导致npm生成问题/错误的浏览器列表

标签: javascript json

我的create-react-app无法构建,出现此错误:

./src/index.css
Module build failed: BrowserslistError: Unknown browser query `dead`
    at Array.forEach (<anonymous>)

我检查了package-lock.json并更新了所有依赖于浏览器列表的软件包,但是其中一些没有更新到v3以上,我认为这是问题所在,它们是:

-自动前缀 -babel预设环境 -babel预设反应应用 -postcss-merge-rules

我可以只删除这些软件包吗?尽管其他软件包也依赖于它们,但是我还是束手无策,该应用程序运行良好,但无法构建,因此肯定无法在开发服务器上正常工作吗?

我的package.json是:

   {
  "name": "dashboard",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@material-ui/core": "latest",

当您说您经历了程序包锁定并更新了版本时,确定要这样做后再次运行npm install吗?

您可以尝试运行npm update来查看是否可以解决您的问题。

如果仍然不能解决问题,则可以运行npm ls列出所有程序包及其依赖关系,以尝试查找与先前版本的BrowserList相关的程序包,检查版本。该软件包,以检查是否可以更新它,如果不能更新,则可能需要与该软件包的所有者联系
