运行 npx create-react-app 后发现中等严重性漏洞

问题描述 投票：0回答：4

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

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，如果我尝试在终端上运行 npx create-react-app ，我会收到 82 个 browserslist 和 postcss 依赖项的中等严重性漏洞，显示 正则表达式拒绝服务 我也尝试过使用旧版本的节点，但是漏洞仍然相同。

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。

请建议我对此进行永久修复。

我还使用 npm 审核来包含漏洞

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
并在根目录添加 
"resolutions"
部分。在本节中，您可以尝试指定问题包的版本更新。因此，对于您的 
postcss
来说，它将如下所示（将版本更改为 
npm audit
建议修复的版本）：

  "resolutions": {
    "postcss": "7.0.36",
    "glob-parent": "^5.1.2",
    "css-what": "^5.0.1",
    "normalize-url": "^4.5.1"
  }

上面的配置似乎是我解决我的 CRA 项目的方式，该项目报告了 8 个漏洞，其中 4 个中度漏洞和 4 个高漏洞，直至 1 个中度漏洞（涉及 

browserslist
包）。 
postcss
的 7.0.36 版本是最新版本 7 
postcss
，已从 
postcss
版本 8 向后移植了 ReDoS 修复。我尝试在分辨率中将 
postcss
更新为 8，但它会导致其他问题，我猜测，与 WebPack 中使用的 
postcss
插件的重大更改有关。我是一名网络开发新手，所以我在这里猜测。最后，我似乎无法更新 
browserlist
，而不会在执行 
npm start
时导致运行时出现“浏览器列表模块未找到”错误。

这是我的终端输出，一切就绪并正在运行

我多次遇到这个恼人的错误，这就是我修复错误的方法，

第一次运行

npm audit

然后大多数时候它会问我：npm ERR！审核 尝试先使用以下命令创建一个： npm i --package-lock-only

然后我输入

npm i --package-lock-only

大多数情况下它都有效，不会再出现漏洞。

发生错误，但我不知道真正原因是什么。 我提供的解决方案对我有用，并且没有更多漏洞。

暂时（希望）解决此问题的一个粗略方法是将其添加到依赖项和分辨率中。

将其添加到分辨率中将完全停止安装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的版本。

然后它会找到并使用已安装的依赖项（更新版本）作为构建时react-scripts的依赖项。

    "browserslist": "^4.16.5",

Postcss 的降级只是由 4 个漏洞 76 造成的... 我什至降级了所有其他使用 postcss 的依赖项。 徒劳地看起来比以前更严重了。我重做了所有...
