无法在公司代理后面安装tfjs节点

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。

出现问题的原因是tensorflowtfjs-nodescriptsinstall.js不支持代理，因此它尝试直接从服务器获取https://storage.googleapis.com/tensorflow/libtensorflow/libtensorflow-cpu-windows-x86_64-1.15.0.zip，但这是不可能的。">

我已经设置了我的npm配置

$npm config list

console.log为：

; cli configs
metrics-registry = "http://registry.npmjs.org/"
scope = ""
user-agent = "npm/6.14.4 node/v12.18.0 win32 x64"
; userconfig C:Usersuser.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 Filesnodejsnode.exe
; cwd = C:IPAbeautyTrackingServerProject
; HOME = C:Usersusename
; "npm config ls -l" to show all defaults.

正如你所看到的，由于代理，我得到了下一个错误。

$ npm install @tensorflow/tfjs-node
> @tensorflow/tfjs-node@2.0.1 install C:IPAbeautyTrackingServerProjectnode_modules@te
> node scripts/install.js

我想我可能需要更改tensorflowtfjs-nodescriptsinstall.js以添加代理？

请帮忙！

3天后，我设法让它工作起来。问题在代理的定义中

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

线40&41

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

当以1(或2(方式定义代理时，它不会检测到process.env

1. npm config edit
2. .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CMDHTTP_PROXY=http://182.192.254.44:8080/

所以它将工作

只需键入：npm install @tensorflow/tfjs-node即可享受！
