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？或者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，你能告诉我如何安装 google 的 re2 c++ 和 re2以简单的方式？我对他们写的关于如何安装的内容感到困惑。

在尝试了 MattDMo 的解决方案后，我得到了这个：

Answer 1

您需要做的就是克隆 libre2 Github repo along with the pyre2 Github 存储库（因为 pip 可用的 PyPI 版本在代码中有错误），构建并安装 libre2 首先，然后构建并安装 pyre2.

启动您最喜欢的终端应用程序。
在您的 $HOME 中创建 src 目录用于存储源代码：
```
mkdir ~/src
```
输入src目录：
```
cd ~/src
```

克隆存储库（假设您已安装 git）：

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

输入re2目录：
```
cd re2
```
制作：
```
make
```
假设没有错误，make install:
```
sudo make install
```

克隆 pyre2 github repo

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

切换到仓库目录：
```
cd ~/src/pyre2
```
建造：
```
python setup.py build
```
安装：
```
sudo python setup.py install
```

Answer 2

如果您在 ubuntu，在调用

之前需要 sudo apt-get install libre2-dev

pip install re2

Answer 3

我遇到了类似的问题。对我来说，问题是 bash_profile 文件配置不正确。

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)

打开终端并运行源命令以应用更改：

source ~/.bash_profile

安装后 re2 使用 pip

pip install re2

pip install re2 报错

pip install re2 gives an error

c++

python

pip

re2
