如何将 Python 添加到 Windows 注册表

How to add Python to Windows registry

提问by user2621120

I've downloaded Enthought Canopy EPD Free (now Canopy Express) from https://www.enthought.com/products/epd/free/and want to install SciKit Learn (http://sourceforge.net/projects/scikit-learn/files/) which is not part of the basic EPD Free install.

我已经从https://www.enthought.com/products/epd/free/下载了 Enthought Canopy EPD Free（现在是 Canopy Express）并想安装 SciKit Learn ( http://sourceforge.net/projects/scikit-learn /files/) 这不是基本 EPD 免费安装的一部分。

When trying to install it does not find Python in the Windows registry. How do I adjust the registry so that it recognizes the Enthought version of Python?

尝试安装时，它在 Windows 注册表中找不到 Python。如何调整注册表以使其识别 Python 的 Enthought 版本？

You can find the Python executable with this command:

您可以使用以下命令找到 Python 可执行文件：

C:\> where python.exe

It should return something like:

它应该返回如下内容：

C:\Users\<user>\AppData\Local\enthought\Canopy32\User\python.exe

Open regedit, navigate to HKEY_CURRENT_USER\SOFTWARE\Python\PythonCore\<version>\PythonPathand add or edit the default key with this the value found in the first command. Logout, login and python should be found. SciKit can now be installed.

打开 regedit，HKEY_CURRENT_USER\SOFTWARE\Python\PythonCore\<version>\PythonPath使用在第一个命令中找到的值导航到并添加或编辑默认键。应该可以找到注销、登录和python。现在可以安装 SciKit。

See Additional “application paths” in https://docs.python.org/2/using/windows.html#finding-modulesfor more details.

I faced to the same problem. I solved it by

我面临同样的问题。我解决了

1. navigate to HKEY_CURRENT_USER\Software\Python\PythonCore\3.4\InstallPathand edit the default key with the output of C:\> where python.execommand.
2. navigate to HKEY_CURRENT_USER\Software\Python\PythonCore\3.4\InstallPath\InstallGroupand edit the default key with Python 3.4

1. HKEY_CURRENT_USER\Software\Python\PythonCore\3.4\InstallPath使用C:\> where python.exe命令的输出导航到并编辑默认键 。
2. 导航到HKEY_CURRENT_USER\Software\Python\PythonCore\3.4\InstallPath\InstallGroup并编辑默认键Python 3.4

Note: My python version is 3.4 and you need to replace 3.4 with your python version.

注意：我的python版本是3.4，你需要用你的python版本替换3.4。

Normally you can find Registry entries for Python in HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\<version>. You just need to copy those entries to HKEY_CURRENT_USER\Software\Python\PythonCore\<version>

通常，您可以在HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\<version>. 您只需要将这些条目复制到HKEY_CURRENT_USER\Software\Python\PythonCore\<version>

When installing Python 3.4 the "Add python.exe to Path" came up unselected. Re-installed with this selected and problem resolved.

安装 Python 3.4 时，“将 python.exe 添加到路径”未选中。选择此选项重新安装并解决了问题。

I installed ArcGIS Pro 1.4 and it didn't register the Python 3.5.2 it installed which prevented me from installing any add-ons. I resolved this by using the "reg" command in an Administrator PowerShell session to manually create and populate the necessary registry keys/values (where Python is installed in C:\Python35):

我安装了 ArcGIS Pro 1.4，但它没有注册它安装的 Python 3.5.2，这使我无法安装任何附加组件。我通过在管理员 PowerShell 会话中使用“reg”命令手动创建和填充必要的注册表项/值（其中 Python 安装在 C:\Python35 中）解决了这个问题：

reg add "HKLM\Software\Python\PythonCore.5\Help\Main Python Documentation" /reg:64 /ve /t REG_SZ /d "C:\Python35\Doc\Python352.chm"
reg add "HKLM\Software\Python\PythonCore.5\InstallPath" /reg:64 /ve /t REG_SZ /d "C:\Python35\"
reg add "HKLM\Software\Python\PythonCore.5\InstallPath\InstallGroup" /reg:64 /ve /t REG_SZ /d "Python 3.5"
reg add "HKLM\Software\Python\PythonCore.5\PythonPath" /reg:64 /ve /t REG_SZ /d "C:\Python35\Lib;C:\Python35\DLLs;C:\Python35\Lib\lib-tk"

I find this easier than using Registry Editor but that's solely a personal preference.

我发现这比使用注册表编辑器更容易，但这完全是个人喜好。

The same commands can be executed in CMD.EXE session if you prefer; just make sure you run it as Administrator.

如果您愿意，可以在 CMD.EXE 会话中执行相同的命令；只要确保您以管理员身份运行它。

I had the same issue while trying to install bots on a Windows Server. Took me a while to find a solution, but this is what worked for me:

我在尝试在 Windows Server 上安装机器人时遇到了同样的问题。我花了一段时间才找到解决方案，但这对我有用：

1. Open Command Prompt as Administrator
2. Copy this: reg add HKLM\SOFTWARE\Python\PythonCore\2.7\InstallPath /ve /t REG_SZ /d "C:\Python27" /fand tailor for your specifications.
3. Right click and paste the tailored version into Command Prompt and hit Enter!

1. 以管理员身份打开命令提示符
2. 复制此内容：reg add HKLM\SOFTWARE\Python\PythonCore\2.7\InstallPath /ve /t REG_SZ /d "C:\Python27" /f并根据您的规格进行定制。
3. 右键单击并将定制版本粘贴到命令提示符中，然后按 Enter！

Anyway, I hope that this can help someone in the future.

无论如何，我希望这可以帮助将来的某个人。
