使用Mac OSX管理員賬戶安裝Beautifulsoup

Question

需要幫助.... 我試了很多次，使用管理員帳戶來安裝beautifulsoup4-4.0.0b3，但有很多失敗。我用的MacPro OS X Lion中10.7.2

在下面的終端發生了什麼事：

當我TEPYED：easy_install beautifulsoup4

迴應：

error: can't create or remove files in install directory 
The following error occurred while trying to add or remove files in 
the installation directory: 
[Errno 13] Permission denied: '/Library/Python/2.7/site-packages/ 
test-easy-install-411.write-test' 
The installation directory you specified (via --install-dir, --prefix, 
or the distutils default setting) was: 
    /Library/Python/2.7/site-packages/ 
Perhaps your account does not have write access to this directory? If 
the installation directory is a system-owned directory, you may need to 
sign in as the administrator or "root" account. If you do not have 
administrative access to this machine, you may wish to choose a different 
installation directory, preferably one that is listed in your PYTHONPATH 
environment variable. 
For information on other options, you may wish to consult the 
documentation at:

Please make the appropriate changes for your system and try again. 

，以及自動重複此對話AGIAN：

$ easy_install cd beautifulsoup4-4.0.0b3

它幾乎讓我發瘋。感謝任何人幫我弄清楚 問題是什麼......

Answer 1

錯誤permission denied表明你有寫權限，所以你需要在你的命令前面使用sudo。

使用sudo easy_install beautifulsoup4或更好的是，pip install beautifulsoup4與virtualenv而不必使用sudo。

Answer 2

簡單：嘗試sudo easy_install beautifulsoup4，然後輸入您的管理員密碼。

更難：我會建議設立一個virtualenv。一旦你設置好了，你可以安裝沒有管理員密碼的東西。這也是有利的，因爲如果你搞砸了Python安裝，你可以刪除virtualenv並重新開始。 （你需要安裝XCode來設置一個虛擬環境，所以它可能會有點無用）
