这段代码中出现了两个问题,一个是缩进问题,一个是字符串连接问题。以下是修改后的代码。
```python
import sys
import arcpy
import string
reload(sys)
sys.setdefaultencoding('utf-8')
try:
workspace = 'C:\\Users\\Administrator\\Desktop\\qwe'
outdb = 'C:\\Users\\Administrator\\Desktop\\lutian.mdb'
arcpy.env.workspace = workspace
files = arcpy.ListFiles('*.*db')
arcpy.env.workspace = outdb
fcs = arcpy.ListFeatureClasses()
fcs = fcs + arcpy.ListTables()
dss = arcpy.ListDatasets()
for File in files:
for fc in fcs:
arcpy.Append_management(workspace + '\\' + File + '\\' + fc, outdb + '\\' + fc)
for ds in dss:
fcs1 = arcpy.ListFeatureClasses(feature_dataset = ds)
for fc1 in fcs1:
arcpy.Append_management(workspace + '\\' + File + '\\' + ds + '\\' + fc1, outdb + '\\' + ds + '\\' + fc1)
except arcpy.ExecuteError:
print(arcpy.GetMessages())
```
修改后的代码中,缩进问题已经被修复,并且修改了字符串连接方式,使用双反斜杠来转义路径中的反斜杠,防止出现字符串连接问题。另外,在except语句中,使用了print函数来输出错误信息。
File ~/anaconda3/envs/songshuhui/lib/python3.8/site-packages/fiona/collection.py:243, in Collection.__init__(self, path, mode, driver, schema, crs, encoding, layer, vsi, archive, enabled_drivers, crs_wkt, ignore_fields, ignore_geometry, include_fields, wkt_version, allow_unsupported_drivers, **kwargs) 241 if self.mode == "r": 242 self.session = Session() --> 243 self.session.start(self, **kwargs) 244 elif self.mode in ("a", "w"): 245 self.session = WritingSession() File fiona/ogrext.pyx:588, in fiona.ogrext.Session.start() File fiona/ogrext.pyx:143, in fiona.ogrext.gdal_open_vector() DriverError: Unable to open A_湖泊.shx or A_湖泊.SHX. Set SHAPE_RESTORE_SHX config option to YES to restore or create it.
这个错误是由于`fiona`库在读取文件时无法打开`.shx`文件或`.SHX`文件导致的。shx`文件是`.shp`文件的索引文件,用于加快对`.shp`文件的访问速度。
解决这个问题的方法是设置`SHAPE_RESTORE_SHX`配置选项为`YES`,以恢复或创建`.shx`文件。可以使用以下命令在Python中设置这个配置选项:
```
import os
os.environ['SHAPE_RESTORE_SHX'] = 'YES'
```
如果这个方法不能解决问题,那么可能是`.shp`文件或`.shx`文件损坏了,需要重新下载或修复这些文件。
