无效尝试

常见但无效的做法:

  1. Installing starlette with pip but using a virtual environment not activated. 80% 失败

    If the virtual environment is not activated, the package is installed in the system Python, not the project's environment.

  2. Assuming starlette is included with FastAPI. 60% 失败

    FastAPI depends on Starlette, but if you install only FastAPI, Starlette is installed as a dependency. However, if you uninstall FastAPI, Starlette may also be removed.
