在Python 3.5中安装Pyproj时出错

Question

从前两天开始，我尝试使用pip安装python的pyproj包。但我得到了下面引用的错误。我已经尝试了所有可用的相关解决方案，但无法安装。 提前谢谢

Answer 1

试试这个

easy_install pyproj

或者

sudo easy_install pyproj

或者从pyproj下载tar文件并尝试运行

pip install [path to downloaded tar file]

Answer 2

你需要Python3.5的开发工具

sudo apt-get update
sudo apt-get install python3.5-dev -y 
pip install pyproj

如果使用Python3.6需要更新第二行。

Answer 3

Pyproj需要一个编译器（vcvarsall.bat提示Windows中的Visual C），而您似乎还没有安装这个编译器。我建议下载pre-compiled wheel和install the package from that，而不是从源代码安装。
