使用pip安装Tensorflow时权限被拒绝

Question

When I try to install Tensorflow with pip install tensorflow , I get this exception:

Traceback (most recent call last):

What does it mean? How can I install the tensorflow package?

When I use: sudo pip install tensorflow I now get this exception:

Instead of saying denied it says Operation not permitted

Answer 1

Looks like your user doesn't have the permission to install packages in your system (for all users). Here's how to fix this problem for Linux, macOS and Windows:

Linux / macOS

From your terminal, you can install the package for your user only , like this:

pip install tensorflow --user

OR

You can use su or sudo from your terminal, to install the package as root :

sudo pip install tensorflow

Windows

From the Command Prompt, you can install the package for your user only , like this:

pip install tensorflow --user

OR

You can install the package as Administrator , by following these steps:

1. Run the Command Prompt as Administrator, using the Run This Program As An Administrator option.
2. Run the command pip install tensorflow

Answer 2

你应该用sudo pip来运行它

Answer 3

It clearly seems to be a problem of permissions.

If you are using Ubuntu or Liux OS, the try using:

sudo pip install tensorflow

If you are using Windows then:

Run the Command prompt as Administrator and the run pip install tensorflow

For better getting rid of such issues in future, Using Anaconda .

Answer 4

You need to install with administrator permissions. This can be done with sudo command.

I would suggest also specifying the Python interpreter as well as using pip , to stop the confusion of where pip should install to. By default there are two versions plus those you may have installed yourself.

To install on 2.7 you could use this:

sudo python -m pip install tensorflow

To install on 3.6 you could use this:

sudo python36 -m pip install tensorflow

For 3.5 you could use this:

sudo python3 -m pip install tensorflow

To tell what the version each Python is you can use which python
