现象描述
下载或更新 Provider 出现如下报错信息：
Initializing the backend...Initializing provider plugins...- Finding latest version of tencentcloudstack/tencentcloud...╷│ Error: Failed to install provider││ Error while installing tencentcloudstack/tencentcloud v1.78.5: could not query provider registry for registry.terraform.io/tencentcloudstack/tencentcloud: failed to retrieve authentication checksums for provider: the request failed after 2 attempts, please try again later: Get│ "https://github.com/tencentcloudstack/terraform-provider-tencentcloud/releases/download/v1.78.5/terraform-provider-tencentcloud_1.78.5_SHA256SUMS": context deadline exceeded╵
或者下载很慢：

问题定位
Terraform 的默认镜像源
registry.terraform.io 部署在国外，在国内拉取镜像时可能存在网络问题导致拉取速度慢、甚至无法成功拉取。为解决此问题，您可以使用腾讯云提供的 镜像源。操作步骤
创建 Terraform CLI 配置文件
按需创建
.terraformrc 或 terraform.rc 配置文件，您可以将其与其他配置文件放在一个文件夹内，位置取决于主机操作系统：在 Windows 上，该文件必须命名
terraform.rc，并放置在相关用户的 %APPDATA% 目录中。该目录的物理位置取决于您的 Windows 版本和系统配置；可以在 PowerShell 中使用 $env:APPDATA 查找其在系统上的位置。在所有其他系统上，文件必须命名
.terraformrc，并直接放在相关用户的 home 目录中。Terraform CLI 配置文件的位置也可以使用 TF_CLI_CONFIG_FILE 环境变量来指定。任何此类文件都应遵循命名模式 *.tfrc，详情见 Terraform 官网指引。以 MacOS 为例，创建
.terraformrc 文件在用户的 home 目录下，内容如下：provider_installation {network_mirror {url = "https://mirrors.tencent.com/terraform/"// 限制只有腾讯云相关Provider, 从url中指定镜像源下载include = ["registry.terraform.io/tencentcloudstack/*"]}direct {// 声明除了腾讯云相关Provider, 其它Provider依然从默认官方源下载exclude = ["registry.terraform.io/tencentcloudstack/*"]}}
运行 terraform init
在您保存 Terraform 配置文件的目录下，执行
terraform init 命令初始化配置。此步骤中，Terraform 会自动检测配置文件中的 provider 字段，并下载最新版本的模块和插件。若打印如下信息，则表示初始化成功。
