需要帮助.

推荐答案

此错误(如退出代码:-1073741819")表示wkhtmltopdf进程已被压缩.可能的原因:

This error (like "exit code: -1073741819") means that wkhtmltopdf process was crushed. Possible reasons:

• wkhtmltopdf可执行文件与操作系统不兼容.举例来说，MSVC版本-NReco.PdfGenerator nuget软件包中提供-不支持XP或2003 Server等旧版Windows版本(解决方法是使用MingGW版本).或者，如果Windows可执行文件用于Linux或Mac OS环境(解决方案使用NReco.PdfGenerator.LT nuget +为目标平台部署/安装正确的wkhtmltopdf二进制文件).
• 缺少必需的Universal C运行时库(

• wkhtmltopdf executable is incompatible with the OS. Say, MSVC build - which is shipped in NReco.PdfGenerator nuget package - doesn't support legacy Windows versions like XP or 2003 Server (workaround is using MingGW build). Or if windows executable is used with Linux or Mac OS environment (solution is using NReco.PdfGenerator.LT nuget + deploy/install correct wkhtmltopdf binaries for the target platform).
• missed required Universal C runtime libs ( https://support.microsoft.com/en-us/help/2999226/update-for-universal-c-runtime-in-windows ). This is rare case, as usually these libs are already installed by Windows Update.
• if this error occurs only for concrete HTML this might be a problem with complex HTML layout or heavy JS script. For example, wkhtmltopdf 0.12.4 can crush when ChartsJS library is used by the page (workaround exists).
