在Python docker容器中安装watchman错误

Question

如何将watchman安装到我的python docker容器中?我试过按照watchman文档中的描述从源代码安装它，但没有运气。这是我的Dockerfile:

FROM python:3.9
# install watchman
RUN git clone https://github.com/facebook/watchman.git -b v4.9.0 --depth 1 && 
cd watchman && 
./autogen.sh && 
./configure && 
make && 
make install

下面是我尝试构建图像时的错误:

$ docker image build --tag pythonwatchman .
...

#5 143.0   CXX      root/watchman-watchlist.o

#5 146.8 make[1]: Leaving directory '/watchman'
#5 146.8 make: *** [Makefile:1264: all] Error 2

有办法解决这个问题吗?或者是否有更好的方法将watchman安装到这个集装箱中?

或者是否有更好的方法将watchman安装到这个容器中?

是的，你可以直接把它们预编译好的二进制文件安装到容器中，不需要从源代码构建，参见

下一个是完整的解决方案，供参考。

Dockerfile:

FROM python:3.9
ARG WM_VERSION=v2021.03.01.00
# install watchman
RUN wget https://github.com/facebook/watchman/releases/download/$WM_VERSION/watchman-$WM_VERSION-linux.zip && 
unzip watchman-$WM_VERSION-linux.zip && 
cd watchman-$WM_VERSION-linux && 
mkdir -p /usr/local/{bin,lib} /usr/local/var/run/watchman && 
cp bin/* /usr/local/bin && 
cp lib/* /usr/local/lib && 
chmod 755 /usr/local/bin/watchman && 
chmod 2777 /usr/local/var/run/watchman && 
cd .. && 
rm -fr watchman-$WM_VERSION-linux.zip watchman-$WM_VERSION-linux

验证:

$ docker build -t abc:1 .
$ docker run --rm -it abc:1 watchman --version
20210222.215625.0

你可以看到我们现在已经可以运行watchman command了。

BTW，所有预定义的二进制文件都可以在github中找到。
