我得到这个错误时，试图启动mongocrypt上heroku

/app/.heroku/python/lib/python3.10/site-packages/pymongo/daemon.py:140: RuntimeWarning: Failed to start mongocryptd: is it on your $PATH?

下面是Heroku上的完整堆栈跟踪。我正在Heroku上运行一个使用Mongodb字段级加密的应用程序。我不知道如何解决这个问题，我四处寻找，但没有找到构建包或任何东西。有什么想法吗？

@kevinAlbs下面的评论很有帮助，因为我看到设置bypass_auto_encryption=True，起初似乎是为了解决mongocrypt的问题。我在创建MongoClient时在fle_opts中设置了这个，但是通过传递auto encryption只是意味着我无法加密任何数据，即使加密的数据可以检索？

with MongoClient(os.environ.get("MONGO_URI"), auto_encryption_opts=fle_opts) as client:

则这些选项为：

fle_opts = AutoEncryptionOpts(
    kms_providers , keyStore, bypass_auto_encryption=True
)

您可以设置大量选项：

class AutoEncryptionOpts(object):
"""Options to configure automatic client-side field level encryption."""

def __init__(
    self,
    kms_providers: Mapping[str, Any],
    key_vault_namespace: str,
    key_vault_client: Optional["MongoClient"] = None,
    schema_map: Optional[Mapping[str, Any]] = None,
    bypass_auto_encryption: bool = False,
    mongocryptd_uri: str = "mongodb://localhost:27020",
    mongocryptd_bypass_spawn: bool = False,
    mongocryptd_spawn_path: str = "mongocryptd",
    mongocryptd_spawn_args: Optional[List[str]] = None,
    kms_tls_options: Optional[Mapping[str, Any]] = None,
    crypt_shared_lib_path: Optional[str] = None,
    crypt_shared_lib_required: bool = False,
    bypass_query_analysis: bool = False,
    encrypted_fields_map: Optional[Mapping] = None,
) -> None:

也许将mongocryptd_uri设置为不同的地址可以解决这个问题？
我真的是在摸黑问有没有人能帮上忙？
