass
        else:
            # XXX What about other special files? (sockets, devices...)
            if stat.S_ISFIFO(st.st_mode):
                fn = fn.path if isinstance(fn, os.DirEntry) else fn
                raise SpecialFileError("`%s` is a named pipe" % fn)
            if _WINDOWS and i == 0:
                file_size = st.st_size

    if not follow_symlinks and _islink(src):
        os.symlink(os.readlink(src), dst)
    else:

    return dst

create_folder_for_special_files函数代码 #

from datetime import datetime
import shutil
def create_folder_for_special_files(dst):
    #I made this one myself
    today_date = datetime.now().strftime("%Y-%m-%d")
    new_folder_path = os.path.join("C:\Users\user\Documents\fontstuff", today_date)
    os.makedirs(new_folder_path, exist_ok=True)
    shutil.move(dst, os.path.join(new_folder_path, os.path.basename(dst)))
    return os.path.join(new_folder_path, os.path.basename(dst))

寻求永久解决方法 #

需要找到能彻底解决该字体文件权限问题的方案，无需每次启动Spyder重复操作或多次启动才能进入程序。
