使用流项目为 javascript 运行 react-codemod 时出错

Question

使用流在 javascript 项目中运行时遇到错误。

npx react-codemod rename-unsafe-lifecycles

如何让这个 codemod 正常运行。这是将项目的 React 版本升级到 16.9+ 所必需的

使用 jscodeshift 和 --no-babel 标志为我工作，而不是 npx 包。似乎 npx react-codemod 现在不接受任何标志：

jscodeshift --no-babel --parser=flow -t /path/to/react-codemod/transforms/class.js /path/to/src
