在Mac OS X上運行Virtualenv問題

Question

我在Mac OS X 10.6.2（安裝了Xcode）和Python 2.6上使用virtualenv-1.4.5。這是當我嘗試運行virtualenv時得到的...

任何建議爲什麼會引發此錯誤？

Answer 1

還有一個10.6的virtualenv錯誤請參閱the ticket on virtualenv's bitbucket。即使你解決了問題，你仍然會遇到另一個問題（我認爲Python.framework找不到圖像，但我不記得 - 當我碰到這個時，我沒有記下任何註釋）

我做了一些調查，我希望問題的根源可以用Python 2.7來解決 - 當然人們知道它，並且向CPython提交了一個修補程序來修復它。

但是，它看起來好像有人用10.6.2和virtualenv 1.4.5獲得了很好的結果......或者不再使用系統Python（macports，手工構建）。

那麼，錯誤消息包括如下：

你必須有蘋果的開發工具安裝

你？它們位於OSX附帶的單獨XCode磁盤上。

Answer 3

從App Store安裝XCode來解決問題。我有同樣的錯誤，安裝XCode，安裝後運行它，現在virtualenv工作。

Answer 4

有一個使用@ gregglind的virtualenv分支的解決方案。我回答同樣的問題在這裏：mac osx: unable to use virtualenv

git clone https://github.com/gregglind/virtualenv.git 
cd virtualenv 
git checkout feature/install_name_tool 
sudo python setup.py install 

Answer 5

我有同樣的錯誤消息，試圖在上最新最大OSX獅子安裝安裝的XCode運行的virtualenv。

但是：馬克提示on Mar 1 2010：

好代碼說你沒有安裝Xcode的，但你說你有。什麼install_name_tool在命令行說？它應該是install_name_tool - > install_name_tool ==/usr/bin/install_name_tool

我有同樣的問題。我在Lion中安裝了最新的Xcode（10.7.2）。

$ locate install_name_tool 
/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/install_name_tool 
/Developer/usr/bin/install_name_tool 
/Developer/usr/share/man/man1/install_name_tool.1 

我由simlink從/開發人員的/ usr/bin中到/ usr/bin中與

$ sudo ln -s /Developer/usr/bin/install_name_tool /usr/bin/install_name_tool 

進入 '其' 命令產生：

$ which install_name_tool 
/usr/bin/install_name_tool 

之後我做了virtualenv魔術

$ virtualenv -p python2.6 myvirtenv 
Running virtualenv with interpreter /opt/local/bin/python2.6 
New python executable in myvirtenv/bin/python 
Installing setuptools............................done. 
Installing pip...............done. 

Answer 6

install_name_tool到您的路徑

出口PATH = $ PATH：/開發人員在/ usr/bin中

Answer 7

你真正需要做的是安裝Xcode的「命令行工具」，有兩種方法可以做到這一點：

1.-如果您已安裝Xcode，請轉至首選項 - >下載並選擇「命令行工具」。

2.-從「https://developer.apple.com/downloads」下載「用於Xcode的命令行工具」.dmg。

您可以使用App Store安裝Xcode，但默認情況下不包含「命令行工具」。
