运行 npx create-react-app 后发现的中等严重性漏洞
Moderate severity vulnerabilities found after running npx create-react-app
我已经在 Windows 上安装了 32 位的最新 LTS 版本：14.17.0（包括 npm 6.14.13）。
安装节点后，我使用 npm i create-react-app -g
在全局安装了 create-react-app 模块
我已经成功安装了它们，没有任何错误。
但是，如果我尝试 运行 npx create-react-app 在我的终端上，我会得到 browserslist 和 的 82 个中等严重性漏洞postcss 依赖项说 正则表达式拒绝服务
我也尝试过使用旧版本的节点，但漏洞仍然相同。
在脚本中包含 "preinstall": "npx npm-force-resolutions" 并在我的 package.json 文件中包含 "resolutions": "^3.8.0" 后，漏洞得到修复。
但是，我每次创建新项目时都会这样做。
请建议我永久修复此问题。
我还包括使用 npm audit 的漏洞

在 CRA 团队更新 react-scripts 之前，我认为要使 npx npm-force-resolutions 正常工作，您可能需要编辑 package.json 并在根目录中添加 "resolutions" 部分.在本节中，您可以尝试为问题包指定版本更新。因此，对于您的 postcss，它看起来如下所示（将版本更改为 npm audit 建议的修复版本）：
"resolutions": {
"postcss": "7.0.36",
"glob-parent": "^5.1.2",
"css-what": "^5.0.1",
"normalize-url": "^4.5.1"
}
以上配置似乎解决了我的 CRA 项目报告 8 个漏洞，其中 4 个中度漏洞和 4 个高漏洞下降到 1 个中度漏洞关于 browserslist 包。 postcss 的 7.0.36 版是最新版本 7 postcss，它已从 postcss 版本 8 向后移植了 ReDoS 修复程序。我尝试将 postcss 的分辨率更新为 8，但它导致其他问题，我猜这些问题与 WebPack 中使用的 postcss 插件的重大更改有关。我是网络开发新手，所以我在这里猜测。最后，在执行 npm start.
时，如果不在运行时导致 'browserlist module not found' 错误，我似乎无法更新 browserlist
这是我的终端输出，一切就绪 运行 npm i

我多次遇到这个烦人的错误，这就是我修复错误的方法，
第一个运行npm audit
然后大多数时候它会问我：npm ERR！ audit 尝试先创建一个：npm i --package-lock-only
然后我输入 npm i --package-lock-only
而且大多数情况下都有效，不再有漏洞。
发生了错误，但我不知道真正的原因。
我提供的解决方案对我有效，没有更多的漏洞。

这是一张显示我使用的解决方案的图片。
[2]: https://i.stack.imgur.com/DQFUV.jpg
临时（希望）解决此问题的一种粗略方法是将其添加到依赖项和解决方案中。
将其添加到解决方案将完全停止安装 react-scripts 的依赖项（故意导致模块未找到错误）。
将其添加到依赖项将安装更新版本。
然后它会找到并使用安装的依赖（更新版本）作为反应脚本对构建的依赖。

在 CRA 团队更新 react-scripts 之前，我认为要使 npx npm-force-resolutions 正常工作，您可能需要编辑 package.json 并在根目录中添加 "resolutions" 部分.在本节中，您可以尝试为问题包指定版本更新。因此，对于您的 postcss，它看起来如下所示（将版本更改为 npm audit 建议的修复版本）：
"resolutions": {
"postcss": "7.0.36",
"glob-parent": "^5.1.2",
"css-what": "^5.0.1",
"normalize-url": "^4.5.1"
}
以上配置似乎解决了我的 CRA 项目报告 8 个漏洞，其中 4 个中度漏洞和 4 个高漏洞下降到 1 个中度漏洞关于 browserslist 包。 postcss 的 7.0.36 版是最新版本 7 postcss，它已从 postcss 版本 8 向后移植了 ReDoS 修复程序。我尝试将 postcss 的分辨率更新为 8，但它导致其他问题，我猜这些问题与 WebPack 中使用的 postcss 插件的重大更改有关。我是网络开发新手，所以我在这里猜测。最后，在执行 npm start.
browserlist
这是我的终端输出，一切就绪 运行 npm i

我多次遇到这个烦人的错误，这就是我修复错误的方法，
第一个运行npm audit
然后大多数时候它会问我：npm ERR！ audit 尝试先创建一个：npm i --package-lock-only
然后我输入 npm i --package-lock-only
而且大多数情况下都有效，不再有漏洞。
发生了错误，但我不知道真正的原因。 我提供的解决方案对我有效，没有更多的漏洞。

这是一张显示我使用的解决方案的图片。 [2]: https://i.stack.imgur.com/DQFUV.jpg
临时（希望）解决此问题的一种粗略方法是将其添加到依赖项和解决方案中。
将其添加到解决方案将完全停止安装 react-scripts 的依赖项（故意导致模块未找到错误）。
将其添加到依赖项将安装更新版本。
然后它会找到并使用安装的依赖（更新版本）作为反应脚本对构建的依赖。
