如果不幸删除了lxss或者其他原因 bash 启动失败。可以在CMD里用下面两条命令卸载再重新安装：
echo y|lxrun /uninstall echo y|lxrun /install更新linux子系统，在CMD里运行：
lxrun /update // 更新linux子系统 // - 或者 - lxrun /update /critical // 只更新关键更新，更新完成后会强制关闭linux进程

可用vi编辑：
vi /etc/apt/sources.list
安装 git：
apt-get --assume-yes install git
--assume-yes可选：安装交互全部yes。
删除用remove替换install。
自动移除：
apt-get autoremove
查询7z软件：
apt-cache search 7z

下面是安装swift编译环境的例子（未成功）：
1. 安装 CLang 和 libicu-dev
apt-get install clang libicu-dev
2. 下载swift发行包（到swift.org里找ubuntu14.04平台的版本，目前DEV快照是Swift 3.0预览版本）
curl -O https://swift.org/builds/development/ubuntu1404/swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a/swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04.tar.gz
注：可以先在Windows系统中用下载工具下载好，然后用touch命令在linux文件系统里先创建个同名的文件
root@localhost:~# touch swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04.tar.gz
3. 解压tar.gz包。
tar xzf swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04.tar.gz
如果产生了如下错误：
root@localhost:~# tar zxf swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04.ta r.gz tar: swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04/usr/bin/swift-autolink-extract: Cannot create symlink to ‘swift’: Invalid argument tar: swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04/usr/bin/swiftc: Cannot create symlink to ‘swift’: Invalid argument tar: swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04/usr/bin/lldb-server: Cannot create symlink to ‘lldb-server-3.9.0’: Invalid argument tar: swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04/usr/bin/lldb: Cannot create symlink to ‘lldb-3.9.0’: Invalid argument tar: swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04/usr/bin/lldb-mi: Cannot create symlink to ‘lldb-mi-3.9.0’: Invalid argument tar: swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04/usr/lib/liblldb.so: Cannot create symlink to ‘liblldb.so.3.9.0’: Invalid argument tar: swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04/usr/lib/python2.7/site-packages/lldb/_lldb.so: Cannot create symlink to ‘../../../../lib/liblldb.so’: Invalid argument tar: swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04/usr/lib/python2.7/site-packages/lldb/lldb-argdumper: Cannot create symlink to ‘../../../../bin/lldb-argdumper’: Invalid argument tar: Exiting with failure status due to previous errors
改用7z来解压，设置可执行权限。
rm -rf swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04 apt-get install p7zip-full 7z x swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04.tar.gz 7z x swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04.tar rm swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04.tar chmod +x /root/swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04/usr/bin/*
export PATH=/root/swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04/usr/bin:"${PATH}"
5. 重新载入配置，查看结果：
root@localhost:~# source ~/.bashrc root@localhost:~# swift --version Swift version 3.0-dev (LLVM b010debd0e, Clang 3e4d01d89b, Swift 7182c58cb2) Target: x86_64-unknown-linux-gnu root@localhost:~#
6. 目前仍不能进入REPL环境或者编译swift文件。
编译错误：
<unknown>:0: error: could not load the swift standard library
