Python，PIP，线分析器的失败构建轮

Question

我正在尝试为 ipython 安装线分析器。我正在使用 anaconda 来使用 python。

当前版本的python是：

Python 3.6.2 |Anaconda, Inc.| (default, Sep 19 2017, 08:03:39) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>

当我尝试使用 pip 安装线路分析器时，这是我得到的错误输出。

注意：我正在用 python 运行 anaconda。

Answer 1

您应该通过 Conda 存储库进行安装。

conda install -c anaconda line_profiler 

Answer 2

错误非常明显：

error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

我假设您没有安装 Microsoft Visual C++ 构建工具。
