无法从端点下载 GraphQL 架构

Question

我目前正在使用 graphql-cli from Prisma 从端点下载架构。但是，即使我部署了对模式所做的更改（部署成功），每当我尝试下载模式时，我都会得到 project prisma - No changes。并且生成的 prisma.graphql 保持不变。

我使用以下命令下载架构：

graphql get-schema -p prisma --dotenv config/dev.env

dev.env简单来说就是获取PRISMA_ENDPOINT=http://localhost:4466/环境变量。

我尝试通过在 prisma.yml 中添加以下内容以不同的方式生成 prisma.graphql：

endpoint: ${env:PRISMA_ENDPOINT}
datamodel: datamodel.prisma
generate:
   - generator: graphql-schema
     output: ./generated/

并执行prisma generate，但我得到错误：

▸ [WARNING] in /Users/F/Documents/d/server/prisma/prisma.yml: A valid environment ▸ variable to satisfy the declaration 'env:PRISMA_ENDPOINT' could not be found.

尝试停止并重新创建 Docker 以及删除 node_module 并重新安装，但无济于事。

我的package.json:

要修复调用 prisma generate 时的错误 "variable to satisfy the declaration 'env:PRISMA_ENDPOINT' could not be found."，您应该手动设置 PRISMA_ENDPOINT 变量或通过 dotenv 加载它。例如，您可以运行 npx dotenv -- prisma generate 从您的 .env 文件加载环境变量。

要通过 graphql get-schema 从端点下载架构，请确保提供正确配置的 .graphqlconfig.yml 并提供正确的项目。 Prisma 项目的示例配置可能如下所示：

projects:
  prisma:
    schemaPath: 'src/schema.graphql'
    extensions:
      endpoints:
        default: 'http://localhost:4000/graphql'
  database:
    schemaPath: 'src/generated/prisma.graphql'
    extensions:
      prisma: 'database/prisma.yml'
      endpoints:
        default: 'http://localhost:4466'
