这个错误提示意味着 Python Jedi 服务器在过去的几分钟内崩溃了五次,并且已经无法重新启动。Python Jedi 是一个为 Python 编辑器提供自动补全和代码导航功能的插件。如果它崩溃了,那么你可能会遇到编辑器延迟、崩溃或其他问题。
这种情况下,你可以尝试使用一个不同的自动补全插件,或者尝试重新安装 Python Jedi。如果你使用的是 Visual Studio Code 的话,可以尝试在用户设置中将 "python.jediMemoryLimit" 设置为较大的值,例如 "2048"。这可能会帮助减少 Python Jedi 崩溃的频率。

jedi.vim怎么使用?
要使用jedi-vim插件,需要按照以下步骤进行配置:
1. 安装vim插件管理器vundle。在终端中输入以下命令进行安装:
```shell
git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
```
2. 在vim配置文件~/.vimrc中添加以下内容:
```vim
set nocompatible " be iMproved, required
filetype off " required
" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'
" The following are examples of different formats supported.
" Keep Plugin commands between vundle#begin/end.
" jedi-vim插件
Plugin 'davidhalter/jedi-vim'
call vundle#end() " required
filetype plugin indent on " required
" To ignore plugin indent changes, instead use:
"filetype plugin on
"
" Brief help
" :PluginList - lists configured plugins
" :PluginInstall - installs plugins; append `!` to update or just :PluginUpdate
" :PluginSearch foo - searches for foo; append `!` to refresh local cache
" :PluginClean - confirms removal of unused plugins; append `!` to auto-approve removal
"
" see :h vundle for more details or wiki for FAQ
" Put your non-Plugin stuff after this line
```
3. 保存并退出vim配置文件,然后在vim中输入以下命令安装插件:
```vim
:PluginInstall
```
4. 安装完成后,可以使用jedi-vim插件提供的自动补全功能。在vim中输入以下命令开启自动补全:
```vim
:set omnifunc=jedi#completions
```
然后在编辑Python文件时,输入`.`或者`<C-Space>`即可触发自动补全。
pyqt5 用jedi实现pythonIDE
使用Jedi可以实现Python的智能代码补全、函数跳转、代码重构等功能,结合PyQt5可以实现一个简单的Python IDE。下面是一个简单的示例:
```python
import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QTextEdit
from PyQt5.QtGui import QTextCursor
import jedi
class MainWindow(QMainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.text_edit = QTextEdit(self)
self.text_edit.cursorPositionChanged.connect(self.on_cursor_position_changed)
self.setCentralWidget(self.text_edit)
self.jedi_script = jedi.Script('', 1, 1, '')
def on_cursor_position_changed(self):
cursor = self.text_edit.textCursor()
line_number = cursor.blockNumber() + 1
column_number = cursor.columnNumber()
source_code = self.text_edit.toPlainText()
self.jedi_script = jedi.Script(source_code, line_number, column_number, '')
completions = self.jedi_script.completions()
if completions:
self.show_completions(completions)
else:
self.text_edit.clear()
def show_completions(self, completions):
cursor = self.text_edit.textCursor()
cursor.movePosition(QTextCursor.StartOfWord)
cursor.movePosition(QTextCursor.EndOfWord, QTextCursor.KeepAnchor)
word_under_cursor = cursor.selectedText()
completion_list = [c.name for c in completions if c.name.startswith(word_under_cursor)]
self.text_edit.clear()
self.text_edit.insertPlainText('\n'.join(completion_list))
if __name__ == '__main__':
app = QApplication(sys.argv)
main_window = MainWindow()
main_window.show()
sys.exit(app.exec_())
```
这个例子中,我们使用QTextEdit作为文本编辑器,利用jedi实现了在光标所在位置的代码自动补全功能。当光标位置改变时,我们先利用QTextEdit的textCursor方法获取光标位置,然后获取所在行、列的信息和整个代码,再使用jedi的Script类生成一个脚本对象,最后调用completions方法获取自动补全列表。我们将自动补全列表显示在QTextEdit中,方便用户选择。
