openwrt安装shadowsocks的出错情况如下：

Configuring shadowsocks-libev-spec.
//usr/lib/opkg/info/shadowsocks-libev-spec.postinst: line 4: default_postinst: not found
Collected errors:

Configuring shadowsocks-libev-spec.

//usr/lib/opkg/info/shadowsocks-libev-spec.postinst: line 4: default_postinst: not found

Collected errors:

pkg_run_script: package "shadowsocks-libev-spec" postinst script returned status 127.

pkg_run_script: package "shadowsocks-libev-spec" postinst script returned status 127.
opkg_configure: shadowsocks-libev-spec.postinst returned 127.
1
opkg_configure: shadowsocks-libev-spec.postinst returned 127.

出现这种情况的原因是：

目前提供的 ipk 是 15.05 的SDK编译的, 旧版的 base-files 没有相应的函数去执行 postinst-pkg。

可以修改一下 /lib/functions.sh 添加下面的两个函数.

<span class="pl-en">default_postinst</span>() {
    <span class="pl-k">local</span> ret=0
    <span class="pl-k">local</span> root=<span class="pl-s"><span class="pl-pds">"</span><span class="pl-smi">${IPKG_INSTROOT}</span><span class="pl-pds">"</span></span>
    <span class="pl-k">local</span> pkgname=<span class="pl-s"><span class="pl-pds">"</span><span class="pl-pds">$(</span>basename <span class="pl-smi">${1<span class="pl-k">%</span>.<span class="pl-k">*</span>}</span><span class="pl-pds">)</span><span class="pl-pds">"</span></span>
    <span class="pl-k">if</span> [ <span class="pl-k">-f</span> <span class="pl-s"><span class="pl-pds">"</span><span class="pl-smi">$root</span>/usr/lib/opkg/info/<span class="pl-smi">${pkgname}</span>.postinst-pkg<span class="pl-pds">"</span></span> ]<span class="pl-k">;</span> <span class="pl-k">then</span>
        ( <span class="pl-c1">.</span> <span class="pl-s"><span class="pl-pds">"</span><span class="pl-smi">$root</span>/usr/lib/opkg/info/<span class="pl-smi">${pkgname}</span>.postinst-pkg<span class="pl-pds">"</span></span> )
        ret=<span class="pl-smi">$?</span>
    <span class="pl-k">fi</span>
    <span class="pl-k">return</span> <span class="pl-smi">$ret</span>
}

<span class="pl-en">default_prerm</span>() {
    <span class="pl-k">local</span> name=<span class="pl-s"><span class="pl-pds">$(</span>basename <span class="pl-smi">${1<span class="pl-k">%</span>.<span class="pl-k">*</span>}</span><span class="pl-pds">)</span></span>
    [ <span class="pl-k">-f</span> /usr/lib/opkg/info/<span class="pl-smi">${name}</span>.prerm-pkg ] <span class="pl-k">&amp;&amp;</span> <span class="pl-c1">.</span> /usr/lib/opkg/info/<span class="pl-smi">${name}</span>.prerm-pkg
    <span class="pl-k">return</span> 0
}

然后在执行安装shadowsocks的命令就可以成功安装了。
