10:52:56 PM: There might be a problem with the project dependency tree.
10:52:56 PM: It is likely not a bug in Create React App, but something you need to fix locally.
10:52:56 PM: The react-scripts package provided by Create React App requires a dependency:
10:52:56 PM: "babel-jest": "23.6.0"
10:52:56 PM: Don't try to install it manually: your package manager does it automatically.
10:52:56 PM: However, a different version of babel-jest was detected higher up in the tree:
10:52:56 PM: /opt/build/repo/node_modules/babel-jest (version: 24.7.1)
10:52:56 PM: Manually installing incompatible versions is known to cause hard-to-debug issues.
10:52:56 PM: If you would prefer to ignore this check, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
10:52:56 PM: That will permanently disable this message but you might encounter other issues.
10:52:56 PM: To fix the dependency tree, try following the steps below in the exact order:
10:52:56 PM: 1. Delete package-lock.json (not package.json!) and/or yarn.lock in your project folder.
10:52:56 PM: 2. Delete node_modules in your project folder.
10:52:56 PM: 3. Remove "babel-jest" from dependencies and/or devDependencies in the package.json file in your project folder.
10:52:56 PM: 4. Run npm install or yarn, depending on the package manager you use.
10:52:56 PM: In most cases, this should be enough to fix the problem.
10:52:56 PM: If this has not helped, there are a few other things you can try:
10:52:56 PM: 5. If you used npm, install yarn (http://yarnpkg.com/) and repeat the above steps with it instead.
10:52:56 PM: This may help because npm has known issues with package hoisting which may get resolved in future versions.
10:52:56 PM: 6. Check if /opt/build/repo/node_modules/babel-jest is outside your project directory.
10:52:56 PM: For example, you might have accidentally installed something in your home folder.
10:52:56 PM: 7. Try running npm ls babel-jest in your project folder.
10:52:56 PM: This will tell you which other package (apart from the expected react-scripts) installed babel-jest.
10:52:56 PM: If nothing else helps, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
10:52:56 PM: That would permanently disable this preflight check in case you want to proceed anyway.
10:52:56 PM: P.S. We know this message is long but please read the steps above :-) We hope you find them helpful!
所以我最近将新构建推向了我的应用程序，并遇到了上述错误，这与Babel-Jest有关。这不在我的软件包中。
构建在本地效果很好，我已经通过删除node_modules和package-lock.json来确认，所有这些都可以安装和运行。
当我推动掌握掌握时，NetLify记录了此错误，而不会继续进行。
因此，我修复了它的方法是在package-lock.json中搜索babel-jest。然后，我将该版本添加到package.json中的分辨率条目中，如下所示：
"resolutions": {
"babel-jest": "23.6.0"
}
这解决了问题，我的应用程序正确地发布了NetLify。
我知道这个问题有点旧，答案已经被选中，但是上述答案对我不起作用。因此，在这里我如何解决问题
将软件包 - 洛克.json放入.gitignore文件中，但是如果您已经将其上传到GitHub而不提到.gitignore文件，则将其从git Cache(local Repo(
中删除git rm -r --cached package-lock.json
git add .
git commit -m 'Remove package-lock.json'
git push origin master
在您的NetLify站点goto网站设置 - ＆gt; build＆amp;部署环境，并将以下内容放入环境变量
SKIP_PREFLIGHT_CHECK=true
并将以下内容放置以构建设置 - ＆gt;如果您的NetLify build假定警告为错误
CI=false npm run build
