Web3js
windows10如何手動安裝web3最新版本？
我使用npm install web3將安裝（截至目前）v1.0.0-beta.41
但它給了我以下錯誤：

我可以安裝 web3@0.20.7，但我想要最新版本，因為 0.20.7 中的一些功能已在 v1.0.0 中刪除/重新排列我所需要的是當我需要時 nodejs 不應該抱怨（‘web3’） .
我想知道如何安裝帶有依賴項的 web3 包。還有如何告訴 E:\node_modules\scrypt\build\scrypt_wrapper.vcxproj（我檢查時 node_modules 內沒有scrypt文件夾）使用 V140 或任何已安裝的 platformSetTools。
我在C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0中有以下文件夾
- V120
- V140
是否可以將安裝在其他人系統上的 web3（帶有依賴項）合併到我的系統中？
更新： 我在目前電腦上安裝了以下軟體：
- 視覺工作室 2015
- Microsoft .NET Framework（4.5 多目標包 (MTP)、4.5 sdk、4.5.1 MTP、4.5.1 MTP (ENU)、4.5.1 SDK、4.5.2 SDK、4.5.2 MTP、4.5.2 MTP ENU、 4.6 SDK, 4.6 目標包, 4.6 TP ENU, 4.6.1 SDK, 4.6.1 TP, 4.6.1 TP ENU, 4.7 SDK, 4.7 TP, 4.7 TP ENU)
- 微軟 Visual C++ (2008,2012,2013,2017)
我也可以在 Windows 7（也有 Visual Studio 2015）中*npm install web3並且它執行/安裝沒有錯誤。*這是嘗試安裝 windows-build-tools 和 web3 包後的輸出。

不確定（因為您沒有提供完整的錯誤日誌），但我認為問題出在 some
build-tools上，安裝它會解決您的問題。npm install -g windows-build-tools**注意：**確保
windows-build-tools全域安裝。
- 解除安裝/重新安裝節點（也刪除了本地目錄中的所有相關文件夾，包括漫遊）
- 在 POWERSHELL 中作為管理員：
npm install --global --production windows-build-toolsnpm install --save --no-optional web3.希望這對你有用。
