适用于Linux的Anaconda 3不能确保吗? [英] Anaconda 3 for Linux Has No ensurepip?

问题描述

这是我的环境:

• CentOS 64位7.2.1511

• CentOS 64-bit 7.2.1511

Anaconda 3 4.1.1 64位(Python 3.5.2)

Anaconda 3 4.1.1 64-bit (Python 3.5.2)

我想通过pyvenv创建venv虚拟环境.不幸的是，我收到此错误消息:

I want to create venv virtual environment by pyvenv. Unfortunately, I got this error message:

$ pyvenv test Error: Command '['/root/test/bin/python', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1

$ pyvenv test Error: Command '['/root/test/bin/python', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1

搜索Internet后，人们说模块ensurepip丢失了.我检查了Anaconda安装路径/opt/anaconda3/lib/python3.5.没有surepip文件夹.

After searching the Internet, people said the module ensurepip is missing. I checked my Anaconda installation path /opt/anaconda3/lib/python3.5. There is no ensurepip folder.

然后，在64位Windows 10上，我检查了Anaconda安装路径D:\win10\Anaconda3\Lib\.有一个surepip文件夹！而且我可以成功运行python -m venv test创建venv.

Then, on my Windows 10 64-bit, I checked my Anaconda installation path D:\win10\Anaconda3\Lib\. There is an ensurepip folder! And I can successfully run python -m venv test to create a venv.

然后，我检查了Anaconda python档案的下载: Windows 10上的D:\win10\Anaconda3\pkgs\python-3.5.2-0.tar.bz2 和 /opt/anaconda3/pkgs/python-3.5.2-0.tar.bz2在CentOS 7上.

Then, I checked the download Anaconda python archives: D:\win10\Anaconda3\pkgs\python-3.5.2-0.tar.bz2 on Windows 10 and /opt/anaconda3/pkgs/python-3.5.2-0.tar.bz2 on CentOS 7.

Windows 10上的一个档案确实有一个surepip子文件夹.但是CentOS 7上的那个却没有！

The one archive on Windows 10 does has a ensurepip subfolder. But the one on CentOS 7 doesn't!

有人知道这种区别吗?这是Anaconda的错误吗?

Does anyone know this difference? Is it a bug of Anaconda?

推荐答案

是的，Linux和Mac OS上的Anaconda3/2没有安装ensurepip.

Yes, Anaconda3/2 for Linux and Mac OS do not have ensurepip installed.

根据此问题记录，这不是错误，这是当Anaconda中的Python在没有--with-ensurepip=install标志的情况下进行编译时，故意 完成了.

According to this issue record, it is NOT a bug, this is done intentionally when the Python in Anaconda being compiled without the --with-ensurepip=install flag.

我认为(Continuum Analytics)的理由是，在Anaconda Distribution 中，conda是负责管理软件包和虚拟环境的老板，并且

I think the rationale (of Continuum Analytics) is that, in Anaconda Distribution, conda is the boss to manage the packages and virtual environments, and

pip(及其setuptools依赖项)独立于Python 作为conda软件包安装.

因此，您可以先运行pyvenv test --without-pip，然后再从

So instead of running pyvenv test, you can first run pyvenv test --without-pip, then download the get-pip.py from pip's homepage, and install the pip in activated test venv.

就像下面这样:

$ #===== First create the venv without pip, and **activate** it.
$ pyvenv test --without-pip
$ cd test/
$ ls bin/
activate       activate.csh   activate.fish  python@        python3@
$ echo $PATH
Whatever/Else:In/Your/System
$ source bin/activate
(test) $ echo $PATH
/Users/YaOzI/test/bin:Whatever/Else:In/Your/System
(test) $
(test) $ #===== Then install the pip independently.
(test) $ python ~/Downloads/get-pip.py
