YouCompleteMe (ycm)，无法构建正则表达式模块

如何解决YouCompleteMe (ycm)，无法构建正则表达式模块

我正在尝试为 vim 安装 ycmd 插件（在运行 git submodule update --init --recursive 之后）并且我遇到了：Failed to build regex module。

在“YouCompleteMe”文件夹中运行 ./install.py 后，以下是导致所述错误的上游行：

似乎 /anaconda3/compiler_compat/ld 可执行文件与 YouCompleteMe/third_party/ycmd/third_party/regex-build/3/temp.linux-x86_64-3.7/regex_3/_regex.o 文件不兼容。>

有人知道发生了什么或我可以尝试什么吗？

解决方法

你可以用coc.nvim做代码补全，效果很好，使用起来也很方便。

几年前我曾多次尝试构建 YCM，但最终我放弃了。

,

我发现问题来自 someone hitting the same kind of issue while trying to compile PyTorch :

“整个问题在于，Anaconda 发行版带有自己的 ld 链接器，该链接器位于 /opt/anaconda/compiler_compat/ 中，它掩盖了驻留在 /usr/bin 中的系统 ld。 为了修复我的错误，我运行了 python setup.py clean 然后我临时将 Anaconda 的 ld 链接器重命名为 ld-old 以使其在 PyTorch 安装过程中不可见。从安装阶段删除 -B 选项也可以修复它。”

因此，为 ycm 编译重命名我的 anaconda ld 链接器解决了我的问题。 （我后来改名了）
