python2.7無法在登錄檔中被識別：python version 2.7 required,which was no
安裝MySQL-python-1.2.4b4.win32-py2.7的時候，不能再登錄檔中識別出來python2.7
方法：新建一個register.py 檔案，把一下程式碼貼進去，儲存
!E:\python2.7
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 “*
print “* You probably have another Python installation!”
if name == “main“:
RegisterPy()
按F5執行，顯示“python 2.7 is already registered”
再安裝setuptools的時候，就能自動識別出來python2.7了。
win7是 64的原因，在安裝python（32位）時，如果選擇只為當前使用者，以上問題是不會出現的，如果選擇所有使用者，那就用上面的方法解決吧。
