如何在 Windows 10 上安裝 web3@1.0.-beta.26？

如何在 Windows 10 上安裝 web3@1.0.-beta.26？npm install --save web3@1.0.0-beta.26不起作用並創建錯誤頁面。

我也試過 –python=python2.7

這是我得到的。

以管理員身份打開命令提示符。

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

您缺少一些建構工具。嘗試安裝上面的包，它將獲取必要的工具和 python 版本。

---

如果上述方法仍然不起作用，請嘗試通過刪除現有的建構工具重新開始

C:\Users'yourUserName’\AppData\Roaming\npm\node_modules\windows-build-tools

打開cmd：（管理員模式）

執行 npm –add-python-to-path=‘true’ –debug install –global –production windows-build-tools

通過執行確保 npm 指向正確的 Python 版本

npm config set python python\path\to\executable

“路徑”應直接指向 Python.exe

**注意：**使用 npm 安裝 windows-build-tools 時，可以找到 python 執行檔

C:\Users'yourUserName’.windows-build-tools\python27

---

我認為以上將解決問題，您可以執行npm install --save web3@1.0.0-beta.26

嘗試更新您的 Node 版本，然後安裝 web3。有同樣的問題，也嘗試過其他事情（使用 VS2015 並安裝 windows-build-tools 並設置 python），但唯一幫助我的是將節點升級到更新版本。
