Windows10下Octave便携版安装包报错求助

环境信息 #

• 操作系统：Windows10
• Octave版本：8.4.0便携版（zip压缩包）

核心问题 #

安装本地包、GitHub远程包或使用pkg install -forge命令均失败，报错集中在tar解压环节。

详细报错与排查过程 #

1. 初始本地包安装报错 #

执行pkg install arduino-0.12.1.tar.gz后报错：

>> pkg install arduino-0.12.1.tar.gz
error: unpack: unarchiving program exited with status: 2
tar: /C/PortableApps/PortableApps/octave-8.4.0-w64/arduino-0.12.1.tar.gz: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
error: called from
    unpack at line 287 column 5
    untar at line 48 column 5
    install at line 99 column 9
    pkg at line 619 column 9

2. 调试解压命令 #

在unpack.m中添加调试信息，获取到Octave执行的解压命令：

>> pkg install arduino-0.12.1.tar.gz
Current path: C:\Users\Legion\AppData\Local\Temp\oct-VvVNU6
Command is: tar xf "/C/PortableApps/PortableApps/octave-8.4.0-w64/arduino-0.12.1.tar.gz" 2>&1
error: unpack: unarchiving program exited with status: 2
tar: /C/PortableApps/PortableApps/octave-8.4.0-w64/arduino-0.12.1.tar.gz: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
error: called from
    unpack at line 290 column 5
    untar at line 48 column 5
    install at line 99 column 9
    pkg at line 619 column 9

3. 修改路径格式后的新报错 #

手动将命令中的/C/改为C:/，出现新错误：

>> pkg install arduino-0.12.1.tar.gz
Current path: C:\Users\Legion\AppData\Local\Temp\oct-fCIzKT
Command is: tar xf "C:/PortableApps/PortableApps/octave-8.4.0-w64/arduino-0.12.1.tar.gz" 2>&1
error: unpack: unarchiving program exited with status: 128
tar: Cannot connect to C: resolve failed
error: called from
    unpack at line 290 column 5
    untar at line 48 column 5
    install at line 99 column 9
    pkg at line 619 column 9

注：将该命令复制到cmd中可成功执行，原因是cmd使用系统自带tar，而非Octave内置的Cygwin tar。

4. 修改临时目录无效 #

尝试修改Octave临时目录后，问题未解决：

>> setenv('tmpdir','C:\octave\temp')
>> pkg install arduino-0.12.1.tar.gz
Current path: C:\octave\temp\oct-rF0VdY
Command is: tar xf "/C/PortableApps/PortableApps/octave-8.4.0-w64/arduino-0.12.1.tar.gz" 2>&1
error: unpack: unarchiving program exited with status: 2
tar: /C/PortableApps/PortableApps/octave-8.4.0-w64/arduino-0.12.1.tar.gz: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
error: called from
    unpack at line 290 column 5
    untar at line 48 column 5
    install at line 99 column 9
    pkg at line 619 column 9

5. 远程GitHub包安装同样报错 #

直接从GitHub地址安装，仍出现相同解压错误：

>> setenv('tmpdir','C:\octave\temp')
>> pkg install "https://github.com/gnu-octave/octave-arduino/releases/download/release-0.12.1/arduino-0.12.1.tar.gz"
Current path: C:\octave\temp\oct-OnnVD1
Command is: tar xf "/C/octave/temp/oct-CxgHf3/arduino-0.12.1.tar.gz" 2>&1
error: unpack: unarchiving program exited with status: 2
tar: /C/octave/temp/oct-CxgHf3/arduino-0.12.1.tar.gz: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
error: called from
    unpack at line 290 column 5
    untar at line 48 column 5
    install at line 99 column 9
    pkg at line 619 column 9
