根因分析
venv 以 `--without-pip` 创建，或 ensurepip 静默失败，导致环境未安装 pip。
English
A venv was created with `--without-pip`, or ensurepip failed silently, leaving the environment without pip installed.
解决方案
-
90% 成功率
Bootstrap pip via get-pip.py: `curl -sS https://bootstrap.pypa.io/get-pip.py | python`.
-
95% 成功率
Recreate the venv without --without-pip: `rm -rf .venv && python -m venv .venv`.
无效尝试
常见但无效的做法:
-
60% 失败
On some distros (Debian/Ubuntu) ensurepip is disabled and prints a message suggesting apt install python3-pip instead.
-
95% 失败
pip is the module being invoked; the command cannot run before pip exists.
