我在 Ubuntu 中为 python3 使用 vscode。 Error-squiggle-lines 已停止为 Python 工作（它适用于其他语言）。我正在使用微软的 Python 扩展。vscode v1.41.1 Ubuntu v18.04

这是我尝试过的：

我想可能是因为我安装了 anaconda 所以卸载它但没有修复它。然后我在从 .config/code 删除其配置后重新安装了 vs 代码，但这也没有用。还可以从命令面板将 python linting 设置为 true

它没有显示错误曲线：

这是微软的 python 扩展对 linting 的贡献（抱歉可读性差）：

python.linting.pylintEnabled 是：true

python.linting.pylintPath 是：pylint

如何让曲线再次起作用？

【问题讨论】：

你用什么作为你的 linter？安装了吗？ @Boris 我有 Microsoft python 扩展ms-python.python。它说它自己会进行 linting、调试等我不知道，但是如果您在此处发布他们要求的最后两件事的输出，这可能会对其他人有所帮助github.com/microsoft/vscode-python/issues/… 在Output 面板中的Python 的输出和来自的输出Console 在Developer Tools 面板下 @Boris 我已经添加了您要求的内容。但我只在开发者工具的控制台中添加了错误消息。 【参考方案1】：

确保在您的设置中您没有关闭 linting（特别是 Pylint，如果您想使用它）。还要确保您安装了 Pylint 并且 Python 扩展知道它在哪里（通过创建环境并安装到那里或全局安装并设置 "python.linting.pylintPath"）。否则，请检查“输出面板”中“Python”通道的输出，以查看 Pylint 是如何执行的，并确保在您将其复制并粘贴到终端时可以正常工作。

python.linting.pylintPath 设置为 pylint。我试过$ which pylint 它说“找不到pylint”。所以我用sudo apt-get install pylint 安装了它，它安装了pylint，which pylint 返回了路径。但仍然没有显示错误曲线。（我重新加载了几次 vscode）请指定pylint 的绝对路径，而不仅仅是命令名。问题得到解决我已经发布了解决方案。必须在settings.json 文件中添加"python.linting.pylintEnabled":True【参考方案2】：

在您的settings.json 文件中（在命令面板中搜索settings.json），声明以下内容：

"python.linting.pylintEnabled": true, "python.jediEnabled": false

如果您只想在工作区中进行更改，请更改 .vscode 文件夹中的 settings.json 文件

在最新版本的 Visual Studio 代码中，工作区不会从复选框中注册设置，因此您必须在 settings.json 中明确声明要为工作区启用哪些设置。 Flake8 不受此影响。因此，Pylint 和 Microsoft Python 语言服务器似乎无法正常工作。

旁注：从 sys-temd 对 github.com/microsoft/vscode-python/issues 的回复中获得此解决方案

【讨论】：

布尔 JSON 条目需要小写，即"python.linting.pylintEnabled": true【参考方案3】：
