【问题描述】:
晚上好,
我正在使用 python 3.9 并尝试根据 Internet https://www.uvicorn.org/ 上的文档在 Windows 10 Pro 上运行新的 FastAPI 服务,我执行了以下语句
pip install uvicorn pip install uvicorn[standard]
创建示例文件 app.py
from fastapi import FastAPI
app = FastAPI()
@app.get("/")
async def root():
return {"message": "Hello World"}
但是当我运行下面的代码时:
uvicorn main:app --reload
uvicorn : The term 'uvicorn' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify t
hat the path is correct and try again.
At line:1 char:1
+ uvicorn
+ ~~~~~~~
+ CategoryInfo : ObjectNotFound: (uvicorn:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException
我还在环境设置中添加了Python的路径
我还重新安装了 Python 3.9,并将默认安装路径设置为 c:\ProgramFiles\Python39,此路径现在也包含在系统环境和用户环境设置中。
如果我再次运行 pip install uvicorn 它会显示以下语句:
λ pip install uvicorn
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: uvicorn in c:\users\username\appdata\roaming\python\python39\site-packages (0.12.2)
Requirement already satisfied: h11>=0.8 in c:\users\username\appdata\roaming\python\python39\site-packages (from uvicorn) (0.11.0)
Requirement already satisfied: click==7.* in c:\users\username\appdata\roaming\python\python39\site-packages (from uvicorn) (7.1.2)
WARNING: You are using pip version 20.2.3; however, version 20.2.4 is available.
You should consider upgrading via the 'c:\program files\python39\python.exe -m pip install --upgrade pip' command.
非常感谢
埃里克

尝试将
\pip添加到该路径的末尾。 -
@John:我照你说的做了!但它还没有解决问题!查看调整后的问题

嗯。试试
%APPDATA%\Python? -
@John 感谢您的快速回复。它仍然无法正常工作。我又改了问题

你试过用
pip3 install ...安装它吗?
