Question

我正在创建一个虚拟环境并安装包。在shell脚本中，我可以安装所有的包。但在我的python代码中，在安装pytest，pytest-cov等时收到权限被拒绝错误消息

外壳代码

VIRT_DIR=virt_folder
pip install --user virtualenv
virtualenv $VIRT_DIR
. $VIRT_DIR/bin/activate
pip install pylint
pip install coverage
pip install pytest
pip install pytest-cov
pip install virtualenvwrapper

Python代码（版本2.7）

VIRT_DIR = "virt_folder"
subprocess.call("pip install --user virtualenv", shell=True)
subprocess.call("virtualenv " + VIRT_DIR, shell=True)
subprocess.call(". " + VIRT_DIR + "/bin/activate", shell=True)
subprocess.call("pip install pylint", shell=True)
subprocess.call("pip install coverage", shell=True)
subprocess.call("pip install pytest", shell=True)
subprocess.call("pip install pytest-cov", shell=True)

错误讯息：

You are using pip version 9.0.1, however version 9.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

在Linux的虚拟环境中使用python安装软件包（Bash to Python）
