将 Gatsby 博客部署到 Netlify 时出错

【中文标题】将 Gatsby 博客部署到 Netlify 时出错

【英文标题】：Got error when deploying Gatsby blog to Netlify

【发布时间】：2020-05-25 15:10:42

【问题描述】：

我在 Netlify 上部署了我的 Gatsby 博客，但遇到了几个问题。

问题 - 当我运行“gatsby develop”时，即使有错误消息，我也可以看到博客文章。 - 但是，当我运行“gatsby build”时，错误会停止处理。 - 我成功部署并删除了“gatsby-node.js”中的内容。 - 我可以看到已部署的网页，但不知何故，通过 Contentful 管理的博客帖子不起作用。 - 如果我使用“gatsby-node.js”中的内容进行部署，它会失败并且不起作用。

观察 - 由于“gatsby-node.js”用于创建帖子，这会影响我的博客页面。 - 如果我保持原样，它会返回一条错误消息，说“TypeError：无法读取未定义的属性'替换'”。 - 相信这不是内容问题，因为我可以通过开发环境看到所有帖子。

预期结果 - 在网页上显示帖子。

如果您能分享解决问题的想法/想法，我们将不胜感激。

【参考方案1】：

外人很难调试您的代码。

我建议删除代码：

从 gatsby-node.js 中删除所有代码 将代码添加到您的gatsby-node.js 并构建您的项目，直到遇到错误。 这很耗时，但可能是必要的。那么至少你知道罪魁祸首是什么。

提示您的gatsby-config.js 也可能有问题。仔细检查您的 gatsby-source-filesystem 插件。
