My employer does not grant me permissions to use Python package managers like pip or conda since the websites that host these data are blocked. In ArcMap 10.x I have been able to install third-party python packages (like simpkml, easygui, pyexiv2,or PIL) by downloading the files, use 7-Zip to crack into the files, and locate the Setup.py file. Once I locate the Setup.py file I can open a command window in that location, tell Windows to use path=%path%;C:\Python\27\ArcGIS10.5 then Python Setup.py install to install the package. Then I am free to write code that imports arcpy as well as other libraries without fuss.

This trick does not work with the ArcGIS Pro version of Python 3 since the Python.exe file and the ArcPy library are stored in a locked directory with read only permissions.

Using this information I have created a second Python environment to install third-party packages but there is no Python.exe file in this newly created environment so again, my trick fails to install.

I understand that I can use the ArcGIS Pro Python Package Manager to install some packages but the ones I want to install on not in ESRI list of packages.

How do I install third-party packages so that I can use them in the same version of Python that stores ArcPy?

  • Is the conda command available from your command line? If I understand the documentation correctly a second conda environment is created in your user directory in which you would have write permissions. You would be able to use conda activate to activate that environment and then perform pip install setup.py to install a package from source. – Kersten May 12 '19 at 8:17
  • @Kersten. I can create a new Python environment in my roaming Citrix profile at C:\Users\geraldg\AppData\Local\ESRI\conda\envs\gPython. Opening a command window in this location and typing conda activate returned 'conda' is not a recognized as an internal or external command operable program or batch file. – GBG May 13 '19 at 15:38
