pip로 Aider 설치하기: API 키 설정과 Git 저장소 터미널 페어 프로그래밍

aider-chat pip 설치, API 키, Git에서 aider 실행, 검토 가능한 변경 하나.

The first hour with terminal pair programming in a Git repo usually breaks on the wrong PyPI package, missing OPENAI_API_KEY or ANTHROPIC_API_KEY, or running outside a Git work tree—not on the prompt. Install with pip install aider-chat, export keys, run aider at the repo root, then land one change you can read in git diff.

검색어는 pip로 Aider를 설치해 터미널에서 페어 프로그래밍하는 방법. This page follows Aider docs at aider.chat for install, LLM setup, and Git integration. Aider is a separate open-source terminal tool, not this site’s meeting product. To walk a diff on a short call, open a room on wbmeet; see how to create and join a room.

What Aider does in the terminal

Aider is a Git-aware terminal pair programmer: you describe tasks in natural language, the model edits project files, and changes can be tracked with Git. The PyPI package is aider-chat; the CLI is usually aider. It supports OpenAI, Anthropic, and other providers via environment variables or a gitignored .env—never commit keys. You need Python 3.8+, git, and a initialized or cloned repository in the directory you start from.

Install Aider with pip

1. 1

   Python and Git

   Check python3 --version (3.8+) and git --version. Use a virtualenv (python3 -m venv .venv, then activate) so the install does not touch system Python.

2. 2

   Install aider-chat

   Run python -m pip install -U aider-chat. Verify with aider --version. If the command is missing, activate the venv or check pip show aider-chat for the scripts path.

3. 3

   Optional pin

   Teams may pin versions in requirements-dev.txt without putting secrets there. Upgrade with pip install -U aider-chat and read release notes.

Configure OpenAI or Anthropic keys

1. 1

   Create keys in the vendor console

   OpenAI: platform.openai.com. Anthropic: console.anthropic.com. Billing and regions follow each vendor. Do not paste live keys into tickets or Git.

2. 2

   Export environment variables

   export OPENAI_API_KEY=… or export ANTHROPIC_API_KEY=…. Aider also supports a repo-root .env that must stay gitignored. Pick one provider and pass --model with a supported model id.

3. 3

   Pick a model id

   Start with a model listed in current Aider docs (e.g. a GPT-4o class or Claude Sonnet id). Wrong names yield 404/401—smoke-test with a read-only question first.

Pair-program in your Git repo

1. 1

   cd to the repo root

   Work inside a directory with .git. Run git status so you know what changed before and after Aider edits.

2. 2

   Launch aider

   Run aider or aider --model MODEL. Scope context with aider path/to/file.py on large trees. Ask for explanations first, then a small test or fix with “show the diff first.”

3. 3

   Review diff before commit

   Read git diff line by line. Auto-commit behavior depends on flags and version; hour one: commit manually with your own message so git revert stays easy.

Comparison and pitfalls

Official path: pip install aider-chat → set OPENAI/ANTHROPIC keys → aider in a Git repo → review git diff. Trust aider.chat for details.

Vs Claude Code / Copilot CLI

Different install and auth paths. See our Claude Code and Copilot CLI notes.

OpenAI required?

No—Anthropic and other supported providers work; see Aider’s LLM list.

Not a meeting-product guide

Only Aider’s first hour. Short call: wbmeet.
