运行 terraform init、terraform plan 或 apply 时出现无效字符错误

Question

我正在使用 VScode 编辑器运行 Terraform，该编辑器使用 PowerShell 作为默认 shell，当我尝试验证它或通过 VScode、外部 PowerShell 或 CMD 运行 terraform init/plan/apply 时遇到相同的错误。

在我添加虚拟机创建代码之前，代码运行没有任何问题。我已经合并了 variables.tf、terraform.tfvars 和下面的主要 Terraform 代码。

terraform.tfvars

web_server_location       = "West US 2"
resource_prefix           = "web-server"
web_server_address_space  = "1.0.0.0/22"
web_server_address_prefix = "1.0.1.0/24"
Environment               = "Test"

variables.tf

variable "web_server_location" {
  type = string
}

variable "resource_prefix" {
  type = string
}

variable "web_server_address_space" {
  type = string
}

#variable for network range

variable "web_server_address_prefix" {
  type = string
}

#variable for Environment
variable "Environment" {
  type = string
}

错误：

PS C:\Users\e5605266\Documents\MyFiles\Devops\Terraform> terraform init

There are some problems with the configuration, described below.

The Terraform configuration must be valid before initialization so that
Terraform can determine which modules and providers need to be installed.

Answer 1

我自己在几种不同的情况下都遇到过这个问题，它确实有一个根本不好玩的通用解决方案：手动将代码重新输入...

这个资源块似乎是它遇到问题的地方：

resource "azurerm_virtual_machine" "example_windows_vm" {
  name  = "${var.resource_prefix}-VM"
  location = azurerm_resource_group.example_rg.location
  resource_group_name = azurerm_resource_group.example_rg.name
  network_interface_ids = [azurerm_network_interface.example_nic.id]
  vm_size = "Standard_B1s"
  delete_os_disk_on_termination = true

  storage_image_reference {
    publisher = "MicrosoftWindowsServer"
    offer     = "WindowsServerSemiAnnual"
    sku       = "Datacenter-Core-1709-smalldisk"
    version   = "latest"  
  }

  storage_os_disk  {
    name                 = "myosdisk1"
    caching              = "ReadWrite"
    create_option        = "FromImage"
    storage_account_type = "Standard_LRS"
  }

  os_profile {
    computer_name  = "hostname"
    admin_username = "adminuser"
    admin_password = "Password1234!"
  }

  os_profile_windows_config {
    disable_password_authentication = false
  }

  tags = {
    environment = "Test"
  }
}

尝试按原样将其复制回您的编辑器。我在其中看不到任何有问题的字符，具有讽刺意味的是，StackOverflow 可能已经完成了您的工作并将它们过滤掉了。从字面上复制/粘贴到现有块上可能会解决这种情况。

我已经多次在网上看到带有时尚双引号（不是 ASCII 双引号并且不起作用）的 Terraform 示例。这可能就是您所看到的。

除此之外，您还需要将代码推送到 GitHub 或类似网站，以便我自己查看原始字节。

Answer 2

这可能有助于遇到此错误并在 Google 上遇到此错误的人，我只是想我会发布我的情况以及我如何解决它。

我有一个旧的演示 Terraform 基础设施，几个月后我重新访问了它，长话短说，我在两天前发出了这个命令并忘记了它：

terraform plan -out=plan.tf

这将创建计划的 zip 存档。两天后回来并运行 terraform init 时，我的终端滚动垃圾和“该字符未在该语言中使用”。约 7 秒。由于 .tf 扩展名，terraform 正在查看 zip 数据并立即大便。

通过将单个 tf 文件移动到临时目录并使用 terraform init 检查它们的有效性，我找到了罪魁祸首，将其删除，并恢复了功能。

各位，导出计划文件时要小心！

Answer 3

我遇到了同样的问题并找到了这个页面。

我解决了这个问题并决定在这里发帖。 我在 Notepad++ 中打开了我的计划文件并选择了查看-显示所有符号。 我删除了所有 TAB 字符并用空格替换它们。 就我而言，这个问题完全解决了。
