Question

我正在关注Lynda.com的教程＆＃39;部署一个完整的反应应用程序＆＃39;。我正在使用＆＃39; create-react-app项目来支撑我的项目。由于某些未知原因，我的应用无法访问api，我可以直接访问该API而不会在浏览器上出现任何问题。这是我的package.json文件，每当我运行＆＃39;纱线开始时我都会收到错误。

Answer 1

更新这两行：

"start": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjazdk3jg0yj70197193cltrf && node scripts/start.js",
"build": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjazdk3jg0yj70197193cltrf && node scripts/build.js",

有这两行：

"start": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjazdk3jg0yj70197193cltrf&&node scripts/start.js",
"build": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjazdk3jg0yj70197193cltrf&&node scripts/build.js",

&&之间和周围不应有空格。如果这可以解决您的问题，请将其标记为正确答案

Answer 2

您是如何创建服务的？

看起来你可能只在本地创建了它。

https://api.graph.cool/relay/v1/cjazdk3jg0yj70197193cltrf确实没有有效的GraphQL端点，它不存在。

修改

更新这两行

"start": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjazdk3jg0yj70197193cltrf && node scripts/start.js", "build": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjazdk3jg0yj70197193cltrf && node scripts/build.js",

到

"start": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjb223en111od0191dzu1vba4 && node scripts/start.js", "build": "set GRAPHQL_ENDPOINT=https://api.graph.cool/relay/v1/cjb223en111od0191dzu1vba4 && node scripts/build.js",

当您删除项目cjazdk3jg0yj70197193cltrf时，端点也被删除了。

尝试从react应用程序连接到graphcool中继API时出现此错误：模块构建失败：错误：无有效的GraphQL端点
