我想在我的系统上安装eventlet,以便有“Herd”进行软件部署。但是终端显示GCC错误:

为什么找不到Python.h ?

在MacOS上,我在安装fbprophet时遇到了麻烦,它需要pystan,需要gcc来编译。我会始终得到相同的错误:命令'gcc'失败退出状态1

我想我自己解决了这个问题:

我使用brew install gcc来安装最新的版本,最终是gcc-8

然后我确保gcc运行时使用gcc-8。

它可以工作,因为我在我的.zshrc中添加了别名gcc='gcc-8(与.bashrc相同,但用于zsh),或者因为我运行export PATH=/usr/local/bin:$PATH(见评论)

另外:我所有的尝试都是在虚拟环境中,我只成功地在全局安装了fbprophet(用pip),但在venv中仍然没有成功

其他回答

对于openSUSE 42.1 Leap Linux使用此文件

sudo zypper install python3-devel

类似地,我像这样修复了它(注意python34):

sudo yum install python34-devel

如果您正在迁移到更现代的python3版本,例如python3.5到python3.8,如果您已经安装了推荐的库来处理gcc构建python3-dev +其他建议的库,则可能需要检查/升级正在失败的库版本。

这取决于包装。python3的后续版本可能不支持这些包的某些版本。

我使用的是MacOS catalina 10.15.4。上面的解决方案对我来说都没用。对我有用的是:

 >> xcode-select --install
xcode-select: error: command line tools are already installed, use "Software Update" to install updates

>> env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip install psycopg2==2.8.4

对python3使用pip3

这是一篇旧文章,但我只是在AWS EC2安装regex时遇到了同样的问题。这对我来说很有效

sudo yum -y install gcc

和明年

sudo yum -y install gcc-c++
