在ubuntu 18.04上安装mu编辑器时出错

Question

我不能在ubuntu上安装mu编辑器。下面我会照搬上面写的。我尝试了很多事情，也许我把一切都搞砸了

ERROR: Cannot install mu-editor==1.0.0, mu-editor==1.0.1, mu-editor==1.0.2 and mu-editor==1.0.3 because these package versions have conflicting dependencies.

The conflict is caused by:
    mu-editor 1.0.3 depends on qscintilla==2.11.4
    mu-editor 1.0.2 depends on PyQtChart==5.11.3
    mu-editor 1.0.1 depends on qscintilla==2.10.7
    mu-editor 1.0.0 depends on qscintilla==2.10.7

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

Answer 1

您有库版本冲突。

在我的18.04LTS系统中，所有来自官方存储库的包( Python3 3@3.6.9，pip3 3@9.0.1)都是我通过使用以下命令调整mu-editor包版本来正常安装Python3的：

pip3 install --user qscintilla==2.10 PyQtChart==5.9.2 pyqt5==5.9.2 mu-editor==1.0.3

如果使用相同的python3版本，但使用升级的pip3 3@21.1.2，则可以使用下面的安装命令：

pip3 install --user qscintilla==2.11.4 mu-editor==1.0.3

请注意，mu-editor deb-包只在20.04 LTS之后才在正式的Ubuntu存储库中显示。
