Question

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

我尝试了一些在网络上找到的解决方案，例如安装此解决方案：

npm i windows-build-tools

但这对我不起作用。

我安装了VS2017，还安装了Platform Toolset v141（最后一个复选框）：VS17 Updater

Answer 1

您可以尝试以这种方式安装Windows-build-tools

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

Answer 2

打开一个cmd.exe，然后查看路径上的MSBuild版本。如果有一个版本，并且它是较旧的版本（例如我的情况），请将其从路径中删除-至少在npm安装期间-并重试。
