到目前为止，我已经尝试了两种方法在this instruction之后的mac上为python2.7安装setuptools 19.2，但我不断收到错误消息：
Downloading https://pypi.python.org/packages/source/s/setuptools/setuptools-19.2.zip

Now working in /tmp/tmpY063sV/setuptools-19.2
Installing Setuptools
running install
Checking .pth file support in /Library/Python/2.7/site-packages/
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-5577.pth'
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:
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.
所以我尝试了另一种方式curl https://bootstrap.pypa.io/ez_setup.py -o - | python，但仍然遇到了同样的错误。所以根据这个回复，这与我放置ez_setup.py的目录有关？或者还有什么东西在这里玩？
更新
使用sudo和sudo !!命令
还尝试sudo chown -R $USER /Library/Python/2.7然后安装它，得到以下消息：

Something went wrong during the installation.
See the error message above.
答案 0 :(得分：1)
您似乎没有Python文件夹的权限
要使用sudo权限运行上一个命令（导致错误），只需运行sudo !!即可运行。
或者，您可以运行sudo chown -R $USER /Library/Python/2.7然后正常安装。
修改：您的新错误消息为：
error: [Errno 2] No such file or directory: '/usr/local/bin/easy_install'
您可以通过以下方式创建该目录：
mkdir /usr/local/bin/easy_install
然后再尝试安装。
