安装WeasyPrint后，我收到此错误：“Django中出错：OSError：dlopen（）无法加载库：cairo / cairo-2”
以下是所有细节：
;WITH cte
AS (SELECT CASE
WHEN val IS NOT NULL
AND Row_number()OVER(partition BY val ORDER BY ord) = 1 THEN val
ELSE NULL
END val,
ord
FROM Yourtable
CROSS apply (VALUES ([B11_1_siknr],1),([B11_2_siknr],2),([B12_siknr],3),([B21_siknr],4),
([B22_1_siknr],5),([B22_2_siknr],6),([B31_siknr],7),([B32_siknr],8),
([B41_siknr],9),([B42_siknr],10))tc (val, ord))
SELECT B11_1_siknr = [1],
B11_2_siknr = [2],
...
FROM cte
PIVOT (Max(val)
FOR ord IN ([1],[2],[3],[4],[5],[6],[7],[8],[9],[10]))pv
我在Stackoverflow上找到了类似问题的解决方案：Getting "OSError: dlopen() failed to load a library: cairo / cairo-2" on Windows。正如那里所建议的那样，我从http://win32builder.gnome.org/下载了一个名为GTK + Bundle 3.10.4的软件包。我按照那里提到的说明。但仍然出现错误。
我还在这里找到了另一个可能的解决方案：dlopen() failed to load a library: cairo / cairo-2
我已在我的电脑中安装了Choco，并在命令提示符下运行了以下命令。

现在，我收到了这些错误：
choco install libcairo2
我完全陷入困境。请帮我。我正在做一个关于建立在线商店的Django课程。除非我解决这个问题，否则我无法继续。所以，我非常需要帮助。
