libpng15.so.15: cannot open shared object file该怎么解决

这个错误通常是由于系统缺少 libpng 库文件导致的。你可以尝试以下步骤来解决该问题：

1. 安装 libpng 库文件

在终端中运行以下命令来安装 libpng 库文件：

- 对于 Debian/Ubuntu 系统：

sudo apt-get install libpng-dev

- 对于 CentOS/Fedora 系统：

sudo yum install libpng-devel

2. 配置 LD_LIBRARY_PATH 环境变量

如果上述步骤无法解决问题，你可以尝试配置 LD_LIBRARY_PATH 环境变量。在终端中运行以下命令：

export LD_LIBRARY_PATH=/usr/local/lib

或者将其添加到 ~/.bashrc 文件中：

echo "export LD_LIBRARY_PATH=/usr/local/lib" >> ~/.bashrc

然后运行以下命令使其生效：

source ~/.bashrc

以上是两种解决该问题的方法。希望能对你有所帮助。

wkhtmltopdf: error while loading shared libraries: libpng15.so.15: cannot open shared object file: No such file or directory

这个错误是由于缺少libpng15.so.15库文件导致的。你可以通过以下步骤来解决这个问题：

1. 首先，确认你的系统中是否安装了libpng库文件。你可以使用以下命令来检查：

   dpkg -l libpng*

如果libpng库文件没有安装，则需要通过以下命令安装：

   sudo apt-get install libpng-dev

2. 如果libpng库文件已经安装，但是仍然无法找到libpng15.so.15库文件，则可以通过以下命令创建软链接：

   sudo ln -s /usr/lib/x86_64-linux-gnu/libpng16.so.16 /usr/lib/x86_64-linux-gnu/libpng15.so.15

这个命令将会创建一个名为libpng15.so.15的软链接，它指向libpng16.so.16库文件。这个软链接将会解决wkhtmltopdf无法找到libpng15.so.15库文件的问题。

希望这个解决方案能够帮助你解决这个问题。

libpng12.so.0: cannot open shared object file: No such file or directory

This error message usually occurs when the system is unable to find the required shared library file, libpng12.so.0, during runtime. This library is related to the PNG image format.

To resolve this, you can follow these steps:

1. Check if the libpng12 package is installed on your system. You can do this by running the following command:

   dpkg -l | grep libpng12

If the package is not found, you can install it using the package manager specific to your Linux distribution. For example, on Ubuntu, you can run:

   sudo apt-get install libpng12-0

2. If the package is already installed, but the shared library file is still missing, it might be due to a version mismatch. In such cases, you can try creating a symlink to a compatible version of the library. For example, if you have libpng12.so.0.50.0 available, you can create a symlink as follows:

   sudo ln -s /usr/lib/libpng12.so.0.50.0 /usr/lib/libpng12.so.0

3. After performing the above steps, try running your program again. It should be able to find the libpng12.so.0 library and execute without any issues.

Please note that the specific steps may vary depending on your Linux distribution and version.
