我无法在MacOS Sierra上安装PIP [英] I can't install PIP on MacOS Sierra

问题描述

我已经在Pycharm中运行Python 3一段时间了，我试图安装一个新模块，但安装失败.具体来说，它给了我一个非零退出代码(1)"，并告诉我尝试使用PIP从我的终端安装它.此后，我更新并重新安装了Pycharm，但它仍然不会安装新模块.

I've been running Python 3 in Pycharm for a while now, and I tried to install a new module and it failed to install. Specifically it gave me a "Non-zero exit code (1)" and told me to attempt to install it from my terminal using PIP. I have since updated and reinstalled Pycharm and it still will not install new modules.

在终端机中，我尝试过

pip --version

响应:

-bash: pip: command not found

我查看了如何安装PIP，然后尝试:

I look up how to install PIP, and try:

sudo easy_install pip

它是这样说的:

Searching for pip
Reading https://pypi.python.org/simple/pip/
Download error on https://pypi.python.org/simple/pip/: [SSL:
TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol   version 
(_ssl.c:590) -- Some packages may not be found!
Couldn't find index page for 'pip' (maybe misspelled?)
Scanning index of all packages (this may take a while)
Reading https://pypi.python.org/simple/

-- Some packages may not be found!
No local packages or download links found for pip

Requirement.parse('pip')

因此，我回到Google并进行了更多搜索，发现没有sudo可以尝试使用它，所以

So I go back to google and do a little more searching and find to try it without the sudo, so

easy_install pip

然后它给了我这个

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-2117.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.

，所以我找到了这个较早的问题:为什么Python easy_install在我的Mac上无法使用吗?

so then I find this earlier question: Why is Python easy_install not working on my Mac?

我尝试:

sudo rm -f /usr/bin/easy_install*

它给了我

rm: /usr/bin/easy_install: Operation not permitted
rm: /usr/bin/easy_install-2.6: Operation not permitted
rm: /usr/bin/easy_install-2.7: Operation not permitted

因此，我发现了这个老问题:在macOS上安装pip确实可以(不再)，它有2条回答说只能安装自制软件.所以我尝试:

So then I find this old question: Installing pip on macOS does not work (anymore), which has 2 answers saying to just install homebrew. So I try that:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.comnn
/Homebrew/install/master/install)"

自制软件安装完毕，我想我已经准备好了.

Homebrew installs, and I think I'm ready to go.

pip --version

-bash: pip: command not found

我尝试过

echo $PATH

我忘记了我最初是通过Anaconda使用Python并将其删除的，而这可能正是由此开始的.有什么办法可以解决这个问题?

I had forgotten that I originally used Python through Anaconda and removed it, and that's probably what started this. Is there any way to fix this?

推荐答案

对于Mac OS Sierra，无法通过 easy_install

For Mac OS Sierra, cannot install pip via easy_install

因此，请按如下所示使用curl安装pip，

So install pip using curl as follows,

curl https://bootstrap.pypa.io/get-pip.py | sudo python
