使用Mason安装pylsp后nvim出现pylsp.plugins.rope_rename缺失错误

通过Mason安装pylsp后，启动Neovim时触发如下错误：

已尝试重新安装pylsp、手动安装rope，问题未解决。

1. 安装pylsp-rope插件到Mason的虚拟环境 #

Mason为每个包创建独立虚拟环境，直接全局安装的依赖无法被pylsp识别，需先激活对应虚拟环境：

source /home/wiskani/.local/share/nvim/mason/packages/python-lsp-server/venv/bin/activate

安装pylsp专属的rope重命名插件：

pip install pylsp-rope

安装完成后退出虚拟环境：

deactivate

2. 禁用rope_rename插件（无需安装依赖） #

如果不需要重命名功能，可在pylsp配置中直接禁用该插件，避免加载失败：

require('lspconfig').pylsp.setup({
  settings = {
    pylsp = {
      plugins = {
        rope_rename = { enabled = false }
      }
    }
  }
})

3. 彻底清理重装pylsp #

若以上方法无效，删除现有安装目录后重新安装：

rm -rf /home/wiskani/.local/share/nvim/mason/packages/python-lsp-server

在Neovim中执行命令重新安装：

:MasonInstall python-lsp-server

安装完成后重复步骤1安装pylsp-rope。
