Python version 2.7 required, which was wasn't found in the Regi

When installing the PIL library, you will be prompted directly: Python version 2.7 required, which is not found in the registry.

The main idea is that you can't find the registry and search the solution online.

Create a new register.py file to write code to:

The code is as follows:

Import Sys

From _winreg Import *

# Tweak as necessary
Version = Sys.version[:3]
InstallPath = Sys.prefix

Regpath = "software\\python\\pythoncore\\%s\\"% (version)
Installkey = "InstallPath"
Pythonkey = "PythonPath"
Pythonpath = "%s;%s\\lib\\;%s\\dlls\\"% (
InstallPath, InstallPath, InstallPath
)

Def registerpy ():
Try
reg = Openkey (HKEY_CURRENT_USER, Regpath)
Except EnvironmentError as E:
Try
reg = CreateKey (HKEY_CURRENT_USER, Regpath)
SetValue (Reg, Installkey, REG_SZ, InstallPath)
SetValue (Reg, Pythonkey, REG_SZ, Pythonpath)
Closekey (REG)
Except
Print "* * * Unable to register!"
Return
Print "---Python", version, "is now registered!"
Return
if (QueryValue (Reg, installkey) = = InstallPath and
QueryValue (Reg, pythonkey) = = Pythonpath):
Closekey (REG)
print "= = = Python", version, "is already registered!"
Return
Closekey (REG)
Print "* * * Unable to register!"
Print "* * * you probably has another Python installation!"

Start the command to cut to the register.py file directory to execute:

Reinstall PIL, error resolved, installation succeeded.

If the Win7 64-bit user installs the Python 32-bit program, the above problem does not occur if you select only for the current user. If you select all users, try to resolve them using the methods above.

Tip Other versions of the workaround are similar.
