安装numpy时的循环依赖

Question

我正在尝试在我的 virtualenv 中安装 numpy，但我面临如下循环依赖：

(test) [hadoop@ip-192-168-26-8 test]$ python -m pip install numpy
Collecting numpy

ERROR: tensorboard 2.1.0 requires werkzeug>=0.11.15, which is not installed.

然后当我尝试安装 grpcio 时

(test) [hadoop@ip-192-168-26-8 test]$ python -m pip install grpcio

我什至不知道为什么它给了我不正确的提示 Successfully installed grpcio-1.26.0，因为当我使用 list 命令时它们没有被添加到我的 pip 中。

你介意用下面的方法卸载 numpy：

pip uninstall numpy

然后使用 --no-cache-dir 选项再次安装它：

pip install numpy --no-cache-dir

另外，看到 pip 升级了。
