uname/ps/readlink/dirname - 安装时在react-native中找不到命令问题

Question

我在安装我的react-native项目时遇到此错误-

/Users/username/.rvm/scripts/rvm: line 12: uname: command not found
/Users/username/.rvm/scripts/rvm: line 29: ps: command not found
/Users/username/Desktop/Applications/SegmentTestApp/ios/Pods/../../node_modules/react-native/React/FBReactNativeSpec/../../scripts/generate-specs.sh:
line 27: readlink: command not found
/Users/username/Desktop/Applications/SegmentTestApp/ios/Pods/../../node_modules/react-native/React/FBReactNativeSpec/../../scripts/generate-specs.sh:
line 27: dirname: command not found
/Users/username/Desktop/Applications/SegmentTestApp/ios/Pods/../../node_modules/react-native/React/FBReactNativeSpec/../../scripts/generate-specs.sh:
line 27: cd: : No such file or directory Command PhaseScriptExecution
failed with a nonzero exit code

这是我的 ~/.zshrc 文件 -

export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools
export PATH="/usr/local/opt/coreutils/libexec/gnubin:$PATH"

环境-

❯ echo $PATH
/Users/<username>/.rvm/gems/ruby-3.0.0/bin:/Users/<username>/.rvm/gems/ruby-3.0.0@global/bin:/Users/<username>/.rvm/rubies/ruby3.0.0/bin:/usr/local/opt/coreutils/libexec/gnubin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin:/Applications/Wireshark.app/Contents/MacOS:/Applications/Postgres.app/Contents/Versions/latest/bin:/Users/<username>/Library/Android/sdk/emulator:/Users/<username>/Library/Android/sdk/tools:/Users/<username>/Library/Android/sdk/platform-tools:/Users/<username>/.rvm/bin

解决方案＃1

日志中的以下错误消息表明命令行工具无法理解 RVM 脚本中的 uname 或 ps 引用。

/Users/username/.rvm/scripts/rvm: line 12: uname: command not found

我很好奇uname的下落，所以我这么做了 -

> which uname
/usr/local/opt/coreutils/libexec/gnubin/uname

此路径已添加到我的 .zshrc 文件中，如上面所示，但仍然没有解决问题。

打开RVM脚本后，我发现它没有使用zsh shell，而是使用bash shell，所以我在最后的.bash_profile文件中添加了这个uname路径 -

export PATH=/usr/local/opt/coreutils/libexec/gnubin:$PATH

它开始工作了。

解决方案＃2

其他替代解决方案可以是将 rvm 脚本的 shell 从 zsh 更改为 bash。只需更改脚本的第一行

#!/usr/bin/<<shell name - bash/zsh>>

Answer 2

npm start>react-native start

node_modules/.bin/react-native：第 2 行：sed：找不到命令 node_modules/.bin/react-native：第 2 行：dirname：找不到命令 node_modules/.bin/react-native：第 4 行：uname：找不到命令

解决方案 => 使用“git bash”而不是“powershell”。

它对我有用
