"tfjs_binding.node"在已安装的文件夹中找不到@tensorflow

Question

当我尝试使用张量流的某些功能时，它稍后会给出错误，因为"tfjs_binding.node"@tensorflow在insatlled文件夹中找不到。

我已经安装了Python 2.7，因为它必须在张量流之前作为要求安装。 并通过"python -v"检查其有效性

所以下面是当我尝试安装 @tensorflow/tfjs-node 时。 请帮我清理一些事情...

我在Windows 10上@tensorflow\tfjs节点版本@1.5.2和@1.7.4有同样的问题。节点版本 @12.18.3 LTS

当我们尝试更新和安装软件包并且某些依赖项未正确安装时，会发生这种情况。 尝试npm uninstall @tensorflowtfjs-node是否正在使用 npm。然后使用npm i @tensorflowtfjs-node安装最新版本的张量流，它将起作用。或者，如果您只希望特定版本的 tensorflow 在您的项目中运行，请尝试遵循下面评论中给出的方法(在我的情况下是@1.5.2(。

1. 首先，在检查 python 版本时，我必须将 python v2 设置为默认 python。

2. 我不得不以管理员身份打开Windows Power shell并输入上面显示的命令。

   npm install -g windows-build-tools
   

   花了几分钟，就完成了。

3. 我也安装了@tensorflow/tfjs，之后@tensorflow/tfjs-node"在我的项目中。

这就是我解决我的问题的方式。

旁注 => Windows 上的某些节点版本存在张量流问题，例如我必须从 v10.16.0 升级到 v10.15.3。
