如何在 Netlify 上发布带有 gatsby-image 的 gatsby 项目？
How do you publish a gatsby project with gatsby-image on Netlify?
所以我可以在本地构建我的 gatsby 项目没问题，但是当 Netlify 尝试构建时，我得到了错误

这基本上只是告诉我我需要在生产模式下构建才能看到完整的错误，对吧？生产模式很好，因为它在我的本地计算机上。
我正在使用 gatsby-image 和 gatsby-background-image 我听说这可能会导致问题？我尝试添加 gatsby-remark-relative-images and followed the instructions on this blog post 但仍然出现相同的错误
我还为节点版本添加了一个环境变量，但它什么也没做，但我读到它可能对 Netlify 和 Gatsby "Step by Step" guide有用

只要询问您是否要查看任何特定文件
要使用 Netlify+Gatsby 管理图像，您需要安装 gatsby-remark-relative-images 插件。这是因为你需要查询放在目录外的图片（通常assets放在/assets文件夹下）。
来自其文档：
Convert image src(s) in markdown to be relative to their node’s parent
directory. This will help gatsby-remark-images match images outside
the node folder. For example, use with NetlifyCMS.
NOTE: This was built for use with NetlifyCMS and should be considered
a temporary solution until relative paths are supported. If it works
for other use cases then great!
然后，在您的 gatsby-node.js 中，您需要放置以下代码段：
const { fmImagesToRelative } = require('gatsby-remark-relative-images');
exports.onCreateNode = ({ node }) => {
fmImagesToRelative(node);
};
这会获取您的 gatsby-source 插件返回的每个节点，并在找到匹配文件时将 markdown 前部数据中的任何绝对路径转换为相对路径。
下一步是在你的 gatsby-config.js 中设置它。遵循这个结构很重要，将你的 transformer remark 插件放在 gatsby-source-filesystem 之后以避免它们覆盖它。
// gatsby-source-filesystem options here
{
resolve: `gatsby-transformer-remark`,
options: {
plugins: [
// gatsby-remark-relative-images must
// go before gatsby-remark-images
{
resolve: `gatsby-remark-relative-images`,
},
{
resolve: `gatsby-remark-images`,
options: {
// It's important to specify the maxWidth (in pixels) of
// the content container as this plugin uses this as the
// base for generating different widths of each image.
maxWidth: 590,
},
},
],
},
您的问题中未提供的最后一步是在您的 config.yml 中设置上传和图像的路径，应该如下所示：
media_folder: static/assets/images
public_folder: /assets/images
在 Gatsby 中，media_folder 必须设置在 /static 路径下才能被 React 及其组件访问。所以，记住 media_folder 路径，你的 public_folder 路径必须相应地设置。来自 Netlify Gatsby documentation.
Still in the root directory, add a “static” folder. Gatsby will copy
everything in the static folder into the output, so we’ll want to
place the Netlify CMS configuration file as static/admin/config.yml.

只要询问您是否要查看任何特定文件
要使用 Netlify+Gatsby 管理图像，您需要安装 gatsby-remark-relative-images 插件。这是因为你需要查询放在目录外的图片（通常assets放在/assets文件夹下）。
来自其文档：
Convert image src(s) in markdown to be relative to their node’s parent directory. This will help gatsby-remark-images match images outside the node folder. For example, use with NetlifyCMS.
NOTE: This was built for use with NetlifyCMS and should be considered a temporary solution until relative paths are supported. If it works for other use cases then great!
然后，在您的 gatsby-node.js 中，您需要放置以下代码段：
const { fmImagesToRelative } = require('gatsby-remark-relative-images');
exports.onCreateNode = ({ node }) => {
fmImagesToRelative(node);
};
这会获取您的 gatsby-source 插件返回的每个节点，并在找到匹配文件时将 markdown 前部数据中的任何绝对路径转换为相对路径。
下一步是在你的 gatsby-config.js 中设置它。遵循这个结构很重要，将你的 transformer remark 插件放在 gatsby-source-filesystem 之后以避免它们覆盖它。
// gatsby-source-filesystem options here
{
resolve: `gatsby-transformer-remark`,
options: {
plugins: [
// gatsby-remark-relative-images must
// go before gatsby-remark-images
{
resolve: `gatsby-remark-relative-images`,
},
{
resolve: `gatsby-remark-images`,
options: {
// It's important to specify the maxWidth (in pixels) of
// the content container as this plugin uses this as the
// base for generating different widths of each image.
maxWidth: 590,
},
},
],
},
您的问题中未提供的最后一步是在您的 config.yml 中设置上传和图像的路径，应该如下所示：
media_folder: static/assets/images
public_folder: /assets/images
在 Gatsby 中，media_folder 必须设置在 /static 路径下才能被 React 及其组件访问。所以，记住 media_folder 路径，你的 public_folder 路径必须相应地设置。来自 Netlify Gatsby documentation.
Still in the root directory, add a “static” folder. Gatsby will copy everything in the static folder into the output, so we’ll want to place the Netlify CMS configuration file as static/admin/config.yml.
