Tensorflow - 即使安装了 Nodegyp 也无法构建
Tensorflow - Nodegyp failed to build even if it is installed
我正在尝试为演示应用程序设置 TensorFlow 但是我在构建它时遇到了一些问题 我每次 npm install @tensorflow/tfjs-node :
都会收到以下错误

节点版本：12.13.0
我的操作系统是Windows
Python --版本：
Python 2.7.18
谁能告诉我我做错了什么？
更新
所以我查看了错误并发现了一个小细节：
这一行：
node-pre-gyp WARN Tried to download(404): https://storage.googleapis.com/tf-builds/pre-built-binary/napi-v5/2.8.1/CPU-windows-2.8.1.zip
如果我转到那个 URL 我会正确地得到 404（或未找到的页面）
所以可能是这样？如何找到该文件？
您必须安装 python 3，使用 python 版本的 TensorFlow 将无法构建。
https://www.tensorflow.org/install
我遇到了同样的问题，当我使用 python 3 而不是 python 2 时，它对我有用。
尝试安装 Python 3.8.3
根据错误：
node-pre-gyp WARN Tried to download(404): https://storage.googleapis.com/tf-builds/pre-built-binary/napi-v5/2.8.1/CPU-windows-2.8.1.zip
并且根据 this issue，看来您的先决条件安装可能存在一些问题。所以可能以下链接可以帮助您解决问题：
Error installing node-gpu(这个问题是关于gpu的，但主要问题和你的问题一样)
考虑到我的不同设置（我在 macOS Catalina 上）的价值，干净项目上的 npm install @tensorflow/tfjs-node 导致 node-pre-gyp install failed with error: Error: Command failed: node-pre-gyp install --fallback-to-build ，因为工作文件夹的父级之一有名称中的空格。显然这在 2021 年仍然会发生。
转向更传统的路径解决了问题。
