如何正确挂代理解决执行 npm install 出现连接错误的问题？

我参考教程 https://www.electronjs.org/docs/tutorial/first-app

mkdir, cd, npm init都没有问题

~/.bashrc 内容：

export HTTP_PROXY=http://127.0.0.1:8123/
export HTTPS_PROXY=http://127.0.0.1:8123/
export http_proxy=http://127.0.0.1:8123/
export https_proxy=http://127.0.0.1:8123/

~/.npmrc 内容：

proxy=http://127.0.0.1:8123/
http-proxy=http://127.0.0.1:8123/
https-proxy=http://127.0.0.1:8123/
noproxy=localhost,127.0.0.1,192.168.,10.
strict-ssl=false

执行npm install --save-dev electron时出现连接错误如下：

lala@ubu:~/projects/electron/my-app 17:20:34
$ npm install --save-dev electron

家里的河南联通不能直接访问 github.com(13.250.177.223)。但是代理已经配置成上边那样子了，没效果。

查了一圈 Google 和 stackoverflow 没找到，上 stackoverflow 提问目前为止还没人理我（请不要笑我的烂英语：）

https://stackoverflow.com/questions/60054531/how-can-i-solve-the-connection-problem-during-npm-install-behind-a-proxy

请问各位如何才能解决这个连接问题呢？

@learnshare 还是不行，错误一样

```
lala@ubu:~/projects/electron/my-app 09:20:18
$ ALL_PROXY=http://127.0.0.1:8123 npm install --save-dev electron

@learnshare 多谢你的建议！

现在我的 bashrc 和 npmrc 如下

lala@ubu:~/projects/electron/my-app 09:49:34
$ cat ~/.npmrc
proxy=http://127.0.0.1:8123/
http-proxy=http://127.0.0.1:8123/
https-proxy=http://127.0.0.1:8123/
noproxy=localhost,127.0.0.1,192.168.,10.
strict-ssl=false
global.GLOBAL_AGENT=true
global.GLOBAL_AGENT.HTTP_PROXY=http://127.0.0.1:8123/
global.GLOBAL_AGENT.HTTPS_PROXY=http://127.0.0.1:8123/
lala@ubu:~/projects/electron/my-app 09:49:41
$ tail -n 10 ~/.bashrc

export ANDROID_HOME=/home/lala/AndroidSDK
export HTTP_PROXY=http://127.0.0.1:8123/
export HTTPS_PROXY=http://127.0.0.1:8123/
export http_proxy=http://127.0.0.1:8123/
export https_proxy=http://127.0.0.1:8123/
export GLOBAL_AGENT_HTTP_PROXY=http://127.0.0.1:8123/
export GLOBAL_AGENT_HTTPS_PROXY=http://127.0.0.1:8123/
export ELECTRON_GET_USE_PROXY=true
export ELECTRON_MIRROR="https://cdn.npm.taobao.org/dist/electron/"

但是还是卡在这个地方。但是另一方面这个 electron 依赖看起来已经下载下来了
lala@ubu:~/projects/electron/my-app/node_modules/electron 09:50:52
$ tree .
.
├── cli.js
├── electron.d.ts
├── index.js
├── install.js
├── LICENSE
├── package.json
└── README.md

0 directories, 7 files
lala@ubu:~/projects/electron/my-app/node_modules/electron 09:51:10
$ wc electron.d.ts
13622 61347 541692 electron.d.ts

所以要解决的这个问题应该不是下载依赖，而是如何解决连接问题。

@learnshare 现在指示删掉了 bashrc 里的那些，npmrc 里边还剩如下：
lala@ubu:~/projects/electron/my-app 10:13:56
$ cat ~/.npmrc
noproxy=localhost,127.0.0.1,192.168.,10.
strict-ssl=false
global.GLOBAL_AGENT=true
global.GLOBAL_AGENT.HTTP_PROXY=http://127.0.0.1:8123/
global.GLOBAL_AGENT.HTTPS_PROXY=http://127.0.0.1:8123/
registry=https://registry.npm.taobao.org

执行 ALL_PROXY=http://127.0.0.1:8123 npm install --loglevel silly 的时候没有任何问题，一切正常。

但是执行 ALL_PROXY=http://127.0.0.1:8123 npm install --loglevel silly --save-dev electron 还是报那个错，最终结果显示出来还是安装完成，中间日志如下：

我再等一会再看看
