即使在 python 中安装 libarchive 后，libarchive.public 错误

Question

我在尝试执行 import libarchive.public 时遇到错误。以下是日志文本。我已经使用 pip install libarchive 安装了 libarchive。帮助命令显示库中公共模块的存在，但在导入时仍然出错。任何人都可以帮助我解决这个错误是什么。我认为我做的一切都是正确的。

I had to do it on Linux Mint as I could not find a solution for windows. The modified answer is below.

# Install compiler and tools
$ sudo apt-get install build-essential libtool python-dev

# Install cmake
$ sudo apt-get install cmake

$ wget https://github.com/libarchive/libarchive/releases/download/v3.4.1/libarchive-3.4.1.tar.xz
$ tar -xJf libarchive-3.4.1.tar.xz

# Configure using cmake...
$ mkdir build
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/usr/local ../libarchive-3.4.1

# Now compile and install...
$ make
$ sudo make install

$ sudo sh -c 'echo /usr/local/lib > /etc/ld.so.conf.d/libarchive3.conf'
$ sudo ldconfig

$pip install python-libarchive
