安装 python 模块失败-缺少“limits.h”？

Question

我正在尝试安装一些需要编译的 python 3 模块（例如 regex、cytoolsz、spacy），但它们都失败了，并出现与下面（底部）相同的错误。我尝试使用下面的 grep 检查“limits.h”的存在。我已经重新安装了 gcc、g++ build-essentials、python3-dev 等，但无济于事。

首先要彻底解决您的问题。文件limits.h中的文件/usr/include/linux/由linux-libc-dev包提供。因此，要将头文件放在此位置，您只需通过以下方式安装它：

sudo apt install linux-libc-dev

要提供/usr/include/偶尔使用的头文件，您需要libc6-dev提供它们的包。通过以下方式安装它：

sudo apt install libc6-dev

此外，使用pip3with是不好的做法，sudo因为它倾向于在您的主目录中创建根拥有的文件夹。为了解决这个问题，我假设您已经进行了几次安装，只需收回对以下内容的所有权/home/$USER/.cache/pip：

sudo chown -Rv <your-username>:<your-username> /home/<your-username>/.cache/pip
