即使我输入了确切的路径，Unix 安装程序也找不到文件路径 [英] Unix Installer can't find path to file even though I'm entering the exact path

问题描述

我正在尝试修改更新 Flash 的现有脚本，但安装程序不起作用.

I'm trying to modify an existing script that updates Flash but the installer will not work.

我不断收到以下错误.

安装程序:错误指定的包路径无效:'/Volumes/Flash Player/Install Adob​​e Flash Player.app/Contents/MacOS/Adobe Flash Player Install Manager'.

installer: Error the package path specified was invalid: '/Volumes/Flash Player/Install Adobe Flash Player.app/Contents/MacOS/Adobe Flash Player Install Manager'.

如果我修改它在文件路径末尾说 include.pkg 也不起作用.

It also does not work if I modify it to say include.pkg at the end of the filepath.

这是脚本的其余部分:

#!/bin/sh
# Script to download and install Flash Player.
# Only works on Intel systems.
#

dmgfile="flash.dmg"
volname="Flash"
logfile="FlashUpdateScript.log"
echo "Updating Flash player…"
# Are we running on Intel?
if [ '`/usr/bin/uname -p`'="i386" -o '`/usr/bin/uname -p`'="x86_64" ]; then
    # Get the latest version of Flash Player available from Adobe's About Flash page.
    latestver=`/usr/bin/curl -s http://www.adobe.com/software/flash/about/ | sed -n '/Safari/,/</tr/s/[^>]*>([0-9].*)<.*/1/p'`
    # Get the version number of the currently-installed Flash Player, if any.
    if [ -e "/Library/Internet Plug-Ins/Flash Player.plugin" ]; then
    currentinstalledver=`/usr/bin/defaults read /Library/Internet Plug-Ins/Flash Player.plugin/Contents/version CFBundleShortVersionString`
    else
    currentinstalledver="none"
    fi
    echo "Installed version:                 $currentinstalledver"
    echo "Currently last version to install: $latestver"
# Compare the two versions, if they are different of Flash is not present then download and install the new version.
if [ "${currentinstalledver}" != "${latestver}" ]; then
    echo "UPDATING…"

            /bin/echo "`date`: SUCCESS: Flash has been updated to version ${newlyinstalledver}" >> ${logfile}
            echo "SUCCESS: Flash has been updated to version ${newlyinstalledver}"
        else
            /bin/echo "`date`: ERROR: Flash update unsuccessful, version remains at ${currentinstalledver}." >> ${logfile}
            /bin/echo "--" >> ${logfile}
            echo "ERROR: Flash update unsuccessful, version remains at ${currentinstalledver}."
        fi
    # If Flash is up to date already, just log it and exit.       
    else
        /bin/echo "`date`: Flash is already up to date, running ${currentinstalledver}." >> ${logfile}
        /bin/echo "--" >> ${logfile}

echo "ERROR: This script is for Intel Macs only."
fi

推荐答案

您需要确认路径的每个段都具有允许您写入该目录及其下的任何内容的权限.将以下脚本保存到 PATH 中的目录中(/usr/local/bin 是合适的)或将其保存到 /tmp 目录中并与完整路径一起使用.

You need to confirm that each segment of the path has permissions that would allow you to write to that directory and any below it. Save the following script into a directory in your PATH (/usr/local/bin would be appropriate) OR save it into the /tmp dir and use it with a full path.

cat pathChecker.sh    
#!/bin/bash

path2chk="${@?usage:${0##*/} /path/to/check}"
if ! [[ -d "${path2chk}" ]] ; then
   echo "no directory access to ${path2chk}"
   echo "checking all elements anyway"
fi

echo "${path2chk}"
| sed 's///
/g' 
| while read pathElem ; do
    testPath="${testPath+${testPath}/}${pathElem}"
    #dbg echo "ls -ld "$testPath""
    ls -ld "$testPath"
done


chmod +x pathChecker.sh
pathChecker.sh '/Volumes/Flash Player/Install Adobe Flash Player.app/Contents/MacOS/Adobe Flash Player Install Manager'

应该显示类似的列表

drwxr-x-r-x ..... /Volumes
drwxr------ ..... /Volumes/Flash Player   # bzt!
. . . .
