bash: buildtool: command not found

"bash: buildtool: command not found" 是一个常见的错误提示，它表示在你的bash终端中找不到名为"buildtool"的命令。这通常是因为你尝试运行一个不存在的命令或者没有正确安装的命令。

要解决这个问题，你可以采取以下几个步骤：
1. 确认命令是否正确：检查你输入的命令是否正确拼写，并确保你使用的是正确的命令名称2. 检查命令是否存在：使用`which`命令来检查该命令是否存在于系统的可执行路径中。例如，可以运行`which buildtool来检查是否能找到该命令。
3. 确认命令是否已安装：如果命令不存在，可能是因为你没有安装它。你可以通过包管理器来安装该命令，具体方法取决于你使用的操作系统和包管理器。例如，在Ubuntu上，可以使用`apt-get`命令来安装软件包。
4. 检查环境变量：如果命令已正确安装但仍无法找到，可能是因为它的路径没有添加到系统的环境变量中。你可以编辑`.bashrc`或`.bash_profile`文件，并将命令所在的路径添加到`PATH`环境变量中。

希望以上解答对你有帮助！如果你还有其他问题，请随时提问。

npm ERR! gyp verb `which` failed python2 Error: not found: python2

This error occurs when the system cannot find Python2, which is required by Node.js to build native modules using the node-gyp tool.

To resolve this issue, you need to install Python2 on your system and make sure it is accessible via the PATH environment variable.

Here are the steps you can follow to install Python2:

1. Check if Python2 is already installed on your system by running the following command in your terminal:

   python2 --version

If Python2 is already installed, you should see the version number. If not, you will need to install it.

2. Install Python2 using your system's package manager. For example, on Ubuntu, you can run the following command:

   sudo apt-get install python2

On macOS, you can install Python2 using Homebrew:

   brew install python@2

3. Once Python2 is installed, you need to add it to the PATH environment variable. You can do this by adding the following line to your ~/.bashrc or ~/.bash_profile file:

   export PATH="/path/to/python2/bin:$PATH"

Replace /path/to/python2 with the actual path to the directory where Python2 is installed.

4. Save the file and reload your terminal or run the following command to apply the changes:

   source ~/.bashrc

or

   source ~/.bash_profile

Now try running your original command again and it should work without errors.

Failed to execute goal org.bytedeco:javacpp:1.5.9:build (javacpp-cppbuild-compile) on project libnd4j: Failed to execute JavaCPP Builder: Cannot run program "sh" (in directory "D:\IDEA2018\deeplearning4j-master\libnd4j"): CreateProcess error=2, 系统找不到指定的文件。

It seems like you are facing an error while executing the JavaCPP Builder in your Maven project. The error message states that the program "sh" cannot be found in the specified directory, which is causing the build process to fail.

This error is usually caused by a missing or misconfigured shell environment on your system. The "sh" program is a Unix shell that is commonly used on Linux and Mac systems, but it may not be available on Windows systems.

To resolve this issue, you can try one of the following solutions:

1. If you are using a Windows system, you can try installing a Unix-like shell such as Git Bash or Cygwin, which should provide the "sh" program and other Unix utilities that are needed for the build process.

2. If you already have a Unix-like shell installed, you can check your system PATH environment variable to make sure that the directory containing the "sh" program is included. You can do this by running the following command in a terminal:

echo $PATH

This should display a list of directories separated by colons. Make sure that the directory containing the "sh" program is included in this list.

3. If you are still encountering issues, you can try updating your Maven configuration to use a different build tool or version of the JavaCPP library. You can also try reaching out to the JavaCPP community or the developers of the project you are working on for further assistance.
