打开终端柱导出时'；不是有效的标识符'；对于Python源代码激活

我正在运行MacOSXV10.9.2。当我登录到我的终端时，我立即收到以下信息：

Last login: Wed May 14 22:45:00 on ttys007
-bash: export: `/Users/NabilKaz/Library/Enthought/Canopy_64bit/User/bin/activate': not a valid identifier

我使用的是Enthound Canopy，我猜它正在激活一个Python虚拟环境

以下是我的.bash_配置文件的内容：

export PATH="/usr/local/mysql/bin:$PATH"L_ENV_DISABLE_PROMPT=1 source /Users/NabilKaz/Library/Enthought/Canopy_64bit/User/bin/activate


[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

# Added by Canopy installer on 2014-02-19
# VIRTUAL_ENV_DISABLE_PROMPT can be set to '' to make bashprompt show that Canopy is active, otherwise 1
VIRTUAL_ENV_DISABLE_PROMPT=1 source /Users/NabilKaz/Library/Enthought/Canopy_64bit/User/bin/activate

这一行：

export PATH="/usr/local/mysql/bin:$PATH"L_ENV_DISABLE_PROMPT=1 source /Users/NabilKaz/Library/Enthought/Canopy_64bit/User/bin/activate

应该是

export PATH="/usr/local/mysql/bin:$PATH"
L_ENV_DISABLE_PROMPT=1 source /Users/NabilKaz/Library/Enthought/Canopy_64bit/User/bin/activate

---

在导出行中的

L\u ENV\u DISABLE\u PROMPT=1

前面加一个空格。
