ycm安装完成但进入vim时报错

[realDuang]

YouCompleteMe unavailable: cannot import name _remove_dead_weakref
功能也没有启用。请问这个_remove_dead_weakref包是必要的么

[jaywcjlove]

# 代码提示插件也需要你运行安装哦，不然没有效果嘞
$ cd ~/.vim/plugged/YouCompleteMe
$ ./install.py
# or 新版脚本过时了，推荐上面脚本
$ ./install.sh 

@kelekexiao123 你是通过这个方法安装的吗？

[realDuang]

是的呢，通过install.py装的

[jokechat]

我也是出现这个问题,还没有尝试出解决方案

[jaywcjlove]

通过下面方式，尝试跟你更新 YCM的依赖？

@jokechat @kelekexiao123

cd ~/.vim/plugged/YouCompleteMe
git submodule update --init --recursive

[jaywcjlove]

Vim 版本，需要 vim@8.0 以上，确认一下？

# 更新版本
brew upgrade macvim

brew install macvim --override-system-vim

还有Python 版本好像是 2.7

python --version
# Python 2.7.10

观看执行过程似乎是ok的,
顺序执行

brew reinstall macvim --with-override-system-vim

# 然后执行
./install.py

问题依旧如此

[jaywcjlove]

brew reinstall macvim --with-override-system-vim

是安装 vim ，你需要查看你 vim 的版本 vim@8.0

如果你安装执行成功，你确认一下代码提示是否成功。

一直正常使用,似乎前段时间操作系统更新了几次出现的这种问题,对python不是很了解,尝试copy python2.7.13 旧版本的_io.so文件,重新 install.py也不能解决

[jaywcjlove]

通过 shell 脚本安装吧，试试这个 @jokechat

./install.sh 

[jokechat]

没有作用,shell脚本依然调用的python [摊手]

多谢了,我继续找找其他途径试试看

[sunowsir]

python3 ./install.py --all --system-libclang
