在virtualenv中从require.txt安装依赖项时出错

Question

我创建了一个名为bug的virtualenv，并尝试使用-

pip3 install -r requirements.txt

使用上述命令安装模块时，出现以下错误。 我正在使用Python3，并尝试为Coala-quickstart安装依赖项。 以下是终端在尝试从Requirements.txt安装模块时给出的消息。

Answer 1

找不到-lz

您需要安装zlib ：

apt-get install zlib1g

Answer 2

您是否尝试过创建如下所示的virtualenv

Python 3.x

virtualenv --system-site-packages -p python3 venv 

Python 2.7

virtualenv --system-site-packages venv

并且不要忘记通过设置激活您的virtualenv

souce venv/bin/activate

之后，您可以执行

pip3 install -r requirements.txt

Answer 3

这解决了

sudo apt-get install zlib1g-dev

ubuntu倾向于分离开发包，这又使人再次受宠。 因此，安装zlib1g本身不会起作用。 开发包也必须安装。
