我正在尝试在我的 Ubuntu 15.10 PC 上设置虚拟环境。从我的主目录中，我运行了以下命令：
virtualenv python
source python/bin/activate
pip install ujson

我尝试安装其他软件包（例如
numpyinstall_lib您尝试过更新安装工具吗？
pip install -U setuptools然后：
pip install ujson这可能是“setuptools”过时的问题。
pip install --升级安装工具
应该可以解决问题。
升级到 Ubuntu 22.04 后，我对其他软件包也遇到了非常类似的问题，它显然来自 setuptools。接下来：pypa/setuptools#3278
我尝试在终端中运行：
export SETUPTOOLS_USE_DISTUTILS=stdlib我的
setuptoolspip install --upgrade --force-reinstall setuptools对于我来说
pip install --升级 pip setuptools 轮
成功了
我更新到 Ubuntu 16.04，在破坏我的 virtualenv 并从头开始之后，没有再看到这个问题。
