repro:\r\n\r\nCreate new bottle application\r\nClick Create when prompted to create a virtual env\r\nMake sure you have app.py open, where there's an `import bottle`\r\nWait for virtual env creation/installation to complete\r\nClick on Manage Packages on the python toolbar, click X to uninstall bottle.\r\n\r\nResult: analyzer process crashes\r\n","author":{"url":"https://github.com/huguesv","@type":"Person","name":"huguesv"},"datePublished":"2019-02-04T03:32:17.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/576/python-language-server/issues/576"}
