如何解决迁移错误 env: node\r: from Gatbsy-images to Gatsby-plugin-images with gatsby-codemods?

Question

我有大量代码想通过 gatsby-codemods 从 gatsby-image 迁移到 gatsby-plugin-image。我已经关注了他们的文档 here。所以问题是我在项目中使用 yarn 并得到一个 `env: node\r: No such file or directory。我尝试在 vi 中解决这个问题：（我认为这是因为 yarn 在所有系统上都使用 UNIX 行尾）

cd /myPathTo/gatsby-codemods
vi index.js
:set ff=unix 
:x

这是我尝试运行 yarn gatsby-codemods gatsby-plugin-image

时遇到的错误

我该如何解决这个问题？

Answer 1

尝试通过 yarn 安装 jscodeshift 依赖项：

npm install -g jscodeshift

我认为你的问题是因为 yarn doesn't convert Windows line endings。

另一种解决方法是直接调用 node_modules 中的 jscodeshift bin，绕过脚本顶部的 shebang：

node node_modules/.bin/jscodeshift -t
