source venv/bin/activate 后 which python 还是系统 Python,或 deactivate 报错。
- 当前 shell 是 fish/zsh 但用了 bash 语法(
sourcevs.) - 在 venv 外又创建了 venv(路径嵌套)
.bashrc中有硬编码路径覆盖了 PATH
# Python venv 激活失败或路径不匹配
echo $SHELL
# 2. 正确的激活方式
# bash/zsh:
source venv/bin/activate
# 或:
. venv/bin/activate
# fish:
source venv/bin/activate.fish
# 3. 验证
which python # 应指向 venv/bin/python
python -c "import sys; print(sys.prefix)" # 应显示 venv 路径
# 4. 重建 venv(如果目录损坏)
rm -rf venv
python3 -m venv venv
source venv/bin/activate
pip install --upgrade pip setuptools wheel- Follow the solution steps in order
- Run any relevant commands or tests to confirm the fix
- Verify the symptom no longer occurs
- Check related logs or outputs for expected behavior
- 永远不要在 venv 已激活时运行
python3 -m venv venv— 这会创建嵌套 venv - 把
source ~/venv/bin/activate写在 .bashrc 里会导致脚本 curl 等工具找不到 venv 包
