安裝setuptools的時(shí)候，不能再注冊表中識別出來python2.7

在網(wǎng)上找了方法，僅作筆記，供下次使用

?

方法：

?

新建一個(gè)register.py 文件，把一下代碼貼進(jìn)去，保存（G盤）

?

# # script to register Python 2.0 or later for use with win32all # and other extensions that require Python registry settings # # written by Joakim Loew for Secret Labs AB / PythonWare # # source: # http://www.pythonware.com/products/works/articles/regpy20.htm # # modified by Valentine Gogichashvili as described in http://www.mail-archive.com/distutils-sig@python.org/msg10512.htmlimport sysfrom _winreg import *# tweak as necessary version = sys.version[:3] installpath = sys.prefixregpath = "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!"returnprint "--- Python", version, "is now registered!"returnif (QueryValue(reg, installkey) == installpath andQueryValue(reg, pythonkey) == pythonpath):CloseKey(reg)print "=== Python", version, "is already registered!"returnCloseKey(reg)print "*** Unable to register!"print "*** You probably have another Python installation!"if __name__ == "__main__":RegisterPy()

?

輸入以下命令（register.py 存放在 G盤底下）

?

顯示“python 2.7 is already registered”

再安裝setuptools的時(shí)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(shí)，如果選擇只為當(dāng)前用戶，以上問題是不會出現(xiàn)的，如果選擇所有用戶，那就用上面的方法解決吧。
