如何将新的默认软件包添加到virtualenv? [英] How to add new default packages to virtualenv?

问题描述

当我创建一个virtualenv时，它会安装setuptools和pip.可以在此列表中添加新软件包吗?

When I create a virtualenv, it installs setuptools and pip. Is it possible to add new packages to this list?

用例示例:

• 按照此解决方案在virtualenv中使用ipython(来自此问题)，需要在每个virtualenv中安装ipython(除非我允许系统-网站软件包).
• 或者，如果我只做Flask/pygame/framework开发，我希望在每个virtualenv中使用它.

• Following this solution to use ipython in virtualenv (from this question) requires installing ipython in every virtualenv (unless I allow system-site-packages).
• Or if I'm doing a only flask/pygame/framework development, I'd want it in every virtualenv.

推荐答案

我采用了与选择正确答案不同的方法.

I took a different approach from what is chosen as the correct answer.

我选择了我的目录，例如~/.virtualenv/deps，并在其中安装了软件包

I chose I directory, like ~/.virtualenv/deps and installed packages in there by doing

pip install -U --target ~/.virtualenv/deps ...

接下来在~/.virtualenv/postmkvirtualenv中，我输入了以下内容:

Next in ~/.virtualenv/postmkvirtualenv I put the following:

# find directory
SITEDIR=$(virtualenvwrapper_get_site_packages_dir)
PYVER=$(virtualenvwrapper_get_python_version)

# create new .pth file with our path depending of python version
if [[ $PYVER == 3* ]];
then
    echo "$HOME/.virtualenvs/deps3/" > "$SITEDIR/extra.pth";
else
    echo "$HOME/.virtualenvs/deps/" > "$SITEDIR/extra.pth";
fi

基本上说出相同意思的帖子.
