我正在升级到 antd v5，但在使用 v4 保留较少文件的变量覆盖时遇到了一些问题

我有多个 less 文件，src/theme其中之一包含以下内容

@import 'antd/lib/style/themes/variable.less';

/* font */
@font: ~'var(--font)';

/* auxiliary colors */
@secondary-color: ~'var(--secondary-color)';
@secondary-color-light: ~'var(--secondary-color-light)';
@primary-color-dark: @primary-7;
@primary-color-light: @primary-5;
@background-color: #f8f8f8;
@shadow-color: rgba(0, 0, 0, 0.09);
@text-color: #656565;
@secondary-text-color: #9d9d9d;
@light-text-color: #bababa;

@secondary-color-bg: @green-1;
@warning-color-bg: @orange-1;
@error-color-bg: @red-1;
@info-color-bg: @blue-1;

/* sizes */
@design-scale: 60 / 70;
@app-bar-height: 60px;

@page-padding: 40px 4vw;
@page-padding-mobile: 30px 15px;

@border-radius-base: 4px;
@border-width-base: 2px;

还尝试primaryColor从 ConfigProvider以下位置 注入ConfigProvider.config({ theme: {primaryColor: '#fa259e'} }); …

我创建了一个脚本来下载youtube视频并在每个期间从中提取图像

屏幕截图视频

def screenshotvideo(url, interval, id, fullduration, title, quality):
    interval = int(interval)
    parsed_t = isodate.parse_duration(fullduration)
    durationseconds=parsed_t.total_seconds()
    iterat=int(durationseconds/int(interval))
    for i in range(0, iterat):
        print(str(id))
        print(str(i))
        print(str(i*interval))
        part(url, time.strftime('%H:%M:%S', time.gmtime(int(i*interval))), "00:00:01", title+"-"+str(id), quality)

部分

def part(url, starttime, duration, name, quality):
    f = os.popen("ffmpeg $(youtube-dl -f "+quality+" -g '"+url+"' | sed 's/.*/-ss "+starttime+" -i &/') -t "+duration+" -c copy "+name+".mp4")
    now = f.read()
    print(now)
    f = os.popen("ffmpeg -i "+name+".mp4 -ss 00:00:00 -vframes 1 "+name+".jpg")
    now = f.read()
    print(now)
    f = os.popen("rm -rf "+name+".mp4") …
