문제 상황:

• "표준 TCP/IP 포트에 대한 마법사 페이지를 로드할 수 없습니다"라는 오류 메시지가 나타남
• 프린터 속성에서 포트 정보가 보이지 않음
• 레지스트리 편집기에서 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors 경로에 Standard TCP/IP Port 항목이 없음

이러한 문제는 레지스트리 값의 손상으로 인해 발생할 수 있습니다. 이를 해결하기 위해 다음 단계를 수행하십시오:

1. 정상적인 레지스트리 값 백업:
   • 문제가 없는 다른 Windows 7 컴퓨터에서 레지스트리 값을 백업합니다.
   • [윈도우 로고 키 + R]을 눌러 regedit를 입력하고 확인을 클릭하여 레지스트리 편집기를 엽니다.
   • 다음 경로로 이동합니다:

   • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors

   • Monitors 항목을 마우스 오른쪽 버튼으로 클릭하고 "내보내기"를 선택합니다.
   • 파일 이름을 Port.reg로 지정하고 바탕화면에 저장합니다.
2. 백업한 레지스트리 값 병합:
   • 문제가 발생하는 PC로 Port.reg 파일을 복사합니다.
   • Port.reg 파일을 더블 클릭하여 레지스트리에 병합합니다.
   • PC를 재시작합니다.

이 과정을 완료한 후 문제가 해결되었는지 확인하십시오.

  curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
      https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

Configure Plugins

After installing vim-plug, configure your plugins by editing the appropriate configuration file.

• For NVim:

  nvim ~/.config/nvim/init.vim

• For Vim:

  vim ~/.vimrc

In the configuration file, add the following lines to initialize vim-plug and specify your desired plugins:

" in init.nvim or .vimrc
call plug#begin('~/.vim/plugged')

" List your plugins here
Plug 'tpope/vim-sensible'
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }

call plug#end()

Install Plugins

After saving the configuration file, install the specified plugins:

1. Open NVim or Vim.
2. Run the command:

   :PlugInstall

   This command will download and install all the plugins listed in your configuration file.

Managing Plugins with vim-plug

After installing vim-plug, you can manage your plugins using the following commands:

• :PlugInstall to install the plugins
• :PlugUpdate to install or update the plugins
• :PlugDiff to review the changes from the last update
• :PlugClean to remove plugins no longer in the list

In WSL or WSL2 on Windows, the plugged folder is located at ~/.local/share/nvim/plugged

sudo apt update
sudo apt install git make clang libtool-bin libxt-dev libpython3-dev valgrind -y

vim 의존성 환경 설정 (from https://mebadong.tistory.com/92)

sudo cp /etc/apt/sources.list /etc/apt/sources.list~
sudo sed -Ei 's/^# deb-src /deb-src /' /etc/apt/sources.list
sudo apt-get update
sudo apt-get build-dep vim

vim source 복사

git clone https://github.com/vim/vim.git
cd vim/src

vim 이전 설치 대비 설치 환경 초기화

sudo make distclean

vim 설치 config 설정 (python 환경 포함)

./configure --with-features=huge \
            --enable-multibyte \
            --enable-python3interp=yes \
            --with-python3-config-dir=$(python3-config --configdir) \
            --prefix=/usr/local

vim 설치

sudo make
sudo make install

필요한 경우, (vim 과 vi 모두 동작하게, 두 개의 명령어 연동)

sudo ln -s /usr/local/bin/vim /usr/local/bin/vi

Content : "remote: Support for password authentication was removed on" Solution

발생 상황 유추 : Github 로그인 (Password 대신 필요한 경우)

1. GitHub에서 개인 액세스 토큰(Personal Access Token, PAT) 생성:
2. GitHub 계정 설정으로 이동
3. "Developer settings" 클릭
4. "Personal access tokens" 선택 후 "Generate new token" 클릭
5. 토큰에 적절한 권한 부여 (최소한 'repo' 권한 필요)

6. Token generate를 여러 번하지 않기 위해서는 안전한 곳에 저장 필요

7. CLI에 Token 복사 붙여넣기
