我想在我的python virtualenv中使用essentia模块，而python的版本是2.7.6。
我执行后
brew tap MTG/essentia
我无法在我的Pycharm中找到这个模块。
我还尝试使用
安装其他软件包，例如matplotlib
sudo pip install matplotlib
在我的virtualenv路径下。

You are using pip version 7.1.2, however version 8.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
我在Pycharm中检查过，但是在解释器中没有matplotlib模块。
如何在virtualenv中安装软件包？
答案 0 :(得分：1)
您不应该使用brew安装python模块，而应使用pip。在OSX中，以下方法对我有用。
Desktop $ virtualenv myproject # Create the virtual environment
Desktop $ cd myproject # Change into that directory
Desktop $ source bin/activate # Enter the virtual environment
(myproject) $ sudo pip install matplotlib # Install matplotlib
(myproject) $ deactivate # Exit from the virtual environment
请here查看virtualenv的进一步说明。

如果pip包不可用，您可以在本地python目录中找到brew安装。
快速修复：
<input type="text" placeholder="Username" class="label" id="username"><br>
<input type="password" placeholder="Password" class="label" id="password">
$("#username").keypress(function()
{
if($(this).hasClass("label"))
{
$(this).removeClass("label");
$(this).val("");
}
});
$("#password").keypress(function()
{
if($(this).hasClass("label"))
{
$(this).removeClass("label");
$(this).val("");
}
});
长期修复：
