請在此處查看我之前的問題。我整天都在尋找我的問題是什么，但仍然遇到 pip install 問題。這次我的錯誤資訊有點不同。自上一篇文章以來我做了什么：
- 確保
C:\mysys64\mingw64\bin已在系統環境變數下添加到我的路徑中 - 將VSCode 中的
c_cpp_properties.json具體編輯為"intelliSenseMode""windows-msvc-x64""windows-gcc-x64" - 重新檢查我的 Python.h 目錄下的檔案
C:\msys64\mingw64\include\python3.9\Python.h，以確保錯誤已經消失#include <unistd.h>。 - 重試
pip install Flask-SQLAlchemy，現在我收到以下錯誤...

#include <unistd.h>但是，在我的 Python.h 檔案中不再有彎曲的錯誤行。請注意，我不知道我在做什么來解決這個問題。請讓我知道是否有解決方案。
uj5u.com熱心網友回復：
您可以簡單地從這里下載適當的 whl 檔案并安裝它。
因為你greenlet?1.1.2?cp39?cp39?win_amd64.whl應該是正確的。下載后，cd到你的下載目錄并運行
C:\msys64\mingw64\bin\python.exe -m pip install greenlet?1.1.2?cp39?cp39?win_amd64.whl
然后再次嘗試您的原始安裝。
筆記
Flask_SQLAlchemy?2.5.1?py3?none?any.whl在同一網站上還有一個 whl 檔案可用。您也可以下載并安裝它
uj5u.com熱心網友回復：
中的點與 中的py -m pip點不同pip list。您可以通過py -m pip --version并pip --version獲取點子位置。
我可以通過以下方式成功安裝greenlet包：
pip install greenlet --no-cache-dir
我正在使用python310，看起來python39有一些問題。如果它不起作用，正如@FlyingTeller 建議的那樣，您可以手動下載它。
正如你所描述greenlet-1.1.2-cp39-cp39-win_amd64.whl的不起作用，所以你試過了greenlet?1.1.2?cp39?cp39?win32.whl嗎？
>>> import platform
>>> platform.architecture()
您可以通過上述代碼獲得架構。
