virtualenvwrapper - IOError：[Errno 13]權限被拒絕

Question

我正在嘗試在新的Ubuntu 14.04安裝上安裝virtualenvwrapper 。 我按照這里的步驟將這些行添加到我的.bashrc中：

export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Devel
source /usr/local/bin/virtualenvwrapper.sh

當我嘗試使用source ~/.bashrc時，我收到以下錯誤消息：

virtualenvwrapper.sh: There was a problem running the initialization hooks. 

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenv has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is
set properly.

執行source /usr/local/bin/virtualenvwrapper.sh時會發生這種情況。

有任何想法嗎？ 謝謝。

編輯：雖然我收到此錯誤消息，似乎我的virtualenv有點工作。 我能夠創建新的環境，甚至workon它們。 但是我輸入的每個命令，我都得到了上面的IOError。

固定。 我剛剛卸載了令人討厭的numpy doc包：

sudo pip uninstall numpydoc
