{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Horrible experience with Python Language Server","articleBody":"Hello everyone,\r\n\r\nLately, python language server is **super** laggy  and buggy (+ https://github.com/microsoft/vscode-python/issues/8768)\r\n\r\n1. Often Language Server emits errors like below and my guess it depends on \"weather conditions\" - absolutely unpredictable.\r\n\r\n```\r\nUnable to open 'python.pyi': Unable to read file (Error: File not found (/Users/artemav/Library/Caches/Microsoft/Python Language Server/stubs.v4/fJB3UsE4Gq6YclHi4GoLw6ngBkMtdMTdkOlmPhNG7K8=/python.pyi)).\r\n```\r\n\r\n2. I cannot get any reasonable autocompletion, even for standard python things! Sometimes, I see this error in \"Developer Tools\".\r\n\r\n```\r\nERR No application in the Launch Services database matches the input criteria.: Error: No application in the Launch Services database matches the input criteria.\r\n```\r\n\r\n3. At workspace some folders are indexed and others are not, but have similar code and use same dependencies...\r\n\r\n**PS: I have to switch to Pycharm! I'm ready to help with debugging the issue and I'm sorry not providing MWE how to reproduce it, because all logs are nearly empty:**\r\n\r\n```\r\n[Info  - 9:23:53 PM] Analysis cache path: /Users/artemav/Library/Caches/Microsoft/Python Language Server\r\n[Info  - 9:23:53 PM] Microsoft Python Language Server version 0.4.114.0\r\n[Info  - 9:23:53 PM] Workspace root: /Users/artemav/code/bayesian-optimization\r\n[Info  - 9:23:53 PM] GetCurrentSearchPaths /Users/artemav/anaconda3/envs/tf/bin/python \r\n[Info  - 9:23:53 PM] Interpreter search paths:\r\n[Info  - 9:23:53 PM]     /Users/artemav/anaconda3/envs/tf/lib/python3.7\r\n[Info  - 9:23:53 PM]     /Users/artemav/anaconda3/envs/tf/lib/python3.7/lib-dynload\r\n[Info  - 9:23:53 PM]     /Users/artemav/.local/virtual-site-packages\r\n[Info  - 9:23:53 PM]     /Users/artemav/anaconda3/envs/tf/lib/python3.7/site-packages\r\n[Info  - 9:23:53 PM]     /Users/artemav/code/grand_prix\r\n[Info  - 9:23:53 PM]     /Users/artemav/code/GPflow\r\n[Info  - 9:23:53 PM] User search paths:\r\n[Info  - 9:23:56 PM] Initializing for /Users/artemav/anaconda3/envs/tf/bin/python\r\n[Info  - 9:23:58 PM] Analysis caching mode: None.\r\n```\r\n\r\n**OS: macOS Mojave 10.14.6\r\nVersion: 1.40.1\r\nCommit: 8795a9889db74563ddd43eb0a897a2384129a619\r\nDate: 2019-11-13T16:47:44.719Z\r\nElectron: 6.1.2\r\nChrome: 76.0.3809.146\r\nNode.js: 12.4.0\r\nV8: 7.6.303.31-electron.0\r\nOS: Darwin x64 18.7.0**\r\n","author":{"url":"https://github.com/awav","@type":"Person","name":"awav"},"datePublished":"2019-11-25T11:00:48.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/1813/python-language-server/issues/1813"}
