错误：无法为 iOS 项目安装 CocoaPods 依赖项，这是此模板所必需的

Question

我在尝试为 MacOS 安装 React Native 时遇到了这个问题。

$ npx react-native init myproject

我的 Mac 版本是 Catalina 10.15.7 (19H2)。 XCode 是版本 12。

我尝试了 React-Native: Error: Failed to install CocoaPods dependencies for iOS project, which is required by this template 中的所有内容，但没有任何效果。我也调用了 brew install cocoapods。

任何想法如何解决这个问题？这可能与我在目录结构中（在我运行命令的上方）有一个 node_modules 文件夹的事实有关吗？我不知道这个错误是什么意思。

这里也是 missing 命令的输出：

$ /Users/lancepollard/Library/Caches/CocoaPods/Pods/Release/Flipper-Glog/0.3.6-1dfd6/missing --help
/Users/lancepollard/Library/Caches/CocoaPods/Pods/Release/Flipper-Glog/0.3.6-1dfd6/missing [OPTION]... PROGRAM [ARGUMENT]...

Handle `PROGRAM [ARGUMENT]...' for when PROGRAM is missing, or return an
error status if there is no known handling for PROGRAM.

Options:
  -h, --help      display this help and exit
  -v, --version   output version information and exit
  --run           try to run the given command, and emulate it if it fails

Supported PROGRAM values:
  aclocal      touch file `aclocal.m4'
  autoconf     touch file `configure'
  autoheader   touch file `config.h.in'
  autom4te     touch the output file, or create a stub one
  automake     touch all `Makefile.in' files
  bison        create `y.tab.[ch]', if possible, from existing .[ch]
  flex         create `lex.yy.c', if possible, from existing .c
  help2man     touch the output file
  lex          create `lex.yy.c', if possible, from existing .c
  makeinfo     touch the output file
  tar          try tar, gnutar, gtar, then tar without non-portable flags
  yacc         create `y.tab.[ch]', if possible, from existing .[ch]

Answer 1

Removing LDFLAGS and CPPFLAGS 在我的 bashrc 中为我修复了它！

Answer 2

这个错误也发生在我身上。这是因为旧的 CocoaPods 版本。我使用了 1.8.0 版。升级到1.10.1版本后，错误消失了
