Question

我制作了一个用于对象检测的tfjs解决方案，并希望将其部署在公司代理后面的服务器上。

发生问题是因为tensorflow\tfjs-node\scripts\install.js不支持代理，因此它试图直接从服务器获取https://storage.googleapis.com/tensorflow/libtensorflow/libtensorflow-cpu-windows-x86_64-1.15.0.zip，而这是不可能的。'

我已经设置了我的npm配置

$npm config list

和console.log是：

; cli configs
metrics-registry = "http://registry.npmjs.org/"
scope = ""
user-agent = "npm/6.14.4 node/v12.18.0 win32 x64"
; userconfig C:\Users\user\.npmrc
https-proxy = "http://182.192.254.44:8080/"
proxy = "http://182.192.254.44:8080/"
python = "="
registry = "http://registry.npmjs.org/"
strict-ssl = false
; builtin config undefined
prefix = "C:\\Users\\user\\AppData\\Roaming\\npm"
; node bin location = C:\Program Files\nodejs\node.exe
; cwd = C:\IPA\beauty\TrackingServerProject
; HOME = C:\Users\usename
; "npm config ls -l" to show all defaults.

如您所见，由于代理服务器，我遇到下一个错误。

$ npm install @tensorflow/tfjs-node
> @tensorflow/tfjs-node@2.0.1 install C:\IPA\beauty\TrackingServerProject\node_modules\@te
> node scripts/install.js
CPU-windows-2.0.1.zip

我认为我可能需要更改tensorflow\tfjs-node\scripts\install.js才能添加代理？

请帮助！

我成功地让它在3天的问题是代理定义后才能正常工作

tensorflow \ tfjs-node \ scripts \ resources.js（https://github.com/tensorflow/tfjs/blob/master/tfjs-node/scripts/resources.js）

第40和41行

const proxy = process.env['HTTPS_PROXY'] || process.env['https_proxy'] ||
      process.env['HTTP_PROXY'] || process.env['http_proxy'] || '';

以方法1）或2）定义代理服务器时，不会检测到process.env

npm config edit
.npmrc

因此，您需要以以下形式传递PowerShell的系统变量： $env:HTTP_PROXY="http://182.192.254.44:8080/"

或对于CMD HTTP_PROXY=http://182.192.254.44:8080/

所以它将起作用

只需输入：npm install @tensorflow/tfjs-node即可享受！

无法在公司代理后面安装tfjs-node
