Question

我在magento admin中遇到问题：致命错误：Class＆＃39; Mage_Eco_Bank_Helper_Data＆＃39;在第546行的/home/naijaga1/public_html/app/Mage.php中找不到

请通过编写解决方案来帮助我

编辑代码：

---
title: "Waffle"
output:
  pdf_document:
    latex_engine: xelatex
  html_document: default
header-includes:
- \usepackage{fontspec}
- \defaultfontfeatures{Extension = .otf}
- \usepackage{fontawesome}
- \usepackage{tikz}
---

```{r setup, include=FALSE}
library(knitr)
library(tikzDevice)
knitr::opts_chunk$set(warning = FALSE,  error = FALSE, message = FALSE,  results='hide', echo = FALSE, dev = "tikz", external = TRUE)
```

## Waffle Plot

You can also embed plots, for example:  \newline

```{r pressure, echo=FALSE, dev="tikz"}
## ---- waffle_figure ----
loadpackages <- function(package.list = c("ggplot2", "Rcpp")) {
    new.packages <- package.list[!(package.list %in% installed.packages()[,"Package"])]
    if (length(new.packages)){install.packages(new.packages, repos = 'http://cran.us.r-project.org')}
    lapply(eval(package.list), require, character.only = TRUE)}

loadpackages(c("waffle", "extrafont", "grid", "gridExtra", "tikzDevice"))
parts <- c(40, 30, 20, 10)
waffle(parts,
       rows=10,
       use_glyph = "user",
       glyph_size = 5)
```
