导入pyexcel-xlxs时出错

Question

你好，我正在为我的web应用程序使用pythonanywhere.com，我找到了一种导入pyexcel的方法供我使用，但似乎我做不到，因为这个错误。我是网络应用开发的新手。所以拜托了。我需要你的帮助。

当我通过从github克隆它来安装它时，它做了以下工作：

    $ git clone http://github.com/pyexcel/pyexcel-xlsx.git
    $ cd pyexcel-xlsx
    $ python setup.py install

但我有个错误：

13:56 ~ $ git clone http://github.com/pyexcel/pyexcel-xlsx.git

13:57 ~/pyexcel-xlsx (master)$ python setup.py install
running install
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: '/usr/local/lib/python2.7/dist-packages/test-easy-install-22208.write-test'
The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:
    /usr/local/lib/python2.7/dist-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:
  https://setuptools.readthedocs.io/en/latest/easy_install.html
Please make the appropriate changes for your system and try again.

因为您使用的是PythonAnywhere的标准Python，而不是构建虚拟环境(在您的控制下)，所以setup.py试图安装到系统site-packages目录中，在那里您只有读取权限。如果您想继续不使用虚拟环境，那么在您自己的区域中创建一个目录，并告诉setup.py使用--install-lib dirname选项在那里安装它。

然后，使用PYTHONPATH将export PYTHONPATH=dirname shell环境变量设置为该目录，以便解释器将该目录添加到其模块搜索路径中，您应该可以继续。

@holdenweb的说明很好，但是一个更快的方法就是在bash控制台中运行它：

pip2.7 install --user https://github.com/pyexcel/pyexcel-xlsx/archive/master.zip
