使用conan安装依赖时报错

Question

今天我下载了 Conan、cmake、Visual studio 代码（包括 C++、C++ makefile、Cmake、Cmake 工具和 conan-tools 扩展）。

为了入门，我从 following 教程开始。一切顺利，直到第 5 步，我收到以下错误：

C:\Users\rik>conan profile new default --detect
ERROR: Profile already exists

C:\Users\rik>conan profile update settings.compiler.libcxx=libstdc++11 default

C:\Users\rik>cd build

在命令行输入'conan install ..'后。

几个小时以来我一直在尝试解决这个问题，但不知道如何继续。有人知道我做错了什么吗？

我目前的柯南简介如下：

[settings]
os=Windows
os_build=Windows
arch=x86_64
arch_build=x86_64
compiler=Visual Studio
compiler.version=16
build_type=Release
compiler.libcxx=libstdc++11
[options]
[build_requires]
[env]

Answer 1

步骤 5 的 getting started 部分说：

If you are using GCC compiler >= 5.1, Conan will set the compiler.libcxx to the old ABI for backwards compatibility. You can change this with the following commands:

但是您使用的是Visual Studio，实际情况并非如此，因此您必须跳过该步骤。

由于您的默认配置文件现在包含 libcxx，您应该将其删除：

conan profile remove settings.compiler.libcxx default
