為什么pylint 的錯誤波浪線沒有顯示在python Visual Studio 代碼中？

Question

我在 Ubuntu 中為 python3 使用 vscode。 錯誤波浪線已停止為 Python 工作（它適用於其他語言）。 我正在使用 Microsoft 的 Python 擴展。
vscode v1.41.1 Ubuntu v18.04

這是我嘗試過的：

• 我想也許是因為我安裝了 anaconda，所以卸載了它但沒有修復它。
• 然后我從.config/code刪除了它的配置后重新安裝了 vs .config/code但這也不起作用。
• 還從命令面板將 python linting 設置為 true

它沒有顯示錯誤波浪線：

這是 Microsoft 的 python 擴展對 linting 的貢獻（抱歉可讀性差）：

如何讓波浪線再次工作？

Answer 1

在settings.json文件中（在命令面板中搜索settings.json ），聲明以下內容：

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

如果你只是想在你的工作空間的變化，然后改變settings.json文件.vscode文件夾

在最新版本的 Visual Studio 代碼中，工作區不會從復選框注冊設置，因此您必須在 settings.json 中明確聲明要為工作區啟用的設置。 Flake8 不受此影響。 因此，Pylint 和 Microsoft Python 語言服務器似乎無法正常工作。

旁注：從 sys-temd 在github.com/microsoft/vscode-python/issues上的回復中得到這個解決方案

Answer 2

我試過但沒有用

1. pip install -U pylint
2. 聲明"python.linting.pylintEnabled": true, "python.jediEnabled": false

然后我嘗試重新創建一個全新的 settings.json，結果 pylint 工作正常。

因此，我會追蹤哪條線會影響 pylint。

就我而言，它是從"python.linting.pylintArgs":開始的行"python.linting.pylintArgs":

解決方案

刪除從"python.linting.pylintArgs":行將解決問題。

Answer 3

確保在您的設置中您沒有關閉 linting（如果您想使用它，特別是 Pylint）。 還要確保您安裝了 Pylint 並且 Python 擴展知道它在哪里（通過創建環境並安裝到那里或全局安裝並設置"python.linting.pylintPath" ）。 否則，請檢查輸出面板中“Python”通道的輸出，以查看 Pylint 的執行方式，並確保在您將其適當地復制並粘貼到終端中時可以正常工作。

Answer 4

pip install -U pylint

解決了我的問題

Answer 5

如果主要問題是工作區中的那些波浪線或一些小錯誤，那么您可以下載“pylance 擴展”並在“python 語言服務器”的設置中啟用它。 這個語言服務器甚至更好（我認為），因為它比“絕地”語言服務器更輕，並且還告訴了未使用的模塊和變量甚至未定義的變量，如那些波浪線所示。
