ArcGIS Python工具箱集成第三方模块的解决办法

在ArcGIS中开发Python工具箱时，引入ArcPy开发一些空间处理工具和逻辑是没有问题。但是，在更复杂的场景下，就需要依赖其他的Python模块来实现，例如读写word、查询PostgreSQL数据库等。在Python工具箱的代码里引入其他Python模块时，语法检查中，会报下面的错误，代码如下：

import arcpyimport psycopg2class Toolbox(object):def __init__(self):"""Define the toolbox (the name of the toolbox is the name of the.pyt file)."""self.label = "Toolbox"self.alias = ""# List of tool classes associated with this toolboxself.tools = [Tool]class Tool(object):def __init__(self):"""Define the tool (tool name is the name of the class)."""self.label = "Tool"self.description = ""self.canRunInBackground = Falsedef getParameterInfo(self):"""Define parameter definitions"""params = Nonereturn paramsdef isLicensed(self):"""Set whether tool is licensed to execute."""return Truedef updateParameters(self, parameters):"""Modify the values and properties of parameters before internalvalidation is performed. This method is called whenever a parameterhas been changed."""returndef updateMessages(self, parameters):"""Modify the messages created by internal validation for each toolparameter. This method is called after internal validation."""return@staticmethoddef replace_word(doc, tag, pv):# replace in paragraphfor paragraph in doc.paragraphs:if tag in paragraph.text:for run in paragraph.runs:if tag in run.text:run.text = run.text.replace(tag, pv)# replace in tablefor table in doc.tables:for row in table.rows:for cell in row.cells:for paragraph in cell.paragraphs:for run in paragraph.runs:if tag in run.text:run.text = run.text.replace(tag, pv)def execute(self, parameters, messages):"""The source code of the tool."""return

错误：

Traceback (most recent call last):File "<string>", line 3, in <module>ImportError: No module named psycopg2

解决方法

找到ArcGIS安装后，自带的python2.7环境下的Scripts目录，比如我的是C:\Python27\ArcGIS10.8\Scripts。在文件地址栏中输入cmd，然后按回车。 在弹出的cmd命令窗口中，输入pip.exe install psycopg2。注意是pip.exe，和替换自己的模块名。如果安装速度过慢，可以参考https://hanbo./article/details/106068605，配置国内镜像加速回到ArcGIS中，测试Python工具箱，已经没有错误了。
