我有这个烦人的 M2Crypto 错误：

In [126]: M2Crypto.EVP.load_key('private-key-2048.pem', 'r')
---------------------------------------------------------------------------

    364     bio = m2.bio_new_file(file, 'r')
    365     if bio is None:
--> 366         raise BIO.BIOError(Err.get_error())

如果传递的文件名/对象无法打开，bio_new_file 方法将返回 None。

我会检查“private-key-2048.pem”是否确实存在于预期的路径中，并检查其读取权限。
