【围观】麒麟芯片遭打压成绝版，华为亿元投入又砸向了哪里？>>>

1.安装vundle插件；
2.安装vim-go；
3.安装最为头大的YouCompleteMe；
通过git clone 来离线安装YouCompleteMe。步骤如下：
cd ~/.vim/bundle
然后执行 git clone https://gitee.com/Random_Coder/YouCompleteMe.git
把YouCompleteMe目录的所有者改为当前用户(bysu) sudo chown -R bysu:bysu YouCompleteMe
然后执行 git submodule update --init --recursive

报上面的错一般是因为curl的postBuffer的默认值太小和git clone速度太慢，可能被限制了，现在贴出这两方面的解决方案。
postBuffer的默认值太小：
在这里，笔者把postBuffer的值配置成500M，对笔者来说已经够了。可以根据你需要下载的文件大小，将postBuffer值配置成合适的大小。 git config --global http.postBuffer 524288000
这样已经配置好了，如果你不确定，可以根据以下命令查看postBuffer。
git config --list

git clone速度太慢
1、查找域名对应的ip地址，并修改hosts文件
先执行 pacman -Sy dnsutils 安装dnsutils，要不会提示没有nslookup命令。 ifconfig,route在net-tools中，nslookup,dig在dnsutils中，ftp,telnet等在inetutils中,ip命令在iproute2中 ；netcfg
nslookup github.global.ssl.fastly.Net
Server: 127.0.0.53
Address: 127.0.0.53#53
Non-authoritative answer:
Name: github.global.ssl.fastly.Net
Address: 151.101.229.194
nslookup github.com
Server: 127.0.0.53
Address: 127.0.0.53#53
Non-authoritative answer:
Name: github.com
Address: 13.229.188.59
sudo vim /etc/hosts
在文末加上下面两行，下面分别对应上面查出来标了底色部分的内容。然后重启网络服务，archlinux上重启网络服务的命令找到了，但是提示不对，反正我是直接重启了的。

解决掉git clone慢的问题后，可以直接通过git clone把相关文件下到对应的目录 cd /home/bysu/.vim/bundle/YouCompleteMe/third_party git clone https://github.com/Valloric/ycmd
继续执行 git submodule update --init --recursive
不行就多试几次，搞完之后，要安装
编译之前先安装： cmake gcc sudo pacman -Sy cmake gcc
安装完后，开始执行下面进行编译 cd ~/.vim/bundle/YouCompleteMe ./install.py ##########如果需要支持golang######## ./install.py --go-completer ##########如果需要同时支持多种语言如：golang，java，C######## ./install.py --go-completer --java-completer --clangd-completer ##########如果需要插件当前支持的所有语言######## ./install.py --all
开始编译之后，我被卡在了45%那个地方，我以为是树莓派性能太差了的原因，第二天起来还是在45%，打算留个三天三夜，谁知道过一两个小时就报错了。这个时候连报错都觉得是好消息——报错没关系，就怕卡在那里又没错误。 [ 42%] Building CXX object BoostParts/CMakeFiles/BoostParts.dir/libs/regex/src/regex_raw_buffer.cpp.o [ 45%] Building CXX object BoostParts/CMakeFiles/BoostParts.dir/libs/regex/src/regex_traits_defaults.cpp.o c++: fatal error: Killed signal terminated program cc1plus compilation terminated. make[3]: *** [BoostParts/CMakeFiles/BoostParts.dir/build.make:232: BoostParts/CMakeFiles/BoostParts.dir/libs/regex/src/instances.cpp.o] Error 1 make[3]: *** Waiting for unfinished jobs.... make[3]: Leaving directory '/tmp/ycm_build_galdq8zl' make[2]: *** [CMakeFiles/Makefile2:115: BoostParts/CMakeFiles/BoostParts.dir/all] Error 2 make[2]: Leaving directory '/tmp/ycm_build_galdq8zl' make[1]: *** [CMakeFiles/Makefile2:149: ycm/CMakeFiles/ycm_core.dir/rule] Error 2 make[1]: Leaving directory '/tmp/ycm_build_galdq8zl' make: *** [Makefile:131: ycm_core] Error 2 ERROR: the build failed. NOTE: it is *highly* unlikely that this is a bug but rather that this is a problem with the configuration of your system or a missing dependency.

搜索发现是因为树莓派内存不足引起报错。
解决方案： 通过增加swap交换分区来解决 sudo fdisk -l #########上面命令执行后，输出如下################# Disk /dev/mmcblk0: 29.74 GiB, 31914983424 bytes, 62333952 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0xa1b33fd1 Device Boot Start End Sectors Size Id Type /dev/mmcblk0p1 2048 206847 204800 100M c W95 FAT32 (LBA) /dev/mmcblk0p2 206848 62333951 62127104 29.6G 83 Linux ######################### sudo mkdir -p /var/cache/swap/ sudo dd if=/dev/mmcblk0 of=/var/cache/swap/swap0 bs=1M count=512 #/dev/mmcblk0根据上面命令查看 sudo chmod 0600 /var/cache/swap/swap0 sudo mkswap /var/cache/swap/swap0 sudo swapon /var/cache/swap/swap0 但是这样并不能在系统重启的时候自动挂载交换分区, 这样我们就需要修改 fstab. 修改 /etc/fstab 文件, 新增如下内容: /var/cache/swap/swap0 none swap sw 0 0 这样每次重启的时候就会自动挂载swap文件了 ———————————————— 版权声明：本文为CSDN博主「little_stupid_child」的原创文章，遵循 CC 4.0 BY-SA 版权协议，转载请附上原文出处链接及本声明。 原文链接：https://blog.csdn.net/little_stupid_child/article/details/79188015

哈哈哈，功夫不负有心人啊！慢着“ERROR: the build failed.”是什么鬼？竟然构建失败了！！！！
通过搜索
