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 ++,如果出现这个问题,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。
在尝试MattDMo的解决方案后,我得到了这个:

您需要做的就是克隆libre2
Github repo以及pyre2
Github repo(由于pip
可用的PyPI版本在代码中有错误),构建和首先安装libre2
,然后构建并安装pyre2
。
在src
中创建$HOME
目录以存储源代码:
mkdir ~/src
输入src
目录:
cd ~/src
克隆回购(假设您已安装git
):
git clone https://github.com/google/re2.git
输入re2
目录:
cd re2
请:
make
假设没有错误,请make install:
sudo make install
克隆pyre2
github repo
git clone https://github.com/axiak/pyre2.git ~/src/pyre2
切换到repo的目录:
cd ~/src/pyre2
构建
python setup.py build
安装:
sudo python setup.py install
答案 1 :(得分:2)
如果您使用的是Ubuntu, 致电
之前需要sudo apt-get install libre2-dev
pip install re2
答案 2 :(得分:0)
我遇到了类似的问题。
对我来说,问题是bash_profile
文件没有正确配置。
要解决此问题:
安装jdk
在任何文本编辑器中打开~/.bash_profile
或使用vim ~/.bash_profile
命令
并添加:
export JAVA_HOME=$(/usr/libexec/java_home)
打开终端并运行source命令以应用更改:
source ~/.bash_profile
此安装后,re2
使用pip
pip install re2
