在 shell 脚本中调用函数时找不到命令

Question

我有一个 shell 脚本，我用它来安装 caffe 但是当我使用嘘命令，它显示函数调用的命令未找到错误。代码如下。

#!/bin/bash

# This script installs (or at least, attempts to install) Caffe in CPU mode
# with Python bindings without root permission. In doing so, it installs the
# following dependencies:
#
# * protobuf
# * cmake
# * gflags
# * glog
# * opencv
# * hdf5
# * python2
# * pip
# * libpng (recent version required for freetype)
# * automake (recent version required for freetype)
# * freetype (required for scikit-image)
# * various python modules
#     - numpy
#     - scipy
#     - scikit-image
#     - protobuf
#     - yaml
# * boost
# * lmdb
# * libtool
# * snappy
# * leveldb
# * openblas

# be tested before updating and committing.

当我尝试致电时出现以下错误sh install_caffe.sh。

=== Installing Protobufs === install_caffe.sh: line 379: install_protobuf: command not found

我在执行之前执行以下步骤。

1. dos2unix caffe_install.sh
2. chmod +x caffe_install.sh

Answer 1

这是一个bash脚本。它不应该与 一起运行sh。相反，运行它bash，或者使其可执行并直接调用它。

另外，该函数被称为install_protobufs，而不是install_protobuf。
