完成后sudo apt update
,我开始输入sudo apt install pyqt
,然后按两次 tab 键以查看可用的包:
pyqi pyqt5chart-dev pyqt5.qsci-dev pyqwt3d
pyqso pyqt5-dev pyqt5webengine
pyqt5 pyqt5-dev-tools pyqt-qwt
pyqt5chart pyqt5-examples pyquery
然后,当我尝试使用 安装时sudo apt install pyqt5
,它说E: Unable to locate package pyqt5
. 为什么要在我按两次 Tab 键时列出它?
