pip install re2 报错

Question

我正在尝试通过命令pip install re2下载 re2，它给了我这个：

为什么它不起作用？ 还是我应该通过其他方式下载re2？

注意：我发现re2必须已经安装了google的re2 c++，如果是这个问题，你能告诉我如何以简单的方式安装google的re2 c++和re2吗？ 我对他们写的关于如何安装的内容感到困惑。

Answer 1

如果您使用的是 ubuntu，则在调用之前需要sudo apt-get install libre2-dev

pip install re2

Answer 2

您需要做的就是克隆libre2 Github 存储库和pyre2 Github 存储库（因为pip可用的 PyPI 版本在代码中存在错误），首先构建和安装libre2 ，然后构建和安装pyre2 。

1. 启动您最喜欢的终端应用程序。

2. 在$HOME src目录以存储源代码：

    mkdir ~/src

3. 输入src目录：

    cd ~/src

4. 克隆仓库（假设你已经安装了git ）：

    git clone https://github.com/google/re2.git

5. 输入re2目录：

    cd re2

6. 制作：

    make

7. 假设没有错误，进行安装：

    sudo make install

8. 克隆pyre2 github repo

    git clone https://github.com/axiak/pyre2.git ~/src/pyre2

9. 切换到 repo 的目录：

    cd ~/src/pyre2

10. 构建：

     python setup.py build

11. 安装：

     sudo python setup.py install

Answer 3

我遇到了类似的问题。 对我来说，问题是bash_profile文件没有正确配置。

要解决这个问题：

安装jdk

在任何文本编辑器中打开~/.bash_profile或使用vim ~/.bash_profile命令

并添加：

export JAVA_HOME=$(/usr/libexec/java_home)

打开终端并运行 source 命令以应用更改：

source ~/.bash_profile

在此之后使用pip安装re2

pip install re2

Answer 4

您可以使用 package：

pip install pyre2
