Openerp Webkit 报告出现 OsError

Question

我想在我的openerp7上使用webkit报表引擎，我按照这个网站上的教程一步一步操作，链接是 http://castilloinformatica.com/wiki/index.php?title=Webkit_Report_Engine

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

并且把/usr/bin/wkhtmltopdf添加到了设置里。

但是当我尝试打印报价单时，出现了以下错误：

我该如何解决这个错误呢？

Answer 1

尝试在openerp中设置wkhtmltopdf的路径（可以在终端输入“which wkhtmltopdf”来获取这个路径）

在设置->系统参数下进行操作

希望这对你有帮助

Answer 2

这里的问题在于系统参数 webkit_path 的名字有点误导。你可能会想，这个参数应该是 wkhtmltopdf 的路径或目录。

其实，webkit_path 需要包含可执行文件的路径。在 Linux 系统中，这个路径可能是这样的：

/home/my_home_dir/wkhtmltopdf/bin/wkhtmltopdf

在 Windows 系统中，路径可能是：

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

当然，这个路径会根据你安装 wkhtmltox 的位置而有所不同。
