Anaconda提示加载错误：输入行太长

我在 Windows 7 64 位版本上安装了 Anaconda 64 python 2.7。 安装后，anaconda提示符可以正常启动。但是每当我重新启动/关闭并重新启动笔记本电脑时，anaconda提示符都会显示以下错误消息，并且某些python包在jupyter笔记本中加载时出现问题。

我尝试遵循解决方案here https://stackoverflow.com/questions/682799/what-to-do-with-the-input-line-is-too-long-error-message and here https://stackoverflow.com/questions/12751809/input-line-is-too-long-in-bat-files，但没有成功。

我查看了Anaconda下的Script文件夹，发现错误消息可能来自activate.bat文件。但我不知道下一步该做什么。

任何提示表示赞赏。

我发现，如果您更改对以下 CALL SET 使用单引号：

REM Make sure that root's Scripts dir is on PATH, for sake of keeping activate/deactivate available.
CALL SET "PATH_NO_SCRIPTS=%%PATH:%SCRIPT_PATH%=%%"
IF "%PATH_NO_SCRIPTS%"=="%PATH%" SET "PATH=%PATH%;%SCRIPT_PATH%"

to:

REM Make sure that root's Scripts dir is on PATH, for sake of keeping 
activate/deactivate available.
CALL SET ""PATH_NO_SCRIPTS=%%PATH:%SCRIPT_PATH%=%%""
IF "%PATH_NO_SCRIPTS%"=="%PATH%" SET "PATH=%PATH%;%SCRIPT_PATH%"

为我解决这个问题。这是基于这个answer https://stackoverflow.com/a/3583282/2888347
