Question

我正在尝试将Node js应用程序部署到Heroku，但是它一直失败。

我已经设置了NPM_CONFIG_PRODUCTION=false。构建脚本在我的本地计算机上工作正常

这是我的package.json文件

"release": "npm run clean && npm run build-app && npm run start",
    "clean": "rm -rf dist && mkdir dist",
    "build": "rm -rf ./dist && mkdir dist && babel . --out-dir dist",
    "build-app": "babel . -s -d dist --presets=@babel/env --ignore node_modules",

构建应该成功，但这是我在Heroku上遇到的错误

> rm -rf ./dist && mkdir dist && babel . --out-dir dist

Answer 1

错误似乎是由于我的构建脚本中的.标志告诉babel转换我的node_modules文件夹，即使使用--ignore node_modules标志也由于某些尚不明确的原因而拒绝为我工作。我必须重组整个文件夹，才能将node_modules文件夹移到babel脚本的范围之外，以使其最终正常运行
