Question

我尝试创建Python3 virtualenv并测试其中的一些Python代码：

python3 -m venv tbzuploader-py3env
cd tbzuploader-py3env
. ./bin/activate
pip install -e git+https://github.com/guettli/tbzuploader.git#egg=tbzuploader

以下是我得到的输出：

You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

我使用Ubuntu 16.04中的Python：

===> python --version
Python 3.5.2

我做错了什么？

Answer 1

默认venv已安装pip版本8.您应该更新它：pip install --upgrade pip

Answer 2

您需要通过以下命令更新pip版本。

pip install --upgrade pip

安装python3时，会安装pip3。如果您没有其他python安装（如python2.7），则会创建一个指向pip3的链接。 pip一般指向第一次安装。

Python3：在virtualenv中安装失败
