出现以下错误：

error: Running program '/builds/infra/gcp/gke' failed with an unhandled exception:
TSError: ⨯ Unable to compile TypeScript:
iam.ts(12,34): error TS2694: Namespace '"/builds/infra/gcp/gke/node_modules/@pulumi/gcp/index"' has no exported member 'serviceAccount'.
iam.ts(20,28): error TS2339: Property 'serviceAccount' does not exist on type 'typeof import("/builds/infra/gcp/gke/node_modules/@pulumi/gcp/index")'.

这也是sa的代码：

export class GServiceAccount extends pulumi.ComponentResource {
    public readonly account: gcp.serviceAccount.Account;

    constructor(
        name: string,
        args: GServiceAccountArgs,
        opts?: pulumi.ResourceOptions
    ) {
        super("nakhoda:GServiceAccount", name, {}, opts);
        const sa = new gcp.serviceAccount.Account(
            name,
            {
                accountId: name
            },
            { parent: this }
        );
        this.account = sa;

        args.roles.map(
            r =>
                new gcp.projects.IAMMember(
                    `${name}:${r}`,
                    {
                        member: pulumi.interpolate`serviceAccount:${sa.email}`,
                        project: "nk-gke01-london",
                        role: r
                    },
                    { parent: this }
                )
        );
        this.registerOutputs({
            account: this.account
        });
    }
}

serviceAccount存在于GKE中，所以我不确定它为什么失败，可能是npm包的问题，或者是它找不到它？

• 检查了官方文件
• 在谷歌上检查类似问题，找不到任何东西
• 已验证SA是否存在且正在工作
