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，会出现相同的错误。

\n\n

在我添加虚拟机创建代码之前，代码运行没有任何问题。我已经将 Variables.tf、terraform.tfvars 和下面的主要 Terraform 代码组合在一起。

我自己在几个不同的环境中遇到过这个问题，它确实有一个通用的解决方案，但一点也不有趣：手动输入代码......

\n\n

这个资源块似乎是遇到问题的地方：

\n\n

resource "azurerm_virtual_machine" "example_windows_vm" {\n  name  = "${var.resource_prefix}-VM"\n  location =\xc2\xa0azurerm_resource_group.example_rg.location\n  resource_group_name\xc2\xa0=\xc2\xa0azurerm_resource_group.example_rg.name\n  network_interface_ids\xc2\xa0=\xc2\xa0[azurerm_network_interface.example_nic.id]\n  vm_size =\xc2\xa0"Standard_B1s"\n  delete_os_disk_on_termination = true\n\n  storage_image_reference\xc2\xa0{\n    publisher\xc2\xa0=\xc2\xa0"MicrosoftWindowsServer"\n    offer     = "WindowsServerSemiAnnual"\n    sku\xc2\xa0      =\xc2\xa0"Datacenter-Core-1709-smalldisk"\n    version   =\xc2\xa0"latest"  \n  }\n\n  storage_os_disk\xc2\xa0 {\n    name                 = "myosdisk1"\n    caching\xc2\xa0             =\xc2\xa0"ReadWrite"\n    create_option        = "FromImage"\n    storage_account_type\xc2\xa0=\xc2\xa0"Standard_LRS"\n  }\n\n  os_profile {\n    computer_name  = "hostname"\n    admin_username = "adminuser"\n    admin_password = "Password1234!"\n  }\n\n  os_profile_windows_config {\n    disable_password_authentication = false\n  }\n\n  tags = {\n    environment = "Test"\n  }\n}\n

尝试将其按原样复制回编辑器中。我在其中看不到任何有问题的字符，具有讽刺意味的是，StackOverflow 可能已经为您提供了坚实的基础并将其过滤掉。从字面上将其复制/粘贴到现有块上可以解决这种情况。

\n\n

我在网上多次看到带有时尚双引号的 Terraform 示例（不是 ASCII 双引号，因此不起作用）。这可能就是你所看到的。

\n\n

除此之外，您需要将代码推送到 GitHub 或类似的地方，以便我自己可以看到原始字节。

Answer 2

偶尔这会帮助那些遇到这个错误并在谷歌上遇到它的人，我只是想我会发布我的情况以及我如何修复它。

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，我两天前发出了这个命令，然后忘记了它：

terraform plan -out=plan.tf

这将创建该计划的 zip 存档。两天后回来并运行 terraform init 时，我的终端滚动了垃圾信息并显示“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 数据并立即拉裤子。

通过将各个 tf 文件移动到临时目录并使用terraform init检查其有效性，我找到了罪魁祸首，将其删除，并且功能已恢复。

伙计们，导出计划文件时要小心！
