尝试安装python软件包时，Mac终端上的“操作不允许”

Question

我正试图在python上安装一个包含以下代码行的包：

git clone https://github.com/dartoon/decomprofile
cd decomprofile
python setup.py develop

在返回错误消息的最后一步之前，它一直运行良好：

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-53720.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:

  https://setuptools.readthedocs.io/en/latest/easy_install.html

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

我是计算机管理员，所以我不知道为什么我没有更改文件的权限。我已经确保我也有完整的磁盘访问权限。我试过这个命令

sudo easy_install

但这也不起作用。我使用Mac OS Catalina在终端应用程序中工作。我最近更新了anaconda3并使用了python3.8，所以我不确定为什么目录上写着2.7--我可以删除这个目录吗

Answer 1

默认情况下，macOS预装了python2.7。Catalina还预装了python3.7。尝试使用python3命令而不是python

您不能删除Python2.7，因为它是系统依赖项
