我正在尝试安装此库Barcode-Scanner-npm，但安装失败并显示此错误：

C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.Cpp.Platform.targets(57,5): error MSB8020: The build t
ools for v141 (Platform Toolset = 'v141') cannot be found. To build using the v141 build tools, please install v141 bui
ld tools.  Alternatively, you may upgrade to the current Visual Studio tools by selecting the Project menu or right-cli
ck the solution, and then selecting "Retarget solution". [C:\Users\bla\Desktop\bla\myProject\node_modules\@serialport\bin

我尝试了一些我在网上找到的解决方案，比如安装这个：

npm i windows-build-tools

但它对我不起作用。

我安装了 VS2017 和 Platform Toolset v141，您可以在此处看到（最后一个复选框）：VS17 Updater

【解决方案1】：

你能试试用这种方式安装windows-build-tools吗

npm install --global --production windows-build-tools

【解决方案2】：

打开cmd.exe 并查看您的路径上的 MSBuild 版本。如果有一个并且它是旧版本（对我来说就是这种情况），请将其从路径中删除 - 至少在你的 npm 安装时 - 然后再试一次。
