proxy認証(@含)でのpip

Qiitaの記載記事も、ネットの記事もうまくいかない場合ためしてみてください。
Windowsの場合、環境変数に登録すれば問題は解決しますが、ここでは別の手法を提案します。

pipでエラー

bat

(venv) $ pip install request
Collecting request
  Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('
<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x000001BF9A115668>: Failed to establish a new connection: [Errno 11001] getaddrinfo failed',)': /simple/request/

pip --proxyでエラー

bat

(venv) $ pip install request
Collecting request
  Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('
<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x000001BF9A115668>: Failed to establish a new connection: [Errno 11001] getaddrinfo failed',)': /simple/request/

set proxy

ここらへんを参考に

bat

(venv) $ set set HTTP_PROXY=http://[username]%40[userdomain]:[password]@[proxy]:[port]
(venv) $ set set HTTPS_PROXY=http://[username]%40[userdomain]:[password]@[proxy]:[port]
(venv) $ pip install request
Collecting request
  Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('
<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x000001BF9A115668>: Failed to establish a new connection: [Errno 11001] getaddrinfo failed',)': /simple/request/

結論

環境変数に登録する
- HTTP_PROXY=http://[username]%40[userdomain]:[password]@[proxy]:[port]
もしくは！set コマンドを使う
- ただし「%%40」にする
  - set HTTP_PROXY=http://[username]%%40[userdomain]:[password]@[proxy]:[port]

bat

set HTTP_PROXY=http://[username]%%40[userdomain]:[password]@[proxy]:[port]
set HTTP_PROXY=http://[username]%%40[userdomain]:[password]@[proxy]:[port]
pip install request

pipをバッチにしておく

ppipというバッチを作り、Proxyを気にしないpipを準備します。
ppipはPATHに通してください

ppip.bat

@echo off

if "%1" equ "install" (
  goto proxy_install
)
if "%1" equ "show" (
  goto show
)

:show
pip freeze
goto end


:proxy_install
rem batの場合%%40
set HTTP_PROXY=http://[username]%%40[userdomain]:[password]@[proxy]:[port]
set HTTP_PROXY=http://[username]%%40[userdomain]:[password]@[proxy]:[port]
pip install %2
goto end


:end

python

ppip install request
