无法在Linux上安装python设置工具

Question

我从我在centos上下载的安装工具中发出以下命令：

python2.7 ez_setup.py install

我收到以下错误：

Downloading https://pypi.python.org/packages/source/s/setuptools/setuptools-6.0.2.zip
Extracting in /tmp/tmp8x3qjd
Now working in /tmp/tmp8x3qjd/setuptools-6.0.2
Installing Setuptools
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/site-packages/test-easy-install-23056.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /usr/local/lib/python2.7/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:

  https://pythonhosted.org/setuptools/easy_install.html

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

Something went wrong during the installation.
See the error message above.

如果像这样使用sudo：

python2.7 ez_setup.py install

它说找不到python2.7命令。

我究竟做错了什么？

Answer 1

最好的选择是做sudo $(which python2.7) ez_setup.py install 。 which会在当前用户的定位程序${PATH}变量。

了解为什么python2.7不在root的路径中也是要研究的东西。

Answer 2

这是一个简单的问题（可能是！）。 这可能会有所帮助！ 以超级用户身份输入：

wget https://bootstrap.pypa.io/ez_setup.py -O - | python - --user

这将下载并安装setuptools 6.0.2：Python软件包索引
