Gatsby 站点的 Netlify 构建失败

Question

我正在尝试使用博客部署我的第一个 gatsby 站点，但它总是失败。我更新了我所有的依赖项，但现在我无法弄清楚到底是什么问题。

我真的很感激任何建议，它已经困扰我好几天了。在此之前，我遇到了一堆 npm 错误，所以我更新了所有我认为可以解决问题的依赖项。

仅供参考，我正在为博客使用内容丰富的 cms

这里好像构建失败了：

BlogElements.js 文件只是一个样式化组件：

import styled from 'styled-components';



export const Styledh2 = styled.h2`
  color: purple;
`;

export const StyledBox = styled.li`
 
    width: 500px;
    background-color: lightblue;
    float: left

`

export const StyledLink = styled.div`
    background-color: yellow;
    position: relative;
    left: 3rem;
    justify-content: space-around
`

您的问题出现是因为 BlogElements 存储在 /pages 文件夹下，因此 Gatsby 试图根据该文件夹结构创建 URL 路径。由于您没有返回有效的 React 组件，因此您的代码有问题。

如果您仅将 BlogElements 用于样式目的，请将其移动到其他位置（例如，在 /src/components/styles 下）并在需要的任何地方导入它。

/pages 下的有效样式组件应如下所示：

import React from "react"
import styled from "styled-components"

const Container = styled.div`
  margin: 3rem auto;
  max-width: 600px;
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: center;
`

const UserWrapper = styled.div`
  display: flex;
  align-items: center;
  margin: 0 auto 12px auto;
  &:last-child {
    margin-bottom: 0;
  }
`

const Avatar = styled.img`
  flex: 0 0 96px;
  width: 96px;
  height: 96px;
  margin: 0;
`

const Description = styled.div`
  flex: 1;
  margin-left: 18px;
  padding: 12px;
`

const Username = styled.h2`
  margin: 0 0 12px 0;
  padding: 0;
`

const Excerpt = styled.p`
  margin: 0;
`

const User = props => (
  <UserWrapper>
    <Avatar src={props.avatar} alt="" />
    <Description>
      <Username>{props.username}</Username>
      <Excerpt>{props.excerpt}</Excerpt>
    </Description>
  </UserWrapper>
)

export default function UsersList() {
  return (
    <Container>
      <h1>About Styled Components</h1>
      <p>Styled Components is cool</p>
      <User
        username="Jane Doe"
        avatar="https://s3.amazonaws.com/uifaces/faces/twitter/adellecharles/128.jpg"
        excerpt="I'm Jane Doe. Lorem ipsum dolor sit amet, consectetur adipisicing elit."
      />
      <User
        username="Bob Smith"
        avatar="https://s3.amazonaws.com/uifaces/faces/twitter/vladarbatov/128.jpg"
        excerpt="I'm Bob smith, a vertically aligned type of guy. Lorem ipsum dolor sit amet, consectetur adipisicing elit."
      />
    </Container>
  )
}

请注意，上面的示例片段将 UsersList 导出为 React 组件，这与您的 BlogElements 不同。

在将项目推送到 Netlify 之前尝试在本地构建项目以避免出现错误。
