在Mountain Lion中使用mkvirtualenv時出錯

Question

我有Mountain Lion，我使用這種方法安裝了virtualenv：

sudo easy_install pip
sudo pip install virtualenv virtualenvwrapper
echo "export WORKON_HOME=$HOME/Envs" >> $BASH_CONFIG_FILE
echo "source /usr/local/bin/virtualenvwrapper.sh" >> $BASH_CONFIG_FILE
source ~/.bashrc

當我嘗試使用此命令創建virtualenv時出現問題：

mkvirtualenv test

我收到此錯誤：

New python executable in test/bin/python

你能幫助我嗎？

謝謝！ 標記

Answer 1

您沒有安裝setuptools，

從這里安裝它

如果你從獅子升級到山獅，由於文件系統的一些變化，python安裝會被破壞，理想情況下你應該從xcode安裝命令行工具，然后從python網站安裝python，然后從python網站安裝setuptools，然后通過easy_install安裝pip ，事后一切都會奏效。

Answer 2

問題解決了：

Xcode 4不會自動安裝命令行工具。

基本上，安裝Xcode，進入首選項，然后下載並安裝“命令行工具”。 它現在有效。
