Tensorflow Nodegyp即使已安装，也无法生成

Question

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一些问题。每当我npm install @tensorflow/tfjs-node 时，我都会遇到以下错误：

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

所以我仔细查看了错误，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，我会得到一个404（或一个未找到的页面）

那么可能是这样？我如何找到那个文件

Answer 1

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

基于this issue，您的先决条件安装似乎存在一些问题。因此，以下链接可能有助于您解决问题：

install node-gyp on windows

Error installing node-gpu（本期是关于gpu的，但主要问题与您的问题相同）

Answer 2

我也有同样的问题，当我使用python 3而不是python 2时，它对我很有效。 尝试安装Python3.8.3

Answer 3

您必须安装Python3，TensorFlow不会构建您拥有的python版本。 https://www.tensorflow.org/install
