在webfaction中安装Python包的问题

Question

我正在尝试使用PIP安装软件包，但它最初对我不起作用，它给出了权限被拒绝的错误，之后当我尝试使用easy_install时，它给了我这个错误： - ＆gt;

在此之后我再次尝试使用pip然后我得到了不同的错误（未被许可拒绝）：

    sys.exit(
  File "/usr/local/lib/python2.4/site-packages/pkg_resources.py", line 357, in load_entry_point

    return ep.load()

                               ^
SyntaxError: invalid syntax

现在我不知道自己做错了什么，有人可以帮助我吗？

编辑： - 由于错误的python版本，syntex errro解决了，我使用的是2.4。

OSError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/site-packages/mezzanine'

$ pip结果

~/bin/pip

Answer 1

只需将--user选项添加到您的pip命令，它将使用您登录的用户权限进行安装：

pip2.7 install mezzanine --user

Answer 2

• 正如Daniel Roseman所说 - 语法错误来自使用Python2.4
• 权限问题是由尝试安装到系统Python引起的，需要sudo或root

可能的解决方案

安装到系统Pyhton（使用sudo）

$ sudo pip install mezzanine

这会破坏系统Python，不太推荐。如果您是例如，那将是可以接受的。在Docker下。

安装到用户个人资料

$ pip install --user mezzanine

它会将软件包安装到用户方案中，不会破坏系统Python。

这是可以接受的，但很快就会变成凌乱的环境来运行代码，因为Python会从系统中导入表单用户方案。

使用virtualenv

假设你安装了virtualenv：

$ cd ~/projects
$ mkdir mezza
$ cd mezza
$ virtualenv venv
$ source venv/bin/activate
(venv)$ pip install mezzanine
$ pip freeze
mezzanine==3.1.8

（冻结会有更多的行）。

这将安装到virtualenv中，它很容易重新创建，破坏，并且不会与其他环境混淆。

使用virtulanevwrapper，您将获得一系列其他工具，这将大大简化您的环境。
