即使在python中安装libarchive之后也会出现libarchive.public错误

Question

当我试图执行导入libarchive.public时，我收到了一个错误。下面是日志文本。我已经安装了libarchive使用pip安装libarchive。help命令显示库中存在公共模块，但导入时仍会出现错误。有人能帮我解决这个错误吗？我想我做的一切都是正确的。

Answer 1

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
