尝试在全新安装的 Ubuntu 20.04 上安装 Watchman for React Native。
我正在使用以下步骤（但如果有更好的方法 - 或者如果您可以完全避免使用 Watchman，我会很感兴趣）...
git clone https://github.com/facebook/watchman.git -b v4.9.0 --depth 1
cd watchman/
git checkout
./autogen.sh
./configure --without-python --without-pcre --enable-lenient
make
我在“make”步骤中收到下面显示的错误。
我见过数字 的 问题与建筑守望者有关，但我还没有见过这种情况。

答案1
只需安装相同的 watchman 4.9.0包裹从官方存储库使用以下命令（也许可以咨询官方指南)：
sudo add-apt-repository universe
sudo apt-get update
sudo apt-get install watchman
如果您仍然确定编译 - 安装依赖项，然后使用以下命令编译应用程序：
sudo apt-get install git build-essential libtool libssl-dev pkg-config
cd ~/Downloads
git clone https://github.com/facebook/watchman.git -b v4.9.0 --depth 1
cd watchman
./autogen.sh
./configure --without-python --without-pcre --enable-lenient
make -j$(nproc)
sudo make install
答案2
您可以使用这些命令
sudo apt update
然后运行
sudo apt -y install watchman
