安裝 Piggy_NCL 版本畫  shp 出現錯誤
錯誤訊息：
warning:_NclOpenFile: Can not open file <./data/twn_shp/TWN_adm0.shp>; file format not supported or file is corrupted
warning:isfilevar: undefined file returning missing value
fatal:The result of the conditional expression yields a missing value. NCL can not determine branch, see ismissing function

測試：該版本安裝後
僅執行：
  f = addfile( "./data/twn_shp/TWN_adm2.shp" ,"r")
  print(f)

就會有出現上述問題，不知道大家是否有解決方法。

謝謝 lleoiu 建議
找到資料來源：

下載並使用，
執行
$ ncl plot_with_correct_Chinamap.ncl

問題仍存在。

cnmap包需要放在这个目录下$NCARG_ROOT/lib/ncarg/nclscripts/cnmap/

lin54157

謝謝 lleoiu 再次建議

1.複製資料
將資料至於 $NCARG_ROOT/lib/ncarg/nclscripts/cnmap/

確認後如下：
ls $NCARG_ROOT/lib/ncarg/nclscripts/cnmap/*
/home/bean/.Piggy_NCL/lib/ncarg/nclscripts/cnmap/cnhimap.dbf      /home/bean/.Piggy_NCL/lib/ncarg/nclscripts/cnmap/county_2004.prj       /home/bean/.Piggy_NCL/lib/ncarg/nclscripts/cnmap/river.prj

/home/bean/.Piggy_NCL/lib/ncarg/nclscripts/cnmap/cnhimap.shp      /home/bean/.Piggy_NCL/lib/ncarg/nclscripts/cnmap/county_2004.sbx       /home/bean/.Piggy_NCL/lib/ncarg/nclscripts/cnmap/river.shx

/home/bean/.Piggy_NCL/lib/ncarg/nclscripts/cnmap/county_2004.dbf  /home/bean/.Piggy_NCL/lib/ncarg/nclscripts/cnmap/river.dbf

2.再次執行
$ ncl plot_with_correct_Chinamap.ncl

在執行這個區間時

;--- add shp file boundaries ---
;  ShpDir = "./cnmap/" ;"$NCARG_ROOT/lib/ncarg/nclscripts/cnmap/"
  ShpDir = "$NCARG_ROOT/lib/ncarg/nclscripts/cnmap/"
  cnres                       = True
  cnres@gsLineThicknessF      = 2.0
  cnres@gsLineColor           = "red"

  getvalues map4
    "mpMinLatF" : cnres@minlat
    "mpMaxLatF" : cnres@maxlat
    "mpMinLonF" : cnres@minlon
    "mpMaxLonF" : cnres@maxlon
  end getvalues

  plotshp = gsn_add_shapefile_polylines(wks,map4,ShpDir+"cnhimap.shp",cnres)

;---------------------------------------------------------------


仍有

不知道是否大家有這樣的情形

lleoiu

没碰到过。就是你上面这些步骤设置之后，就可以正常出图。
官网下载的NCL 6.4.0 和 6.6.2都可以正常使用。

lin54157

謝謝，不知道是不是我是 win10 +WSL2 環境安裝下才會有問題

lleoiu

应该不会。我在WIN10+WSL下安装的NCL6.6.2，是可以用的。
我是用这个帖子上的方法安装https://bbs.06climate.com/forum. ... B%BC%FC%B0%B2%D7%B0

lin54157

   那我試著，在一次重新安裝看看~~謝謝

lin54157

最後出現了以下訊息
Finished making and Installing <Everything>.
由于GDAL未能成功安装，NCL将无法读取SHP文件。
Piggy_NCL安装完成

~~~ 那應該是我安裝時出現了問題，嘗試解決中
