满足要求PyDispatcher-2.0.5 (来自版本:无)

Question

Python 3.9.5来了：

deactivate
rm -rf venv/
python -m venv venv
source venv/bin/activate
python -V
python -m pip install --upgrade pip
python -m pip install wheel

很好。

看看development.txt：

mariadb==1.0.5
python-binance==1.0.10
python-decouple==3.3
PyMySQL==0.10.1
mplfinance==0.12.7a4
newtulipy==0.4.6
autobahn==21.3.1
PyQt6==6.1.1
pyqtgraph==0.12.1
PyOpenGL==3.1.5
PyDispatcher-2.0.5
shortuuid==1.0.1

试试这个: development.txt (has is PyDispatcher==2.0.5)。为你自己试试这个：

python -m pip install -r requirements/development.txt
ERROR: Could not find a version that satisfies the requirement PyDispatcher-2.0.5 (from versions: none)
ERROR: No matching distribution found for PyDispatcher-2.0.5

为什么？

而是靠他自己：

pip install PyDispatcher
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: PyDispatcher in /home/jonsl/.local/lib/python3.9/site-packages (2.0.5)

很好。

为什么？

谢谢大家。

Answer 1

事实证明：pyqtgraph==0.12.1

需要使用：PyQt6==6.1.1代替pyqtgraph==0.12.2

此外，除非需要，否则永远不要使用from ... import ...。
