python - Openerp Webkit报告提供OsError

我想将webkit报表引擎与openerp7一起使用，我在此站点http://castilloinformatica.com/wiki/index.php?title=Webkit_Report_Engine上的此站点教程中按照确切的步骤进行操作

我已经安装了这些模块，

sale,
report_webkit,
base_headers_webkit,
report_webkit_chapter_server,
invoice_webkit,
sale_order_webkit

并将/ usr / bin / wkhtmltopdf添加到设置中

当我尝试打印报价单时，出现以下错误：

我如何摆脱这个错误

最佳答案

这里的问题是系统参数webkit_path的名称具有误导性。您会想象这是wkhtmltopdf的路径/目录。

webkit_path必须包含可执行文件的路径。在Linux中，例如

/home/my_home_dir/wkhtmltopdf/bin/wkhtmltopdf

在Windows中可能是

C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe

当然取决于wkhtmltox的安装路径。
