“BABEL_ENV”未被识别为内部或外部命令

Question

我正在本地环境中设置 PWA，并关注https://webkul.com/blog/magento2-3-pwa-studio-setup/this。

运行“yarn run build”命令时，卡在 “BABEL_ENV”处不被识别为内部或外部命令

我已经在全球安装了 babel。

我浏览了很多博客，但找不到解决方案。任何帮助将被appriciated。

$ yarn run build
yarn run v1.15.2
$ yarn workspaces run build
$ echo 'Skipping graphql-cli-validate-magento-pwa-queries build...'
'Skipping graphql-cli-validate-magento-pwa-queries build...'
$ concurrently --raw yarn:build:cjs yarn:build:esm
$ BABEL_ENV=production babel src --out-dir dist --root-mode 'upward' --source-maps
$ BABEL_ENV=development babel src --out-dir esm --root-mode 'upward' --source-maps
'BABEL_ENV' is not recognized as an internal or external command,

他们已经意识到这个问题并正在努力解决它：

https://github.com/magento-research/pwa-studio/pull/899

这是 PWA 工作室package.json脚本的问题。它们是为 Unix 编写的，因为它们依赖于以 Unix 方式设置 env 变量，例如BABEL_ENV=... command.

修复这些脚本的一种方法是使用cross-envpackage 并更改它：

BABEL_ENV=production babel src --out-dir dist --root-mode 'upward' --source-maps

对此：

cross-env BABEL_ENV=production babel src --out-dir dist --root-mode 'upward' --source-maps
