我正在尝试在我的Ubuntu 15.10 PC上设置虚拟环境。在我的主目录中，我运行了以下命令：
virtualenv python
source python/bin/activate
pip install ujson
以下是~/.pip/pip.log的内容（下半部分）：

我已尝试安装其他类似的结果包（例如numpy）;编译完成，但在尝试运行install_lib时会爆炸。
答案 0 :(得分：23)
您是否尝试过更新setuptools？
pip install -U setuptools
然后：
pip install ujson
答案 1 :(得分：6)
这可能是“ setuptools”过时的问题。
pip install --upgrade setuptools
应该解决问题。
答案 2 :(得分：-4)
我更新到Ubuntu 16.04，并且在修改了virtualenv并从头开始之后，再没有看到这个问题。
