VS Code安装Pylint后Pylance功能失效，求解决方案

排查与修复步骤： #

1. 确认Python语言服务选择 #

VS Code的Python智能提示、语法高亮由语言服务驱动，安装Pylint后可能意外切换了默认服务：

• 打开命令面板（Ctrl+Shift+P），输入Python: Select Language Server
• 选择Pylance作为默认语言服务，重启VS Code验证功能是否恢复

2. 解决环境与配置冲突 #

你的settings.json中配置了"pylint.importStrategy": "fromEnvironment"，可能导致Pylint与Pylance依赖的Python环境不一致：

• 先临时禁用Pylint插件，重启VS Code，若Pylance恢复，则说明两者存在环境冲突
• 若确认冲突，可修改Pylint的导入策略：将"pylint.importStrategy": "fromEnvironment"改为"pylint.importStrategy": "useBundled"，使用插件自带的Pylint版本，避免环境干扰
• 或者统一两者的Python解释器：打开命令面板输入Python: Select Interpreter，选择同一个Python环境，再重新启用Pylint

3. 重置Pylance配置 #

配置缓存异常也可能导致功能失效：

• 打开VS Code设置（Ctrl+,），搜索python.analysis.resetSettings，点击重置按钮
• 或者直接在settings.json中检查是否存在"python.languageServer": "Jedi"或"None"，若有则修改为"python.languageServer": "Pylance"

你的settings.json配置： #

{
    "terminal.integrated.defaultProfile.windows": "Git Bash",
    "[python]": {
        "editor.formatOnType": true
    },
    "workbench.iconTheme": "material-icon-theme",
    "explorer.confirmDragAndDrop": false,
    "explorer.confirmDelete": false,
    "git.confirmSync": false,
    "gitlens.gitCommands.skipConfirmations": [
        "fetch:command",
        "stash-push:command",
        "switch:command",
        "remote-add:command"
    ],
    "vscode-office.previewCodeHighlight.style": "github",
    "workbench.statusBar.visible": false,
    "editor.unicodeHighlight.invisibleCharacters": false,
    "editor.unicodeHighlight.ambiguousCharacters": false,
    "workbench.colorTheme": "Default Dark+",
    "python.analysis.autoImportCompletions": true,
    "pylint.importStrategy": "fromEnvironment",
    "python.autoComplete.extraPaths": [

    ],
    "python.analysis.extraPaths": [],
    "editor.fontLigatures": false
}
