[英]why are pylint's error squiggle lines not showing in python visual studio code?
i'm using vscode for python3 in Ubuntu.我在 Ubuntu 中为 python3 使用 vscode。 Error-squiggle-lines have stopped working for Python(it works for other languages).错误波浪线已停止为 Python 工作(它适用于其他语言)。 And I am using Microsoft's Python extension.我正在使用 Microsoft 的 Python 扩展。
vscode v1.41.1
Ubuntu v18.04
vscode v1.41.1
Ubuntu v18.04
this is what i have tried:这是我尝试过的:
.config/code
but that didn't work either.然后我从.config/code
删除了它的配置后重新安装了 vs .config/code
但这也不起作用。it's not showing error squiggle lines:它没有显示错误波浪线:

how to get the squiggle lines to work again?如何让波浪线再次工作?
In your settings.json
file(search for settings.json
in the command palette), declare the following:在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
if you just want the changes in your workspace then change the settings.json
file in .vscode
folder如果你只是想在你的工作空间的变化,然后改变settings.json
文件.vscode
文件夹
In latest version of visual studio code, workspace is not registering settings from checkboxes so you have to explicitly declare in settings.json what settings you want to enable for your workspace.在最新版本的 Visual Studio 代码中,工作区不会从复选框注册设置,因此您必须在 settings.json 中明确声明要为工作区启用的设置。 Flake8 is not affected by this. Flake8 不受此影响。 Pylint and Microsoft Python Language Server seem to be not working due to this.因此,Pylint 和 Microsoft Python 语言服务器似乎无法正常工作。
side note:got this solution from sys-temd's reply on github.com/microsoft/vscode-python/issues旁注:从 sys-temd 在github.com/microsoft/vscode-python/issues上的回复中得到这个解决方案
pip install -U pylint
"python.linting.pylintEnabled": true, "python.jediEnabled": false
声明"python.linting.pylintEnabled": true, "python.jediEnabled": false
Then I try to recreate a brand-new settings.json, pylint turns out working.然后我尝试重新创建一个全新的 settings.json,结果 pylint 工作正常。
Therefore, I trace which line affects pylint.因此,我会追踪哪条线会影响 pylint。
In my case, it's the line beginning from "python.linting.pylintArgs":
就我而言,它是从"python.linting.pylintArgs":
开始的行"python.linting.pylintArgs":
Removing the line beginning from "python.linting.pylintArgs":
will solve the problem.删除从"python.linting.pylintArgs":
行将解决问题。
Make sure in your settings you didn't turn off linting (and specifically Pylint if that's what you want to use).确保在您的设置中您没有关闭 linting(如果您想使用它,特别是 Pylint)。 Also make sure you have Pylint installed and the Python extension knows where it is (either by creating an environment and installing into there or installing it globally and setting "python.linting.pylintPath"
).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"
)。 Otherwise check the output of the "Python" channel in the Output Panel to see how Pylint is being executed and make sure that works when you copy-and-paste it into a terminal as appropriate.否则,请检查输出面板中“Python”通道的输出,以查看 Pylint 的执行方式,并确保在您将其适当地复制并粘贴到终端中时可以正常工作。
pip install -U pylint
解决了我的问题
If the main problem is those squiggle lines or some minor errors in the workspace then you can download the 'pylance extension' and enable it in settings of 'python language server'.如果主要问题是工作区中的那些波浪线或一些小错误,那么您可以下载“pylance 扩展”并在“python 语言服务器”的设置中启用它。 This language server is even better (i think) because it is lighter than 'jedi' language server and also tells about the unused modules and variables or even the undefined variables as those squiggle lines show.这个语言服务器甚至更好(我认为),因为它比“绝地”语言服务器更轻,并且还告诉了未使用的模块和变量甚至未定义的变量,如那些波浪线所示。
